Top 15 Android Libraries for App Development

android app libraries

Android libraries and frameworks are a set of execution of code written in programming languages having a well-developed interface. These libraries generally include configuration data, documentation, message templates, pre-written code, help data, and subroutines, classes, values, and so on.

One of the main reasons behind using these Android libraries is to encourage the development process. This means to develop a great application with no extra efforts. These libraries offer necessary pre-composed codes and extra significant factors to use directly rather than performing these tasks from scratch. Thus, regardless of whether you’re learning about Android applications creation or need a mobile application on Android, at that point knowledge of these famous libraries are necessary. These are the go-to tool of nearly Android application development companies.

Top 15 Android Libraries for App Development

1. Dagger 2 (Dependency Injector Library)-

Perhaps the best thing about Dagger 2 is that it relies upon practicing Java footnotes processors along with compile-time to evaluate and analyze dependencies. On the other hand, different Java dependency injection libraries experience limitations, for example, relying on XML, facing validating dependency issues at run-time or getting performance penalties during startup.

public class MainActivity extends Activity {
@Inject MyTwitterApiClient mTwitterApiClient;
@Inject SharedPreferences sharedPreferences;
public void onCreate(Bundle savedInstance) {
// assign singleton instances to fields
InjectorClass.inject(this);
}

2. Retrofit (Networking)-

It is a type safe REST client for Java and Android, successfully mapping an API into a client interface with the assistance of commentaries. Prior, if you need to make a network request, you need to implement an Async task class. After that, you can use HttpsUrlConnection to retrieve data, something that was not perfect when dealing with APIs delivering large data. Now, Retrofit has fixed it.

Start the program by adding the dependency to your applications build. Gradle file :

  • implementation ‘com.squareup.retrofit2:retrofit:2.3.0’

Thereafter, you have to include a dependency for converters that you expect to apply:

  • implementation ‘com.squareup.retrofit2:converter-gson:2.3.0’
  • implementation ‘com.squareup.retrofit2:converter-scalars:2.3.0’

3. Glide (Image loading)-

Glide is another most appreciated image loader, which is one of the new Android libraries for developers, maintained by Bumptech. Also, Google recommends it. It not only offers animated GIF support while managing caching and image loading, but also helps with decoding, fetching, displaying video calls, GIFs, and images. It includes flexible API empowering developers to plug in any network heap, according to its default HttpUrlConnection.

4. Picasso (Image loading)-

Picasso is a trusted and widely used Android image library. It is managed by Square. It gives seamless image loading in the application that you will generally find in a single line of code.

Picasso.get().load(“http://i.imgur.com/DvpvklR.png”).into(imageView);

5. CamView (Scanning)

This is another option to the ZXing barcode scanner. It is an Android camera that effectively accesses the library with an installed QR scanner, which is based on ZXing.

CamView library maintains a wide range of elements that includes layout files, enabling developers to-

  • Scanning barcodes with the help of ZXing’s built-in decoding engine
  • To perform your camera live data processing
  • You can preview live video from the camera of Android devices

6. Zxing (Scanning)-

Abbreviation for ‘Zebra Crossing’, ZXing is a barcode image processing  Android library. It is executed in Java, with respect to other programming languages. This library also assists in the 1D industrial, 1D product, and 2D barcodes.

7. Android data binding (View binding)-

The Android Databinding library requires the most insignificant of Android Studio Version 1.3 to work. This view-binding library for Android doesn’t use commentaries. It allows you to combine UI elements in the layouts to data sources in the application with the help of declarative form rather than programmatically. In this, layouts are outlined in activities with code that requires UI framework arrangements, i.e., take a gander at the code below. It describes findViewById() to find TextView widget while binding it to userName property of the mutable viewModel.

  • TextView textView = findViewById(R.id.sample_text);
  • textView.setText(viewModel.getUserName());

8. ButterKnife (View Binding)-

Developed by Jake Wharton, ButterKnife is a famous view binding library helping in assigning ids to views easily, thus avoiding the excess of findViewByld. The statement- “Butterknife is like Dagger just infinitely less sharp” means that view binding is kind of dependency injection. The main difference is that in ButterKnife annotations are used to produce boilerplate code.

The below code shows that ButterKnife eliminates the requirement for things like onClick and onTouch while replacing them with auto injected code.

class MyButterKnifeActivity extends Activity {
@BindView(R.id.name) TextView name;
@BindView(R.id.address) TextView address;
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.simple_activity);
ButterKnife.bind(this); // MUST BE CALLED BEFORE ACCESSING UI FIELDS
name.setText(“etc etc”);
}
}

9. Stetho (Debugging)-

Stetho intends to be a refined debug platform for Android applications. You can upgrade this library boundlessly; it isn’t restricted to Network inspection, JavaScript Console, Database inspection, and so on. When you choose Android application development services, they use this to access the Chrome Developer Tools features that are commonly a part of the Chrome desktop browser.

10. RxJava2 (React programming)-

If you are searching for a library that helps you in implementing reactive programming (create reactive applications), at that point RxJava is a perfect decision for you. It is described as “a library for creating asynchronous and event-based programs by using noticeable sequences”. This library is viewed as brilliant by Android application developers since it simplifies the process to chain async tasks, opens an increasingly explicit approach to declare how concurrent operations should work, is able to highlight errors sooner than different libraries, among other things.

11. Holo graph library (Drawing)-

This is a new graphics library that is continually developing and turning into the most loved of numerous Android application development companies. For including elegantly designed charts and graphs into Android applications, this library is amazing.

<com.echo.holographlibrary.LineGraph
android:layout_width=”match_parent”
android:layout_height=”200dp”
android:id=”@+id/graph”/>

12. Gravity view (UI Components)-

It is a well-known concept in the market. For image tilting with sensors, this library can be used. Gravity View aims to optimize the motion sensors of Android devices, allowing users to achieve certain functions by rotating their device. Find is the first application where this library was used and since then it has continued to be everyone’s favorite. For using this application one needs to use Android 3.0 and higher versions.

13. Espresso (Testing)-

Espresso is an important part of the Android testing support library, which is an obvious test framework that allows developers to build UI tests for Android purposes.

Assuming that this library allows you to write tests, it checks whether the text of a TextView is related with another text or not. It gives the impression of a real user using the application. Thus, to use this library, you have to add dependencies to the application module build.gradle file.

  • androidTestCompile ‘com.android.support.test.espresso:espresso-core:3.0.1’
  • androidTestCompile ‘com.android.support.test:runner:1.0.1’

14. Robolectric (Testing)-

Robolectric is the second most unparalleled unit testing library after Espresso. This library controls inflation of resource loading, views, including numerous different perspectives. It can perform tests created in the library more efficiently and impressively. To just put over, Robolectric imitates the Android SDK for the tests, reducing the need for extra mocking frameworks like Mockito.

15. MPAndroidChart (Drawing)-

MPAndroidChart is an excellent Android chart/graph view library. It supports line, bar, radar, bubble, candlestick charts, pie alongside scaling, dragging, and animations.
