How to Integrate In-App Review API into Android App?

The developers can seamlessly gather user feedback and ratings within their Android app by integrating the In-App Review API. This integration eliminates the need for users to be redirected to external review platforms, simplifying the process. With this API, developers can conveniently trigger an in-app review flow, allowing users to easily provide their valuable feedback.

The In-App Review API integration empowers developers to enhance user engagement and satisfaction. By capturing valuable insights directly within the app experience, developers can efficiently gather user reviews, improve app ratings, and iterate on their application based on user feedback. This leads to a more robust and user-centric app.

In-App Review API

The In-App Review API is a tool provided by Google Play services for Android developers. It enables them to seamlessly ask users within their own apps to provide reviews and ratings. This helps improve the visibility and credibility of their applications in the Google Play Store.

Developers can easily integrate an in-app review flow by utilizing this API. This eliminates the hassle of users having to navigate to external review platforms. As a result, gathering user feedback becomes simplified and developers are empowered to enhance user engage-ment and collect valuable insights directly within the app. By improving app ratings and boosting user satisfaction, this API proves instrumental in optimizing the overall performance of applications.

Approaches

To integrate the In-App Review API into your Android app, you can follow the following methods:

• Using Google Play Core Library

• Using the Play Core Kotlin Extensions (KTX)

Using Google Play Core Library

To integrate the In-App Review API into your Android app using the Google Play Core Library, you need to add the library dependency to your project. Then, in the desired activity or fragment, create a ReviewManager instance and request a review from the user by calling the requestReviewFlow() method. If successful, obtain the ReviewInfo object and launch the in-app review flow using the launchReviewFlow() method. You can listen for the completion of the review flow using the onCompleteListener. This method provides a straightforward way to integrate the API into your app.

Algorithm

• Add the Google Play Core library to your project.

• Create a ReviewManager instance.

• Request a review from the user using requestReviewFlow().

• If successful, obtain the ReviewInfo object.

• Launch the in-app review flow using launchReviewFlow().

• Listen for the completion of the flow using an onCompleteListener.

Example

import android.os.Bundle;
import android.util.Log;

import androidx.appcompat.app.AppCompatActivity;

import com.google.android.play.core.review.ReviewInfo;
import com.google.android.play.core.review.ReviewManager;
import com.google.android.play.core.review.ReviewManagerFactory;
import com.google.android.play.core.review.ReviewRequest;
import com.google.android.play.core.tasks.Task;
import com.google.android.play.core.tasks.OnCompleteListener;
import com.google.android.play.core.tasks.OnFailureListener;
import com.google.android.play.core.tasks.OnSuccessListener;

public class MainActivity extends AppCompatActivity {

   private static final String TAG = "InAppReviewExample";

   private ReviewManager reviewManager;
   private ReviewInfo reviewInfo;

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

      // Create the ReviewManager instance
      reviewManager = ReviewManagerFactory.create(this);

      // Request a ReviewInfo object
      Task<ReviewInfo> request = reviewManager.requestReviewFlow();

      request.addOnCompleteListener(new OnCompleteListener<ReviewInfo>() {
         @Override
         public void onComplete(Task<ReviewInfo> task) {
            if (task.isSuccessful()) {
               // Get the ReviewInfo object
               reviewInfo = task.getResult();

               // Display the in-app review dialog
               Task<Void> flow = reviewManager.launchReviewFlow(MainActivity.this, reviewInfo);
               flow.addOnCompleteListener(new OnCompleteListener<Void>() {
                  @Override
                  public void onComplete(Task<Void> task) {
                     // The in-app review flow has finished.
                     Log.d(TAG, "In-app review completed");
                  }
               });
            } else {
               // There was some problem getting the ReviewInfo object.
               Log.e(TAG, "Error getting ReviewInfo: " + task.getException().getMessage());
            }
         }
      });
   }
}

Using the Play Core Kotlin Extensions (KTX)

The Play Core Kotlin Extensions provide a more concise way to integrate the In-App Review API into your Android app. After adding the Play Core Kotlin Extensions library to your project, create a ReviewManager instance. Request a review from the user using requestReviewFlow(), and if successful, obtain the ReviewInfo object. Launch the in-app review flow using launchReviewFlow(), and listen for the completion of the flow using the onCompleteListener. This method leverages Kotlin's concise syntax and simplifies the integration process.

Algorithm

• Add the Play Core Kotlin Extensions library to your project.

• Create a ReviewManager instance.

• Request a review from the user using requestReviewFlow().

• If successful, obtain the ReviewInfo object.

• Launch the in-app review flow using launchReviewFlow().

• Listen for the completion of the flow using an onCompleteListener.

Example

import android.os.Bundle;
import android.widget.Toast;

import androidx.appcompat.app.AppCompatActivity;

import com.google.android.play.core.ktx.reviewManager
import com.google.android.play.core.review.ReviewInfo
import com.google.android.play.core.review.ReviewManagerFactory
import com.google.android.play.core.tasks.Task

class MainActivity : AppCompatActivity() {

   private val reviewManager by lazy { ReviewManagerFactory.create(this) }

   override fun onCreate(savedInstanceState: Bundle?) {
      super.onCreate(savedInstanceState)
      setContentView(R.layout.activity_main)

      requestReview()
   }

   private fun requestReview() {
      val request: Task<ReviewInfo> = reviewManager.requestReviewFlow()
      request.addOnCompleteListener { task ->
         if (task.isSuccessful) {
            val reviewInfo: ReviewInfo = task.result
            val flow: Task<Void> = reviewManager.launchReviewFlow(this@MainActivity, reviewInfo)
            flow.addOnCompleteListener { flowTask ->
               Toast.makeText(this@MainActivity, "In-app review completed.", Toast.LENGTH_SHORT).show()
            }
         } else {
            Toast.makeText(this@MainActivity, "Error requesting in-app review.", Toast.LENGTH_SHORT).show()
         }
      }
   }
}
