android-in-app-review

A sample demonstration of Android's new In-App Review API which lets you prompt users to submit Play Store ratings and reviews without the inconvenience of leaving your app or game.

HOW TO USE

1. Import the Play Core Library into your project: Add the following in your app’s build.gradle file:

dependencies {
    // This dependency is downloaded from the Google’s Maven repository.
    // So, make sure you also include that repository in your project's build.gradle file.
    implementation 'com.google.android.play:core:1.8.2'

    // For Kotlin users also import the Kotlin extensions library for Play Core:
    implementation 'com.google.android.play:core-ktx:1.8.1'
}

2. Create the ReviewManager instance

// If using kotlin: 
val manager = ReviewManagerFactory.create(context)

// If using Java:
ReviewManager manager = ReviewManagerFactory.create(context)

3. Request a ReviewInfo object

// If using kotlin: 
val request = manager.requestReviewFlow()
request.addOnCompleteListener { request ->
    if (request.isSuccessful) {
        // We got the ReviewInfo object
        val reviewInfo = request.result
        val flow = manager.launchReviewFlow(activity, reviewInfo)
        flow.addOnCompleteListener { _ ->
            // 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.
        }
    } else {
        // There was some problem, continue regardless of the result.
        // you can show your own rate dialog alert and redirect user to your app page
        // on play store.
    }
}

// If using Java
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();
        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.
        });
    } else {
        // There was some problem, continue regardless of the result.
        // you can show your own rate dialog alert and redirect user to your app page
        // on play store.
    }
});
