These libraries consisted of Documentation, Templates, Codes, Values, Categories, Configuration data.

In a real sense, these libraries have pre-written necessary codes that help developers to develop a scalable & efficient app in less time. 

12 best Android libraries for scalable Android App Development: 

  1. Dagger 2

Many Android libraries for developers have a major dependency on XML and have some limitations. On the other hand, Dagger 2 relies on Java processors along with compile-time to estimate and analyze dependencies. Furthermore, it simplifies access to shared instances. On the developer’s end, the Dagger 2 generated code is easy to read and debug.

  1. Gravity View

Gravity is the new concept in Android libraries used for image titling through sensors. It harnesses the motion sensors of Android devices and allows users to perform multiple functions of rotating their devices.

  1. Timber

The library empowers developers to debug fast. Apart from fast debugging, one can make logs without tagging the logs manually. It goes as tags come automatically when the logs know their classes. 

  1. Crashlytics 

It is widely used for reporting app crashes. It delivers a detailed report on all crashes and prioritizes the fixation of issues. Through it, the library can be implemented quickly, and it eliminates the possibility of an app crash.


We hope this compilation of the 12 best Android libraries 2021 will help you to choose the best one for a particular purpose.
