In App Review

In App review Implementation using google play core library

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.

Steps:

1- Import the Play Core Library into your Android project as a Gradle dependency

implementation 'com.google.android.play:core:1.10.0'

2- Create instance of ReviewManager

ReviewManager manager = ReviewManagerFactory.create(this);

3- Request a ReviewInfo object, use the ReviewManager instance to create a request task. If successful, the API returns the ReviewInfo object needed to start the in-app review flow.

Task<ReviewInfo> request = manager.requestReviewFlow();
request.addOnCompleteListener(new OnCompleteListener<ReviewInfo>() {
    @Override
    public void onComplete(@NonNull Task<ReviewInfo> task) {
        if (task.isSuccessful()) {
            // We can get the ReviewInfo object
            reviewInfo = task.getResult();
            lunchappreview(reviewInfo);
        } else {
            // There was some problem, log or handle the error code.
            Toast.makeText(MainActivity.this, "Something went wrong", Toast.LENGTH_SHORT).show();
        }
    }
});

4- Launch the in-app review flow , Use the ReviewInfo instance to launch the in-app review flow.

private void lunchappreview(ReviewInfo reviewInfo) {
    // in app review last step
    if(reviewInfo != null){
        Task<Void> flow = manager.launchReviewFlow(this, reviewInfo);
        flow.addOnCompleteListener(new OnCompleteListener<Void>() {
            @Override
            public void onComplete(@NonNull Task<Void> task) {
                Toast.makeText(MainActivity.this, "Thanks for review the app", Toast.LENGTH_SHORT).show();
            }
        });
    }
