Android has been among the leading mobile operating systems worldwide in January 2021, occupying the mobile OS market with 71.93 percent shares. It's no wonder; android mobile application development is highly in demand. Android app development takes more time than iOS development because of the large number of android devices.  Whether you are a novice developer or experienced one, you know that performing a simplest task can be complicated sometimes. Luckily, there are many android frameworks, SDKs (Software Development Kits), and Libraries that can help you reduce the complexity of development, increase the speed of development and optimize your application's performance. So, here are some of the essential Android Libraries, SDKs, and Frameworks that will accelerate your android application development.

Top Frameworks to Use for Android Application Development

There are many frameworks available for Android Application Development, which also includes many cross-platform frameworks like Flutter and React Native. Let's talk about some of the popular frameworks out there.


Kotlin is a programming language that has gained outstanding popularity and interest among developers. According to Google's Google's #IO17 announcement, Kotlin has become an official language for Android apps. Its clean language-design and powerful features make it popular among developers. Kotlin aims to bring together the features of programming languages that have proven beneficial for large-scale projects.  Even though developers can use Kotlin anywhere Java is used, it is primarily used in android app development. Many companies like Google, Trello/Atlassian, Pinterest, Kickstarter, and Uber are using Kotlin for their benefits. Some of its benefits include writing less code, easy adoption, fully compatible with Java, and imposes no runtime overhead.  Kotlin being more fault-proof, the app developed through Kotlin will be easier and cheaper to maintain. Kotlin also helps you in faster development as it is briefer. Fewer lines of code mean less time spent on coding and less money spent on development. Isn'tIsn't this great? You can also transform your app from one platform to another if required.


Flutter is an open-source mobile app SDK developed by Google in 2017. Dart is the language in which Flutter applications are developed. It is quite a simple language to start with and a clear language intended by Google to replace JavaScript. Since Flutter has recently entered the list of cross-platform app development frameworks, the great ideas have caused it to catch on among the developers.  Although there are many successful frameworks in the industry, many big companies like The Google Ads app, Alibaba, The eBay Motors app, etc. that are choosing Flutter for android application development. Even Though Flutter is quite capable, it is still new in the industry and continuously updating its features. The most significant benefit of Flutter for most businesses is hiring only one team for both iOS and Android Platforms. Flutter allows developers to build stunning and attractive interfaces. However, there are many other benefits of Flutter Framework such as high productivity, fast and simple development, excellent performance, compatibility, and most importantly, Flutter is open-source. 

3.React Native

React Native is among the most popular JavaScript libraries used to develop both Android and iOS applications. React Native can help you develop native applications for all devices and operating systems. It's an open-source, cross-platform framework that is developed by Facebook. Using React Native, developers can develop high-performance apps with faster deployment time in less duration.  It uses JavaScript and helps in developing rich, responsive, and unique apps. In 2021, React Native has gained popularity in the top mobile app development frameworks. React Native provides a set of unbelievable native components like Views, Text, etc. It supports JavaScript, which is crucial for full-stack development. React Native offers some outstanding features like low code, support for third-party libraries, short development time, live reload, and declarative API for predictive UPI. These are some of the features that make many famous companies like Facebook, SoundCloud, Instagram, Ubereats, and Airbnb use React Native. By migrating to React Native, you'll find a simple architecture, increased app performance, and also you will be easily able to control the builds.


Ionic is an entirely free and open-source framework developed with Angular and Apache Cordova. It allows the developers to develop apps for iOS, Windows, and Android. Ionic is used to build cross-platform mobile applications for high mobile performance. Mobile App Developers use Ionic Framework for powerful and fully-featured mobile application development. One of the most significant advantages of the Ionic Framework is that developers can use several UI elements in their application development. The UI elements like ListViews, Forms, filters, action sheets, navigation menus, and tab bars help developers develop high-performance, robust, and responsive mobile applications.  Ionic is a feature-rich cross-platform development framework. It can prove to be the best framework if the developer is well-experienced with HTML, JavaScript, or CSS. There are various features in Ionic Framework like Cordova Plugin, easy and fast development, JavaScript Components, complete control over app building, and much more. These features make Ionic one of the best frameworks for cross-platform development.
