Top Android App Development Frameworks, SDKs, and Libraries in 2021

Android App Development Frameworks

With new waves of the coronavirus disrupting businesses again, digital solutions continue to play crucial roles. Mobile apps emerged as one of the most crucial tools early in the pandemic. It prompted unprecedented demands for Android app development and other digital technologies. Businesses that swiftly adopted digitization last year are better prepared to deal with the second wave of the pandemic.

While small and medium enterprises rushed to digitally deal with the disruptions, big corporations, too, scaled up their digital systems. With offerings like Flutter app development services, business owners have been able to rapidly cope with shifting market conditions.

But what are the leading technologies driving this new wave of transformations? That’s what this blog post delves deeper into so you can make informed decisions. Let’s dive in and find out the best mobile app solutions for your business.

Best Android App Development Frameworks

In markets like India, the demands for Android app development are still higher than iOS. That means this new wave of digitization has further made Android apps even more popular. Flutter app development services and other Android offerings are seeing rapid evolutions. And all of this, the role of app development frameworks has become more crucial than ever.


Flutter is an open-source, cross-platform software Android app development framework. Developed and maintained by Google, this framework is designed to make efficient Android and cross-platform apps. Flutter can use a single codebase and uses a Dart language. It also provides detailed documentation for every development project.

Flutter’s ability to facilitate both iOS and Android app development from a single source code makes it immensely popular among app makers. Flutter has continually made UI enhancements to make apps more beautiful. Such UI enhancements include support for autofill, new mouse cursor support, a new responsive license page, among others.


Kotlin is a statically typed, general-purpose programming language for app development. It relies on the Java Virtual Machine and JavaScript. With Kotlin app development, developers can significantly improve the productivity of their work. Kotlin’s framework dramatically improves the coding experience by offering capabilities like interoperability. One of the major areas of Kotlin’s focus is to enable mixed-language projects for app development.

Using Kotlin with Java can significantly boost both the quality and efficiency of mobile app developers. Kotlin’s capabilities ensure that developers get improved syntax along with concise codes and better abstractions.

React Native

React Native is one of the top mobile app development platforms for developers around the world. It “combines the best parts of native development with React.” It provides a comprehensive set of platform-agnostic native components like view, text, and image. As you know, these are the building blocks of an app’s UI.

React Native’s cross-platform capabilities enable app developers to build apps that run seamlessly on iOS and Android alike. You can use React Native’s pre-built JavaScript libraries to power your project. It allows you to avoid repetitively building code blocks for different platform-specific apps.

Android Development Libraries

No matter what kind of app development project you talk about, libraries always play crucial roles. Below are some of the most widely used Android app development libraries.

Dependency Injection Libraries

Dependency injection is a programming technique that allows programmers to make a class independent of dependencies.

Dagger 2

The Dagger 2 library relies on Java annotation processors. It estimates compile time by checking dependencies. Dagger 2 a static library that covers extensive areas of Android programming, providing solutions to multiple pain points. It’s one of the most widely used Android frameworks for open-source projects. The library prompts performance penalties during startup or validation issues at runtime.

Networking Libraries

Networking enables developers to analyze the communication process among different systems. Networking libraries are, therefore, crucial to sharing information and resources.


Retrofit is known for its developer-friendly features and functionalities. The library depends on modeling over a base URL. You can even make interfaces return the entities from REST endpoints. Retrofit uses annotations for mapping an API into the client’s interface dealing with APIs, creating massive amounts of data. That changes with Retrofit.

Database Management Libraries

Android developers need reliable libraries to manage data seamlessly across platforms. Here’s one.


Room is an official Android app development framework created by Google. It allows you to build offline Android apps. Room is built on the SQL library, which enables app developers to convert raw data into an organized database Room aims to deal with the challenges faced in traditional database management processes. Such challenges include code redundancy and SQL management in complex databases.

Debugging Libraries

Having the right libraries makes the debugging process faster and more reliable. Here is one of the best debugging libraries for Android.


Stetho is a high-performance debugging library for native Android app development projects. You could use this library for network inspection, and database inspection. Additionally, the library also gives you access to the Chrome Developers Tools. It also has an optional dump app functionality. Using Stetho, you can create an efficient command-line interface for your Android app.

Wrapping Up

Frameworks, SDKs, and libraries will likely play even more crucial roles with the competition intensifying in the app market. With never app makers springing up at an unprecedented rate, the need for expertise is getting increasingly critical. And that’s where the use of the right tools and techniques comes into the picture. Only experienced professional developers know which tool is best suited for which project.
