History of Mobile Platforms

Introduction

The cost of mobile phones was high in the initial stages. The mobile owners had to pay the bill for outgoing calls and incoming calls. People considered mobile phones as a luxury.

The cell phone rates declined from the year 2000, and the users only had to pay the bills for outgoing calls and send SMS to others.

Mobile usage restricted users from calling and sending text messages. Even the games on the mobile platform were limited.

There was no scope for downloading the apps or music to your phones.

Even the mobile screens had a monochromic appearance. However, after 2005, the color mobile came up with color screens with a camera.

In 2008, smartphones had replaced mobile phones with larger screens, virtual keyboards, downloadable apps, and others.

Mobile platforms - History

a. Psion EPOC 

 It is the first recognizable mobile platform that started with handheld computers or palmtops. EPOC was the first mobile platform released in the early 1990s. The developers used Open Programming Language (OPL) to create EPOC with 16-bit machines that enabled the users to operate Word processors, databases, spreadsheets, and others. It had inspired the developers to come with the later models in EPOC operating systems. The developers successfully came up with 32-bit OS with 2 MB RAM. It allowed the users to add more apps through software packages or obtain them through downloads.

b. Palm OS 

 It is another OS that emerged Psion’s rival in the PDA industry. Palm OS holds an edge over Psion concerning functionality in the PDA industry. Also, Palm OS has attained commercial success with a new generation of machines in 1996. The platform comes to you with a GUI touchscreen with essential apps accompanied by third-party apps, written in C/C++ language. It also gave access to the Linux platform before getting stopped.

c. Wireless Markup Language (WML) 

Developed by the WAP Forum, the Wireless Markup Language is an XML-designed language. The WML entered the late 90s & had a reputation of its lightweight and low bandwidths. It got stripped out as HTML consumed more processing power. The users felt the need to choose the WAP portal over logging on to the websites directly.

d. J2ME/JME 

Started as JSR 68, J2ME took over personal Java and evolved into numerous standards, thereby earning goodwill. The J2ME-based Personal Digital Assistant (PDA) and other handheld devices like set-top boxes with users’ profiles having configurations in different subsets. The mobile developers also use J2ME to design CDLC devices having the memory storage of 160KB to 512KB with minimum Java-class libraries that you need for running a virtual machine.

e. Symbian 

 Symbian got associated with the Psion EPOC operating system, which Symbian Ltd had developed. The company had a joint venture with Psion, Ericsson, Motorola, & Nokia. In 2009, over 250 million users used Symbian as a mobile application platform. Nokia had promoted Symbian OS through the S60 platform that developers used as a tool on almost all Nokia handsets. It also included Samsung, LG, Sony Ericsson, and others.

 History of Mobile Software Development

The beginning of Mobile Software Development

In the olden days, people relied on fixed landline phones. However, when a handheld device like cellular phones entered, people preferred to put the handset in their pocket.

When people went to meet their friends in a crowded place, tracking them became easy. Without the portable device, it was taking long hours to reunite.

Today, most of the places allow you to make the payment through phones. Below is the history of mobile software development.

  • Mobile software development started with the Motorola DynaTAC 8000X. It became the root cause for other cell phones, smartphones, and other mobile apps. Today, users depend on mobile phones for personal and professional interaction.
  • Initially, mobile users could use apps like calendars, calculators, and ringtone creators between the 1980s and 1990s. The cell phone manufacturers didn’t provide a flexible platform for the users.
  • The users looked for other features in a cellphone as they felt that mere calls were not enough. Nokia and other mobile software developers gave additional features to mobile phones like games.
  • Despite the simple apps, the games had attracted children more than other users. The strategy used by mobile companies attracted more customers.
  • When the users wanted to access the Internet over the phone, the cellular companies didn’t fail to satisfy users' requirements.
  • The users were initially happy, but owing to never-ending wants, the customers began to ask more. Also, they quickly found out the shortcomings of the handsets & their apps, which made the developers create more mobile apps.

Overview of Building Your First Mobile App

 Are you looking forward to developing your first mobile app? That sounds great! Every business would like to create and promote their app, products, and services with relevant information to the users at their fingertips. The mobile apps come to you in categories like:

  • Retail
  • Entertainment
  • Utility
  • Gaming
  •  News
  •  Lifestyle
  • And others

In the mobile application era, there would be more innovations that entertain the users and make their lives simple at the same time.

If you are not in the mobile application domain but has an innovative idea, you would instead go ahead with the development process. However, if you don't know how to go about it, here are the following guidelines.

1.   Come out with an innovative idea

If you have the vision to create a mobile app, you need to know your objective to present your product. The app you produce might provide a service or for entertaining people via movies, games, & many others. The users would think about the benefits they get for using your app. Ask yourself:

  1. Will the app make users' lives easier?
  2. Is the app's real value better than the previous versions in the existing apps?

Whatever problems you face, focus on solving those issues so you get the right solution.

2. Respond to your targeted audiences

Interact with the audiences for immediate feedback in the right direction. People may resist your idea at the initial stages. However, you should be a good listener and converse with the people who disagree with your vision and find out what they exactly need. Taking the customer feedback in the right sense boosts your confidence & enables you to convince them. Make a note of all your ideas and analyze why people would use your app. If you answer the questions, then you have validated your objective.

3. Do competition analysis

Check out for individuals & the other enterprises to find out who are into the same business & analyze their performance. You can find infinite ways of analyzing competitions. Suppose you consider the service value regarding content quality, user-friendliness, navigational controls, pricing, & availability. In that case, you need to analyze where your competitors have missed out so you can focus on capitalizing on those aspects.  Checking the keyword planner is an alternative to the quickest & simplest ways of analyzing the competition.

4. Sketch your ideas

After your interaction with the user & performing competition analysis, pen down what you want to build & prepare a sketch of the app framework. It would keep you focused on the next steps. Once you get your basics right, outlining the business model becomes easier.

5. Create a prototype

Once you pen down the imagination on your app, the next step would be to develop a minimum viable product. Decide the features that you wish to add to your app and make a prototype. The MVP enables you to ship your app quickly at lower costs. It also saves your time, money, and efforts in developing an unusable application. Creating a quick wireframe/prototype for your app would allow you to define your design's hierarchy and make your layout planning easier. You can get various prototyping tools online according to the sources.

6. Perform the validation

Validating an app provides you the evidence of demand and interest in your app. Give a presentation on your prototype and offer the competent answers to the users. If you have a product in your hands, you can talk about the salient features that your app provides to the users. Demonstrate or document the features and talk about the product details.

7. Decide the features you wish to provide the users

Based on the customer feedback, add the mobile app’s components to get the high audiences’ engagement. The user experience and the application vibes depend on the interface that you create. Prepare the features list you want to include in your mobile app, and know-how users should navigate the app from scratch to end. It also helps the developer to understand the client's expectations.

8. Hire your team

If you don't have the knowledge or don't have time to develop the app, hiring a developer or a designer would be the right step. Also, ensure that you employ suitable candidates for your organization. Interaction with the users enables you to know whether they believe in your app as much as you. You also need to register a developer account with concerned app stores for selling your app through their platform. You can register in the app store either as an individual or as a company.

9. Test your app

Testing is a phase in which you examine your application’s functionality, so you know the improvement areas. Technical Beta Testing makes it possible. You would also need the testers to check your app & provide you the report. Automated testing ensures that you have chosen the right testing team.

10.  Debug the errors, retest, and iterate

Once you find the bugs & errors, it would help you debug them before launch. If you skip testing, your app will get negative reviews, affecting your product to attain popularity.

11.   Integrate the analytics and required tools

It would be necessary to include analytics for tracking downloads, analysis, user behavior, engagement, & customer retention for your mobile app. You can get many tools to achieve that. However, it depends on the device that you select.

12.  Launch your app

You can launch your app on Google Play, App Store, Mobogenie, etc. It might take at least a week to get approval. However, in the meantime, you can make some changes to the app for immediate support. Generating speculations for your app, creating teasers, and collaborating with influential people features your app on their social media accounts, blogs, or websites.

The process is the same for the Android mobile app development and iOS app development lifecycle.

Software Development Kits (SDK)

What is the SDK?

SDK is the unique way of thinking about a software kit. When you assemble a car or a plane model, you would need different items to create an engineering or technology model.

A Software Development Kit (SDK) is a set of tools package with information that aids the developers to write programs in a specific programming language for an app or platform. The hardware and software vendors provide the developers with the required tools to build applications for a particular platform. The SDK might be identical to the execution of a program, using some interpreted languages.

If you have opted to build a mobile app in the development field, you need iOS SDK for iOS mobile apps. An Android apps developer would require an Android toolkit for creating Android applications. The SDK tools have three categories.

  • Programming & SDK operating systems like iOS, Android, and others
  • Maintenance of SDK apps
  • SDK marketing apps

Components of SDK

The Software Development Kit (SDK) includes the following redistributable components like:

  • SDK target platforms

The SDK is independent of different target platforms that cross-compile Cell Broadband Engines Architecture codes, X86, and X86_64 machines. 64-bit PowerPC and CBEA-compliant machines are the native development platforms. The two execution platforms consist of CBEA hardware and Full-System Simulator. You can also run the Full-System Simulator using CBEA hardware and debug the error codes.

  • SDK directories

The installation of SDK files in multiple directories depends on the host platform and file type. It gives you the description of SDK standards for guides that enables you to find SDK parts and extract the best from the SDK development environment.

  • RPMs

The RPM is a set of SDKs found in Red Hat Package Manager files, which you can install in any targeted platform. The RPMs depend on the Linux host you use as the target hardware platform with different user options.

  • SDK component descriptions

The SDK has a category of various components. Each developer uses the elements according to their expertise. Some members have a prototyping code, while other apps undergo complete testing with a warranty and a purchased license.

  • YUM Groups

Facilitates the RPM Groups to install multiple RPMs simultaneously and categorize the Pirut GUI.

  • Documentation

Helps the users to get familiar with one or more SDK and sample apps.

  • Libraries & Application Programming Interfaces (API)

These are the predefined codes that the developers use for performing the programming tasks on the platform.

  • Code Samples

Consists of the codes which the developers can edit as per client requirements.

  • Integrated Development Environment (IDE)

It is a visual editor that the developers use for designing the layout through graphical elements like text boxes and buttons. You can find these elements in all mobile software development kits. The tools also help the developers to debug, build, test, and re-run the applications.

Software Development Kits (SDK) Examples

A Software Development Kit (SDK) is a third-party designed chunk of pre-written code for desktop and mobile apps. Today, you can also get mobile apps that allow you to log in and use social logins like Facebook, Twitter, and Google. These companies provide the SDK to the developers with the required tools for building them in a mobile app. The examples of SDKs are:

User Login/Authentication

Notifications, Engagement, & Messaging

Advertising

A programming language is a set of instructions designed to control the hardware, machine, or computer. The programs also express algorithms and maintain the performance of a device. Presently, the developers implement thousands of programming languages for developing an application. Here are the different types of programming languages.

  • Procedural programming language

The developers use the procedural programming language to execute a set of statements to get the desired output. It allows you to use multiple variables, heavy loops like a loop, a do-while loop, and loops with other elements. The procedural programming language controls variables and returns values in a function.

  • Functional programming language

It stores the data and avoids extensive loops to avoid recursive functions. The available programming language focuses on the function's return values, side effects, and suggestions to store the data.

  • Object-oriented programming language

The world views the Object-oriented programming language as a group of objects, having internal and external data access. The Object-Oriented Programming Language has a structure of classes and objects that provide a specific problem. The principles of the OOPS concept is:

      • Encapsulation
      • Abstraction
      • Inheritance
      • And Polymorphism

The Object-Oriented Programming Language helps in reusability through inheritance and spreads the latest implementations without any significant changes.

  • Scripting programming language

It is a programming language interpreted and translated into a machine code during its execution. The scripting programming languages are procedural most of the time. The scripting languages possess the elements of object-oriented programming languages. However, they are not full-fledged and independent programming languages. Examples of scripting languages are Javascript, Python, Ruby, and others.

  • Logic programming language

Allows the programmers and the developers to make declarative statements and leaves them to the machine for execution. It employs restrictions on the hardware to run according to developers' requirements.

  • C-Language

It is a necessary and structured programming language exclusively used for game programming. C Language comprises additional packing of C++. The programmers implement C-Language for faster programs. You can also reuse C-Language to reuse C++ for increased performance.

  • C++ Language

As an object-oriented structured language, the programmers use C++ for large projects. You can collaborate with one program in different parts or individual work.

Mobile Application Development for beginners – Android & Apple

Do you want to learn mobile application development as a beginner? Whether you opt for Android mobile application development or Apple application development, there are specific steps you should follow to launch your mobile app successfully.

Roadmap for Beginners in Android App Development

Here are the following steps to learn Android App Development.

  • Download Android Studio

Before you download Android Studio, make sure that your device has enough storage. It would also help if you created a development environment so your desktop would support Android development goals. After installing the Android SDK, you can choose the tools required for developing an application. The Android Studio is as good as an Integrated Development Environment (IDE) that acts as an interface while coding. You can either use JAVA or Kotlin with the required tools for mobile application development. You also get access to various libraries and APIs from the Android Software Development Kit and access native functions to your operating system. The Android Studio also allows you to build an APK with a Gradle test through a virtual device and debug your code during execution.

  • Select an option new project

After installing Android Studio on your computer, here are the following steps:

  1. Click on File -> New -> New Project
  2. Choose the desired project template, defining the code and UI elements you want in the new application.

The Activity screen found in your application would be empty, barring from the raw file structure. The Basic Activity creates a starting screen for your app and allows you to add a button and hamburger menu to the top. These common elements in an Android app save your time and effort. If you opt for Empty Activity, it creates some files where you need not add too many additional codes. Select a name & package name for your new mobile app that impacts the audience. Android uses the package name as an internal reference that differs from other applications.  

  • Learn the appropriate programming language

If you are a beginner aspiring to become a mobile app developer, you need to master the programming languages like JAVA & XML in Android app development. Unless you attain proficiency & expertise in these programming languages, developing a mobile app would be a daunting task for you. The JAVA fundamentals comprise of:

  • Packages
  • Objects & Classes
  • Inheritance & interfaces
  • Strings, numbers, & generics
  • Collections
  • Concurrency

A thorough understanding of JAVA and XML enables you to build a robust, elegant, and efficient mobile app. Ensure that you have the minimum SDK:

  • Get familiar with the right development tools & the environment 

The mobile app developers primarily use JAVA for Android applications. However, Android would also demand XML for designing a full-fledged application. Once you master JAVA, XML would be easier for you to learn when coding your application.

  • Choose the layout for your app

The layout file slightly differs from Kotlin/JAVA file. The code shows the location of the layout file. It defines the look of the activity. Alternatively, you can also go to MyApplication -> app -> src -> res -> layout

  • Test your app

Testing the application is the next phase after developing an application. It is a phase where you can further improvise on the application apart from debugging the code. Once you install Android Studio, you have an Android system image with a Virtual Device Manager. You need an Android emulator set up where you can successfully execute the application. The Android Studio also allows you to change the settings of your virtual device and screen size. You can find the option in Tools -> AVD Manager and download new system images. However, ensure that your virtual machine would equal or exceed the minimum SDK at the initial stages.

  • Make an independent app

It’s the best way to learn the skills for developing Android application development. You need to have a track to edit the code right in front of you. It also helps you to become an innovative mobile app developer.

Apple mobile app development for beginners

are those servers that deal with transaction-based applications. Application servers take care of the coordination between end-users and the backend applications. Some of the popular application servers are XAMPP, WAMP, Apache Tomcat, IIS, and others.

Integrating Frontend & Backend in a Mobile App

If you are not a developer or are still in the learning process, it could be a daunting task to integrate frontend and backend.

For successful integration between the two, you would require to pile on frameworks, programming languages, APIs, and libraries that software engineers or developers utilize for building an application.

In this article, you will learn about the frontend, backend, and integration.

Frontend development: is the application designed for managing everything that users find in a browser or application. The developers take care of the look and feel of the website or application. It is a client-side development.

Backend development

Backend development is all about the server-side programming that contains the code required to build the database, server, and application. You would need a proper system configuration for the database to API integrations for setting up the server-side technologies to make the website send the notification to the backend web developer.

Relationship and integration of frontend and backend

The relationship between frontend and backend is that of a client and a cook in a restaurant.

In the frontend and backend, the user feeds the data and hits the Submit button. The server-side manages the data or the user requests through their clicks. The frontend scripts pass the data to the server-side, which returns the data to the frontend.

How does backend architecture work?

A typical backend contains server databases, API, and operating systems that store the users’ request data. However, server-side scripting is a type of backend application that works on various servers like cloud-based servers and data warehouses.

The breakup of the backend application

The backend has four components like database server, software, and operating system. Here is a detailed explanation of these components.

  • Servers

The mobile app’s backend server shares the resources with the network required for operating as a mobile app housing platform. The resource-sharing includes data encryption, security, and miscellaneous web services. These servers get the provision to house various apps through virtualization or containerization, paving the way for the service provider to the operating system.  

  • Database

It not only stores the data but also makes the website application dynamic. Whenever the user places the query from an app, the database accepts the request, fetches the information & returns it to the end-user.

  • Middleware

It is an application that works on a server and mediates between frontend & backend applications. Middleware helps in connecting between the client & a server in layers like business and presentation.

Conclusion:

To make the frontend & backend work together, you need to configure the system, depending on the programming language & database you use.

User Authentication-Authorization

What is User Authentication?

  • User authentication verifies the credentials of an active human-to-machine transfer required for confirming authenticity.
  • The server uses authentication when there is a need to know whether the concerned person has logged in to access their site.
  • The client uses authentication when they want to know the type of server system.
  • The server entails authentication via username & password.
  •  Now, the server uses other authentication ways like cards, retina scans, voice recognition, & fingerprints.
  • Client authentication involves the server in giving certificates through trusted sources like Verisign and others.
  • It does not decide the task that an individual has to perform or what files they can access.
  • The user authentication began with a combination of simple id & password. Now, technology had advanced so much that it had tightened the authentication process, thereby improving security. You can also call that encapsulation, in other words.
  • It authorizes the interaction between users & systems through wired & wireless networks to access the internet & networked-systems & resources.

What is Authorization?

  • It is a process in which the server decides to grant permission to the client to permit them to use the resources of accessing their files.
  • User authentication and authorization go hand-in-hand in which you might require a password in some cases.

Hence, the user authentication-authorization is all about data encryption, which would be a barrier for unauthorized persons accessing your data.

The purpose of user authentication-authorization is to maintain confidentiality.

Techniques Used for Authentication & Authorization

As an IAM administrator, you need to understand how user authentication-authorization works and the difference between them.

  • In authentication, the organization allows all the employees to access their workplace systems. However, in authorization, only the designated employees or system administrator can access the gated data.
  • Implementation of authentication, accompanied by providing authorization to a reliable person, would protect the organization from data theft.

Popular Techniques for Authentication

  • Password-based authentication 

It is one of the simplest methods of authentication. It would need a password to verify the credentials of the user. 

  • Passwordless authentication

In this scenario, the system would send the OTP or magic link to the users’ registered email address or mobile number.

  • 2FA/MFA

It would take more than one security level, such as personal identification number and security questions, to grant access to the system after confirming the user’s identity.

  • Single Sign-on

It provides the users for accessing multiple applications with the same credentials. 

  • Social authentication

Performs verification and authentication of the users with existing credentials via social networking platforms.

Techniques Used for Authorization.

  • Role-based access controls: 

It’s one of the techniques which you can implement from system-to-system privilege management.

  • JSON web token: 

JSON web token is an open standard that allows you to securely transmit the data between the authorized parties & individuals who use public/private key pairs.

  • SAML: 

Termed as a standard Single Sign-On format, the exchange of authenticity occurs via digitally-signed XML documents.

  • OpenID authorization: 

It verifies the identity of the user according to the server’s authentication.

  • OAuth: 

It enables the API for accessing and authenticating the system or resource.

Data Services

Creating a data-driven Mobile App Development

Data plays a vital role in the world of technology, which should be taken into the first phase while developing a mobile app. The purpose of maintaining a database is to deal with a large amount of data efficiently. Furthermore, maintaining data security has become the primary concern before creating a mobile application.

The data resource is the determinant of successive mobile applications or web applications with many engaging users.

Overall, the user would need a highly engaging and high-performance application that would give the desired results to their business.

How do you create a data-driven mobile application?

The following are the steps to create a data-driven mobile application.

  • Use designing and development skills with data-driven codes

A data-driven programming language comprises a well-structured pattern matching that would generate desired results. The programming model data restricts itself in controlling the flow of the program. However, you can control the program's flow through different data sets, which prevents data coupling & functionality. Data-driven programming enables you to build high-performance mobile apps via user low tolerance performance issues.

  • Analyze your needs and be ready to iterate

When you scale your mobile app according to the traffic or a large audience & concentrate on deploying your application on multiple platforms. It would help you create the mobile app database within a low time-frame with minimal coding. The data-driven approach also helps you build different mobile applications & reuse the back-end components, capturing & refining the data.

Mobile App Databases that Developers Use to Build an Application

Some of the popular databases that developers use to build Android and iPhone apps are:

1. MySQL

is an open-source and multi-threaded database that developers use to develop a mobile or website application.

2. PostgreSQL

Apart from being a powerful and open-source database, PostgreSQL is an object-based and relational database you can design based on user requirements.

3. Redis 

It's a database that does not need high maintenance, key, or store value that you use for data caching in a mobile app.

4. MongoDB 

Derived from the JSON document, MongoDB is a schemaless database, unlike other databases. The database has become popular owing to its flexibility and scalability.

Note: The mobile app database does not limit only to the above. You can find other databases like Memcached, Cassandra, SQLite, InfluxDB, RethinkDB, RiakDB, CouchDB, and more.

Mobile App Development Security

What do you mean by mobile app development security?

Mobile application security is the measure that you take for ensuring the security of your mobile app that meets the following criteria.

  • The security features that you insert and implement before the application launch.
  • Make sure that your app abides by all security regulations.
  • There would be a need for you to test and monitor your app for security issues continuously.
  • It should address the security issues that pop up.

Why do you need security for your mobile app?

In the present era, mobile app security is a part of the development and maintenance process. Though Cyber Security has put stringent laws against data theft & hacking, these practices keep increasing in large numbers. Over 60% of the companies worldwide complain about cyber-attacks on their businesses, piling up their table with complaints. Instead of approaching them after you had incurred a loss, why not add security to your mobile app to protect your data from the users or hackers? Here are some of the reasons why Security add-on layers are essential.

  1. It helps you to address the issues in a mobile application.
  2. It enables you to reduce the possible threats in a mobile application.

Common & Potential Mobile Application Threats

If you are looking forward to implementing the proper security protocols for your mobile app, you need to know the practical threats your application would face after the launch. Once you understand the dangers, it would give you a crystalized idea to mitigate the security risks and plan how to counter those risks. Your app could encounter potential hazards like:

  • Unsecure Wi-Fi

Today, people use their mobile phones to go online, especially when they are not home. When they go to places like coffee shops, they will sign on to open the network via free Wi-Fi. However, on the other token, such networks may not provide data security, allowing hackers to take advantage of unsecured networks and access confidential and sensitive data directly from phones or apps connected to those networks.

  • Malicious Code

Many users download the apps either from Apple Store or Google Play Store, where the app developers have to adhere to the guidelines for getting their apps listed. You would also find many users who download the apps from a third-party website other than Apple Stores or Google Play Store. Such apps might have malicious code, which is a huge red flag for your device as the hackers would get an opportunity to copy the popular applications & offer them to third-party websites. Once the users download those apps, it would give room to the hackers to access your data.

  • Vulnerable Operating System

Android & iOS are those operating systems that continuously notify you about potential security risks that hackers might exploit. The updates that you get through notifications comprises security patches or upgrades that indicate possible threats. Hence, there’s a need for mobile users to update their OS as & when they get the updates. An outdated OS would be more susceptible to security issues.

  • Data Leaks

The user experience personalized through the application’s user data gets stored on remote servers. It would give hackers access to all information by gaining them from remote servers, which leads to insecure storage and data leakage.

  • Cryptography Issues

Cryptography helps in data confidentiality for Android as well as iOS. However, both phones work differently. The iOS would verify the digital signature of an app from a reliable source before decrypting it. The Android confirms the digital signature of an application though it doesn’t prove the signer’s trustworthiness. That’s the reason for a user to download the apps from official sources. If a developer does not use encryption would expose the users to possible data theft.

Best Practices for Mobile Application Development Security

Now that you have a better understanding of potential security threats, it would help you build the app that would focus on building a great security plan for your mobile app. Here are some of the best steps that you can implement before and after launching your mobile app.

  • Conduct digital security training

Educate and train your team on potential security risks that mobile apps can face. It would give them a better understanding of mobile security threats, which helps them mitigate against those risks.

  • Always make a point to download from a trusted source

Apart from designing a mobile app, it would be equally vital for you to make sure that users would download the app only from reliable sources. If a customer prepares the same app from an untrusted source, they will hold you responsible when someone hacks your data, which would lead to losing your customers. Hence, you need to warn your customers against those sources and clarify that your apps are available in sources like Google Play Store or Apple Store.

  • Secure your application’s code and backend

Cyber attackers or hackers always search for bugs or loopholes in your application’s code with reverse engineering. It would be a cakewalk for them to break into your app on finding the bugs or vulnerabilities. In the case of the backend, the code runs on your server & has your database. So, you need to secure your code as well as a backend for data protection.

  • Always set a procedure for secure identification authentication & authorization

Insufficient authentication mechanisms are prone to mobile app vulnerabilities. You need to follow the procedure for identification, authentication, and empowerment to restrict the application’s access to your developers & users. Some apps have weak or apparent passwords, which would pave the way for the hackers to figure out the user’s password & hack your account in the app. The developers implement a multi-factor authentication code through email or OTP login as a practice.

  • Secure data storage

Data storage plays a vital role in securing your data from unauthorized users. Data encryption performs the task of protecting the data collected through your app, thereby making it a daunting task for the cybercriminals to read the data even if they find a way to access them.

  • Make the policies for mobile encryption

Encryption policy in a mobile phone protects your data. The developers design different encryption types like pin code, pattern password, biometric fingerprints, and others to select any of them to protect the data.

  • Test the application before launch

When you test your application for security vulnerabilities, it will give you an idea to fix them. It would be a need for you to test your application at every stage of development. Even after the launch, please do not leave it at that. Instead, it would help if you keep improvising the app to notify the users to download the updates. The professional application developers would also run penetration tests like white box testing, black-box testing once or twice a year. The tests imitate the possible cyberattacks to identify loopholes like unencrypted passwords, low-security settings, and other unknown problems.

 Mobile App Security Features

Features to include to reduce loopholes for hackers/unauthorized users

The mobile industry first began with an essential handset, which was very expensive. However, mobile buyers increased by leaps and bounds when mobile phone prices declined with the growing technology. The users see the handset as having more features than their handsets, and they would focus on the functions, features, and aesthetics. However, not many would have the awareness about mobile app security.  Even a speck of vulnerability would drain away from the hard work and efforts. And the money the clients had invested would go for a toss. Hence, while creating a mobile app, there would be a need for you to consider the security aspect as well. Here are some of the features you need to include in mobile app security.

1. Single Sign-on for better app security

Are you looking for a device with more security? If yes, then a handset with a Single Sign-on would be ideal for you! A Single Sign-on (SSO) would offer you more than increased security and improve user-friendliness. Whatever credentials you use for accessing a platform, you can use them on other popular platforms like Google, Facebook, and other apps & websites that use OpenID.

2. Add biometric authentication

Because of bypassing biometric challenges, technology has become popular. Apple’s iPhone, the first mainstream consumer device, had featured the users with this authentication. Biometric authentication type of authentication that scans the unique part of the body for verification purposes. Apart from the fingerprint biometric authentication, the technology comes to you with other foolproof forms like:

      1. IRIS Scan
      2.  Recognition of voice
      3. Facial Mapping and
      4. Recognition of signature

Biometric authentication is one of the most reliable security providers for mobile apps. It would be highly challenging for an unauthorized person to steal the IRIS or other person or fingerprints.

1.Include 2-step authentication

You can also term 2-step authentication as two-factor authentication. Now, 2FA has become one of the most common rights, from social media apps to e-commerce apps. It would only require a simple login process. You can do 2FA in some of the ways like:

  1. Username and Password – Entering the security code or security token sent you your mobile phone when logging in.
  2. Username & Password - Entering the security code or security token sent to your email address.
  3. Answering a security question
  4. Verifying the login on another connected & verified device
  5. Verifying the identity via biometric authentication
  • Mobile app security for financial transactions

Transaction security like transaction password is the way to safeguard the transactions like purchase, sale, stock trade, & others from fraud cases, cyber-attacks, & other vulnerability exploitations. Transaction security comprises of the following steps:

      1. 2FA or biometric authentication that verifies user identity before the transaction.
      2. Add data encryption to the most vulnerable transaction phases.
      3. Provide the encryption of data, like financial information & funding sources.
      4. Usage of advanced SSL technology while communicating with a server.
      5. Insertion of biometric authentication for every transaction
      6. Promote automatic logout after a specific time of inactivity

Note: You need to add a lot more security features like security vulnerabilities like IoT, Disable Debug Code, Sandbox, and more.

Conducting a mobile penetration would be essential before releasing your app for production purposes.

What do you understand by application security?

Application Security describes the process of making them secure by testing, debugging, and tightening the app's security at the development phase.  The purpose of application security is to prevent data or code within the application from the hijackers. It also involves the systems and approaches to protect the applications even at its post-release.

Pros of application security

Application security plays a critical role in developing an application. Today, you can find many application vendors in the market over various networks connected to the cloud. However, many enterprises come across applications vulnerable to security threats and breaches. Now the companies not only demand security at the network level but also within the applications. Rightly so, as the hackers again go after the apps with more attacks than before. Following are the advantages and disadvantages that you can find in application security.

1. Reduces the risk

The application security protects the data from unauthorized users and third-parties.

2. Protects your brand image

The application security prevents data leakage via data encryption, which the customers and users would appreciate.

3. It helps you build and safeguard customer confidence

A happy or satisfied customer would write good reviews about your product. A positive customer experience would encourage the buyers to order for your applications.

4. Provides data security

Application security offers data protection to the developers and the end-users.

5. Increases the clients, investors, and lenders’ trust

The app security enables you to mitigate the risk & win the clients, investors, & lenders’ confidence.

Disadvantages of application security

a. Bugs

Though the apps run according to the expectations, you would still find bugs in various forms. They may be a minor bug like incorrect coding of print output or improperly-formatted error message and others. However, they can also prevent the user from login into their page, leading to complete system failure. Some of the errors would indicate security vulnerability on which the hackers leverage that loophole.

b. Broken authentication

Authentication is all about the verification process that ascertains the user's credentials. However, an incorrectly-configured software would expose a high vulnerability level, which gives the attacker an advantage in compromising with the passwords or session tokens of all users. It also goes to the extent of taking over the users' accounts for assuming their identity.

c.  Exposure to sensitive data

Some applications don't protect sensitive data like health information, financial data, and essential data like usernames and passwords, which would provide information to hackers. The attackers would get an opportunity to commit frauds like stealing people's identities and misusing their credentials. Hence, sensitive data would require ultra-protection like data encryption.

Mobile App Testing

What is the Definition of Mobile App Testing?

A group of user segments presents themselves with an in-app experience for determining the needful action from them or have a better impact on critical metrics.

When it comes to the mobile app, you need to figure out what would work well and optimize them according to your desired metrics to give your unlimited business opportunities.

Benefits of Mobile Application Testing

Debugging of a Mobile App

Mobile App Debugging Introduction

In general terms, Debugging is about the process of spotting out the program errors, bugs, or any other abnormalities and fixing them. The developers apply the same concept to debugging a mobile app. Debugging plays the most critical role in development. Its purpose is to ensure that your program or app is free from all errors that enable the application to execute according to the client's specification set.

Types of Errors in Mobile Application

When the developers come with creating a mobile app, they would research the code or use the logic. However, the real test comes only at the time of executing a program. The main errors in a mobile app are compilation errors and runtime errors. The compilation error occurs at the time of execution. In contrast, the runtime error occurs on the successful implementation of a program, but it does not run as per specifications. Both of them have different subcategories.

  • Syntax errors

Just as human language has specific guidelines for forming sentences, in the same way, programming languages also have certain norms in grammar, which you call syntax. As the devices cannot think by themselves, they can't ignore errors. The code would not run even if there is a minor error. Debugging is the only solution that you have for the smooth execution of a mobile app.

  • Logical errors

In a logical fallacy, you won't find any errors when you compile. However, you don't get the expected results. These issues occur very often at the time of developing a mobile app. As logical errors are difficult to track, the only solution for you is to locate the mistake through debugging tools or commenting on the codes to fix the error. However, it would also be a tedious process. Hence, you need to check the requirements before performing the task.

  • Compilation errors

In specific programming languages, your program would have to undergo a compilation process. The error occurs if the computer is unable to translate the code to a lower-level. The error may have syntax errors or missing parenthesis. As the compilation error specifies the line number, you would have to go to that line & fix that error.

  • Runtime errors

Logical error is an example of runtime error, which runs correctly on the machine, but there would be a different configuration. The runtime errors are very much frustrating as they would directly affect the end-user. These errors occur when you are in front of the system and working on a mobile application. However, you can overcome these errors if you have reliable error reporting to capture runtime errors.

Android app debugging, iOS App Debugging, and Out system provides you with different debugging tools to make your app run according to expectations.
