  • Android libraries ensure consistency and stability in the codebase, making it easier to maintain and scale the application over time.
  • There are several resources available for Android libraries and the vast community support makes it easier to find the solutions
  • According to a report by Statista, the number of apps available in the Google Play Store reached 2.87 million in August 2021

Top 15 Android Libraries To Use For App Development

Top 15 Android Libraries To Use For App Development

1. Glide

Glide is one of the best image libraries proving smooth and quick image loading. Be it from an internal or external source, you can fetch, decode and display images in a much more convenient way.

The library is highly recommended by Google and is preferred by developers. Glide smoothens the scrolling process and makes using the application easy to use.

How to use Glide?

  • Start by adding Glide to dependencies in the build.gradle
  • Design a comprehensive layout file for your project
  • You can load the images into ImageView with Glide with the help of a fragment class
  • The next step will be adding the given fragment to the activity through Navigation Component
  • After this, add internet permission to the Android Manifest
  • The last step is to bring Gradle into sync and then your Glide is ready for loading images smoothly

2. Picasso

Created by Square, Picasso is an amazing image library for Android. It helps to download and save images optimally. With Picasso, you can receive and download images with compressed size and the same quality.

It is good at handling download cancellation, image transformation, automating caching, etc. Some of its features are similar to Glide.

How to use Picasso?

  • Start with adding a new project in Android Studio
  • Add the Picasso dependency to your build.gradle file
  • Next, you need to incorporate an ImageView layout into the activity.xml file
  • Now create the ImageView instance in the layout in Mainactivity.java
  • Hence, your Picasso is ready to download and store the images

3. ExoPlayer

ExoPlayer is one of the best media-playing android libraries developed by Google. It supports playing videos and audio both online and offline. Exoplayer works better than Android’s MediaPlayer API as it uses advanced features like Dash and SmoothStreaming playbacks. Also, with this library, you can customize this one and update it on the PlayStore.

How to use ExoPlayer?

  • Start by adding ExoPlayer’s dependency to your project
  • Secondly, make a “SimpleExoPlayer” instance
  • Connect it to the View
  • Check by adding a MediaItem to the player
  • If it plays well, release the player

4. Retrofit

It is one of the best android network libraries developed by Google to send and receive HTTP requests. Retrofit is a type-fast REST client for Android and makes it easier for developers to work with HTTP requests.

It can work with multiple types of data formats, request, and response caching. The ability to work with custom converters makes it a more powerful and preferred library for Android development.

It also provides an easy API to handle error cases and aids with multiple callback methods for success and failure.

How to use Retrofit?

  • Add Retrofit dependency on your build.gradle file
  • Internet Permission is to be added to Android Manifest for enabling network transactions
  • Parse the JSON data by adding the POJO model
  • Now, generate a Retrofit instance
  • Add multiple API interfaces to support different network transactions
  • Generate your data list and launch your app

5. Dagger2

Dagger2 is a compile-time framework that helps developers to simplify the complexity of Android development codes. It injects code dependencies into the app by using annotations and code generation. This provides the clean and modular architecture of an Android application making a heavy application run smoothly.

How to use Dagger2?

  • Add the latest version of Dagger2 to your project build.gradle file
  • Make a list of dependencies you want to inject into the app’s components
  • Create a Dagger2 module to add the dependencies
  • Create a Dagger2 component to link the module and the injection target.
  • Annotate the injection target for the dependencies
  • Inject the dependencies in the target by creating a component instance

6. Butterknife

ButterKnife is a view-binding Android Library developed by Jake Wharton of Square. Similar to Dagger2, it reduced the boilerplate code by using annotations. With ButterKnife, the need for findViewbyId() is reduced which helps to bind Android views to the code easily. As the code simplifies, it can be easily altered and maintained as needed.

How to use ButterKnife?

  • Add ButterKnife dependency to your Android project
  • Make a list of views you want to bind with the code
  • Annotate the views with the appropriate bind view annotation
  • Now use the ButterKnife method to bind the annotated views

7. Android Databinding Library

Android Databinding Library is provided by Google. It helps to bind UI components to the data sources so that when the data changes, the updates are automatically available in the UI. This library needs the version of Android Studio 1.3 to operate. Unlike ButterKnife and Dagger2, it does not use annotations.

How to use Android Databinding?

  • Add Data Binding in your android project’s build.gradle file and your layout XML file
  • Access the binding object to your activity
  • Finally, Bind data to your UI elements

8. RxJava2 & RxAndroid

Both of these libraries provide reactive programming for building high-performance, efficient Android applications. RxJava provides support for Java reactive programming. It can customize data streams and supports concurrency and multithreading as well.

While RxAndroid provides features and utilities for RxJava2. It helps developers to work easily with different threads, and manage asynchronous tasks and errors.

How to use RxJava2 & RxAndroid

  • Add both dependencies to your Android Project
  • Create an observable that emits a sequence of data
  • For receiving the data, you need to subscribe to this observable
  • To run different threads, use RxAndroid
  • Use the RxJava2 operator to transform the data streams

9. JUnit

With the JUnit testing library, developers can create, run and debug tests on their android applications with ease. JUnit is a framework specifically for Java projects.
