Android libraries are a set of implementations of behavior that are written in a programming language with a well-defined interface.

These libraries include documentation, configuration data, help data, message templates, pre-written code and subroutines, values, classes to name a few.

These libraries serve as a tool and offer necessary codes that are pre-written helping developers craft scalable mobile app development. In this article, explore the top 15 Android libraries for great Android app development.

Compiled List of Top 15 Android Libraries for Developers

1. Dagger 2

While many Android libraries have one or more limitations and majorly rely on XML, Dagger 2 is entirely dependent on Java processors along with this compile-time to estimate and analyze dependencies. Also, it simplifies access to shared instances. The Dagger 2 generated code is very relatively easy to read and debug.

2. Retrofit

Making a network request made easier by the Retrofit Library! Being known as a type-safe REST client, it smartly maps an API into a client interface with the help of annotations. With this library, developers can enjoy rich features including manipulating endpoints and headers, adding a request body and query parameters, selecting request methods etc.

3. Picasso

As the name suggests, Picasso is a highly popular image loader library used for loading and caching images. This is most used in the apps that deal with images. Examples may include social apps, photo editing apps, shopping apps etc.

4. Glide

Managed by Bumptech, Glide is another sound image loader library recommended by Google. The framework offers multiple functionalities to developers like decoding, fetching, resizing images, video calls, animated GIFs etc. The library can be plugged into many different stacks because of its highly flexible API.

5. Zxing

Zxing comes under scanning libraries and is highly useful for indexing the millions of barcodes. Integrated with Google Book Search and Google Product, the library helps developers get additional support for the 2D, 1D industrial, and 1D product bar codes.

6. CAMView

Another barcode scanner that enables easy access to the camera with a QRscanner! CAMView offers multiple features like immediate access to preview/live video, scanning barcodes, and live processing via camera. This library has an added advantage than Zxing.

7. Bubble Navigation

It is a lightweight library that offers varied options to the developers. With a unique approach to navigation, it creates beautiful navigation bars with many custom options in it. 

8. Espresso

It is a testing library that helps developers for user interfaces tests for Android mobile app. It helps you in identifying whether Text View’s text matches with other text. Espresso can be used for writing reliable, beautiful and concise test cases for your Android UI.

9. Mixpanel

An excellent paid library for analytics! While Google Analytics comes for free, this paid framework offers the users certain basic functionalities free of cost but some are payable. The library will track the events and can be used to know the entire user journey to the funnel.

10. Gravity View

Gravity view is a new concept in Android libraries used for image tilting using sensors. This library utilizes the motion sensors of Android devices, allowing users to perform certain functions by rotating their device.

11. MP Android Chart

This library is used for drawing and graphic design. It supports radar, line, bar, bubble, and pie and is also useful for scaling, animation, and dragging.

12. ExoPlayer 

An Android media player library developed by Google! It plays audio and video with customizable features. ExoPlayer is one of the most useful libraries in mobile application development.

13. Timber

This library aids you to learn and debug fast. Timber has a lot of potential and one can easily make logs without tagging the logs manually. The logs know their classes, and the tags come automatically.

14. Crashlytics

Crashlytics is used for reporting the app crashes. It offers a detailed report on all crashes and also reveals the issues that should be fixed on priority basis. The library can be implemented quickly and does not hold extra data causing app to slow. It is a must to have a library to eliminate the chances of app crash in between. 

15. Robolectric

Robolectric offers reliable and fast unit tests. It can handle views, resource loading’s inflation, and other things. The tests run within a sandbox and can also be well isolated from their neighbors. Robolelectric can stimulate the Android SDK’s for a test eliminating the need for additional frameworks.

Conclusion

I hope you liked this compilation of some of the most useful Android libraries of 2021. These libraries offer great support to Android app developers and let them develop a robust and responsive mobile app that is highly efficient & growth-oriented.
