Step: 1
======

Add gradle file to your dependencies in your build.gradle file under app folder

compile 'com.airbnb.android:lottie:2.2.5'


like below


dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.airbnb.android:lottie:2.2.5'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:26.1.0'
}


Step: 2
======

create an assets folder













Right click on main folder --> New  --> Folder --> Select assets folder --> Finish.

You need add after effects animation file in this assets folder.


Step: 3
======
create an activity and xml layout


package com.pratap.lottieexample;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // you can load it programmatically
       /*
        LottieAnimationView animationView = (LottieAnimationView) findViewById(R.id.animation_view_1);
        animationView.setAnimation("favourite_app_icon.json");
        animationView.loop(true);
        animationView.playAnimation();*/


        // if  you want cancel, you can use this
        // animationView.cancelAnimation();
    }
}
