Android Studio Google Play In App Review

The Google Play In-App Review API lets you prompt users to submit Play Store ratings and reviews without the inconvenience of leaving your app or game.Example is as shown below:

In this tutorial I will show you how to add it in your application.

1.Add the required dependancy in your build.gradle

implementation 'com.google.android.play:core:1.8.2'

2.Create an instance of ReviewManager which will help in starting the flow.

ReviewManager manager = ReviewManagerFactory.create(this);

3.Request a reviewInfo object

ReviewManager manager = ReviewManagerFactory.create(this);
Task<ReviewInfo> request = manager.requestReviewFlow();
request.addOnCompleteListener(task -> {
    if (task.isSuccessful()) {
        // We can get the ReviewInfo object
        ReviewInfo reviewInfo = task.getResult();
    } else {
        // There was some problem, continue regardless of the result.
    }
});

4.Launch the in app review dialog

Task<Void> flow = manager.launchReviewFlow(activity, reviewInfo);
flow.addOnCompleteListener(task -> {
    // The flow has finished. The API does not indicate whether the user
    // reviewed or not, or even whether the review dialog was shown. Thus, no
    // matter the result, we continue our app flow.
});

Your whole code should appear like below:

ReviewManager manager;
private ReviewInfo reviewInfo;
manager = ReviewManagerFactory.create(this);

Task<ReviewInfo> request = manager.requestReviewFlow();
request.addOnCompleteListener(task -> {
    if (task.isSuccessful()) {
        reviewInfo = task.getResult();
        Task<Void> flow = manager.launchReviewFlow(YOURACTIVITY.this, reviewInfo);
        flow.addOnCompleteListener(taskdone -> {
           // This is the next follow of your app 
       });
    }
});
// other action, please DO NOT add any flow after Task because i will run parawell, you must to add in addOnCompleteListener
