How to implement Rate It feature in Android App

Question

I am developing an Android App. In which everything is working right. My app is ready to launch. But there I need to implement one more feature. I need to display a popup that contains

Rate It and Remind me later

Here if any user rates the app in the market then the popup won't be disappeared. I have searched in Google and found one link. With this, I understand that it's not possible to know. So I need a suggestion for this.

Has anybody faced this situation before? If so, is there any solution or any alternative for this?

Answer 1

I implemented this a while back, to some extent. It is impossible to know whether or not a user has rated an app, to prevent ratings from becoming a currency (some developers might add an option like "Rate this app and get so and so in the app for free").

The class I wrote provides three buttons, and configures the dialog so that it is only shown after the app has been launched n times (users have a higher chance of rating the app if they've used it a bit before. Most of them are unlikely to even know what it does on the first run):

public class AppRater {
    private final static String APP_TITLE = "App Name";// App Name
    private final static String APP_PNAME = "com.example.name";// Package Name

    private final static int DAYS_UNTIL_PROMPT = 3;//Min number of days
    private final static int LAUNCHES_UNTIL_PROMPT = 3;//Min number of launches

    public static void app_launched(Context mContext) {
        SharedPreferences prefs = mContext.getSharedPreferences("apprater", 0);
        if (prefs.getBoolean("dontshowagain", false)) { return ; }

        SharedPreferences.Editor editor = prefs.edit();

        // Increment launch counter
        long launch_count = prefs.getLong("launch_count", 0) + 1;
        editor.putLong("launch_count", launch_count);

        // Get date of first launch
        Long date_firstLaunch = prefs.getLong("date_firstlaunch", 0);
        if (date_firstLaunch == 0) {
            date_firstLaunch = System.currentTimeMillis();
            editor.putLong("date_firstlaunch", date_firstLaunch);
        }

        // Wait at least n days before opening
        if (launch_count >= LAUNCHES_UNTIL_PROMPT) {
            if (System.currentTimeMillis() >= date_firstLaunch + 
                    (DAYS_UNTIL_PROMPT * 24 * 60 * 60 * 1000)) {
                showRateDialog(mContext, editor);
            }
        }

        editor.commit();
    }   

    public static void showRateDialog(final Context mContext, final SharedPreferences.Editor editor) {
        final Dialog dialog = new Dialog(mContext);
        dialog.setTitle("Rate " + APP_TITLE);

        LinearLayout ll = new LinearLayout(mContext);
        ll.setOrientation(LinearLayout.VERTICAL);

        TextView tv = new TextView(mContext);
        tv.setText("If you enjoy using " + APP_TITLE + ", please take a moment to rate it. Thanks for your support!");
        tv.setWidth(240);
        tv.setPadding(4, 0, 4, 10);
        ll.addView(tv);

        Button b1 = new Button(mContext);
        b1.setText("Rate " + APP_TITLE);
        b1.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                mContext.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + APP_PNAME)));
                dialog.dismiss();
            }
        });        
        ll.addView(b1);

        Button b2 = new Button(mContext);
        b2.setText("Remind me later");
        b2.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                dialog.dismiss();
            }
        });
        ll.addView(b2);

        Button b3 = new Button(mContext);
        b3.setText("No, thanks");
        b3.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                if (editor != null) {
                    editor.putBoolean("dontshowagain", true);
                    editor.commit();
                }
                dialog.dismiss();
            }
        });
        ll.addView(b3);

        dialog.setContentView(ll);        
        dialog.show();        
    }
}

Integrating the class is as simple as adding:

AppRater.app_launched(this);

To your Activity. It only needs to be added to one Activity in the entire app.

Answer 2

My one using DialogFragment:

public class RateItDialogFragment extends DialogFragment {
    private static final int LAUNCHES_UNTIL_PROMPT = 10;
    private static final int DAYS_UNTIL_PROMPT = 3;
    private static final int MILLIS_UNTIL_PROMPT = DAYS_UNTIL_PROMPT * 24 * 60 * 60 * 1000;
    private static final String PREF_NAME = "APP_RATER";
    private static final String LAST_PROMPT = "LAST_PROMPT";
    private static final String LAUNCHES = "LAUNCHES";
    private static final String DISABLED = "DISABLED";

    public static void show(Context context, FragmentManager fragmentManager) {
        boolean shouldShow = false;
        SharedPreferences sharedPreferences = getSharedPreferences(context);
        SharedPreferences.Editor editor = sharedPreferences.edit();
        long currentTime = System.currentTimeMillis();
        long lastPromptTime = sharedPreferences.getLong(LAST_PROMPT, 0);
        if (lastPromptTime == 0) {
            lastPromptTime = currentTime;
            editor.putLong(LAST_PROMPT, lastPromptTime);
        }

        if (!sharedPreferences.getBoolean(DISABLED, false)) {
            int launches = sharedPreferences.getInt(LAUNCHES, 0) + 1;
            if (launches > LAUNCHES_UNTIL_PROMPT) {
                if (currentTime > lastPromptTime + MILLIS_UNTIL_PROMPT) {
                    shouldShow = true;
                }
            }
            editor.putInt(LAUNCHES, launches);
        }

        if (shouldShow) {
            editor.putInt(LAUNCHES, 0).putLong(LAST_PROMPT, System.currentTimeMillis()).commit();
            new RateItDialogFragment().show(fragmentManager, null);
        } else {
            editor.commit();
        }
    }

    private static SharedPreferences getSharedPreferences(Context context) {
        return context.getSharedPreferences(PREF_NAME, 0);
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        return new AlertDialog.Builder(getActivity())
                .setTitle(R.string.rate_title)
                .setMessage(R.string.rate_message)
                .setPositiveButton(R.string.rate_positive, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + getActivity().getPackageName())));
                        getSharedPreferences(getActivity()).edit().putBoolean(DISABLED, true).commit();
                        dismiss();
                    }
                })
                .setNeutralButton(R.string.rate_remind_later, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dismiss();
                    }
                })
                .setNegativeButton(R.string.rate_never, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        getSharedPreferences(getActivity()).edit().putBoolean(DISABLED, true).commit();
                        dismiss();
                    }
                }).create();
    }
}

Then use it in onCreate() of your main FragmentActivity:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...

    RateItDialogFragment.show(this, getFragmentManager());

}

Answer 3

Java & Kotlin solution (In-app review API by Google in 2020):

First, in your build.gradle(app) file, add following dependencies (full setup here)

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:1.8.0'
}

Add this method to your Activity:

void askRatings() {
    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(this, reviewInfo);
            flow.addOnCompleteListener(task2 -> {
                // 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.
        }
    });
}

Call it like any other method:

askRatings();

Answer 4

I think what you are trying to do is probably counter-productive.

Making it easy for people to rate apps is generally a good idea, as most people who bother do so because they like the app. It is rumoured that the number of ratings affects your market rating (although I see little evidence of this). Hassling users into rating - through nag screens - is likely to cause people to clear the nag through leaving a bad rating.

Adding the capability to directly rate an app has caused a slight decrease in the numerical ratings for my free version, and a slight increase in my paid app. For the free app, my 4 star ratings increased more than my 5 star ratings, as people who thought my app was good but not great started to rate it as well. Change was about -0.2. For the paid, change was about +0.1. I should remove it from the free version, except I like getting lots of comments.

I put my rating button into a settings (preference) screen, where it does not affect normal operation. It still increased my rating rate by a factor of 4 or 5. I have no doubt that if I tried nagging my users into making a rating, I would get lots of users giving me bad ratings as a protest.

Answer 5

AndroidRate is a library to help you promote your android app by prompting users to rate the app after using it for a few days.

Module Gradle:

dependencies {
  implementation 'com.vorlonsoft:androidrate:1.0.8'
}

MainActivity.java:

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

  AppRate.with(this)
      .setStoreType(StoreType.GOOGLEPLAY) //default is GOOGLEPLAY (Google Play), other options are
                                          //           AMAZON (Amazon Appstore) and
                                          //           SAMSUNG (Samsung Galaxy Apps)
      .setInstallDays((byte) 0) // default 10, 0 means install day
      .setLaunchTimes((byte) 3) // default 10
      .setRemindInterval((byte) 2) // default 1
      .setRemindLaunchTimes((byte) 2) // default 1 (each launch)
      .setShowLaterButton(true) // default true
      .setDebug(false) // default false
      //Java 8+: .setOnClickButtonListener(which -> Log.d(MainActivity.class.getName(), Byte.toString(which)))
      .setOnClickButtonListener(new OnClickButtonListener() { // callback listener.
          @Override
          public void onClickButton(byte which) {
              Log.d(MainActivity.class.getName(), Byte.toString(which));
          }
      })
      .monitor();

  if (AppRate.with(this).getStoreType() == StoreType.GOOGLEPLAY) {
      //Check that Google Play is available
      if (GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(this) != ConnectionResult.SERVICE_MISSING) {
          // Show a dialog if meets conditions
          AppRate.showRateDialogIfMeetsConditions(this);
      }
  } else {
      // Show a dialog if meets conditions
      AppRate.showRateDialogIfMeetsConditions(this);
  }
}

The default conditions to show rate dialog is as below:

1. App is launched more than 10 days later than installation. Change via AppRate#setInstallDays(byte).
2. App is launched more than 10 times. Change via AppRate#setLaunchTimes(byte).
3. App is launched more than 1 days after neutral button clicked. Change via AppRate#setRemindInterval(byte).
4. App is launched X times and X % 1 = 0. Change via AppRate#setRemindLaunchTimes(byte).
5. App shows neutral dialog (Remind me later) by default. Change via setShowLaterButton(boolean).
6. To specify the callback when the button is pressed. The same value as the second argument of DialogInterface.OnClickListener#onClick will be passed in the argument of onClickButton.
7. Setting AppRate#setDebug(boolean) will ensure that the rating request is shown each time the app is launched. This feature is only for development!.

Optional custom event requirements for showing dialog

You can add additional optional requirements for showing dialog. Each requirement can be added/referenced as a unique string. You can set a minimum count for each such event (for e.g. "action_performed" 3 times, "button_clicked" 5 times, etc.)

AppRate.with(this).setMinimumEventCount(String, short);
AppRate.with(this).incrementEventCount(String);
AppRate.with(this).setEventCountValue(String, short);

Clear show dialog flag

When you want to show the dialog again, call AppRate#clearAgreeShowDialog().

AppRate.with(this).clearAgreeShowDialog();

When the button presses on

call AppRate#showRateDialog(Activity).

AppRate.with(this).showRateDialog(this);

Set custom view

call AppRate#setView(View).

LayoutInflater inflater = (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.custom_dialog, (ViewGroup)findViewById(R.id.layout_root));
AppRate.with(this).setView(view).monitor();

Specific theme

You can use a specific theme to inflate the dialog.

AppRate.with(this).setThemeResId(int);

Custom dialog

If you want to use your own dialog labels, override string xml resources on your application.

<resources>
    <string name="rate_dialog_title">Rate this app</string>
    <string name="rate_dialog_message">If you enjoy playing this app, would you mind taking a moment to rate it? It won\'t take more than a minute. Thanks for your support!</string>
    <string name="rate_dialog_ok">Rate It Now</string>
    <string name="rate_dialog_cancel">Remind Me Later</string>
    <string name="rate_dialog_no">No, Thanks</string>
</resources>

Check that Google Play is available

if (GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(this) != ConnectionResult.SERVICE_MISSING) {

}

Answer 6

Make sure the below is implemented For in-app reviews:

implementation 'com.google.android.play:core:1.8.0'

OnCreate

public void RateApp(Context mContext) {
    try {
        ReviewManager manager = ReviewManagerFactory.create(mContext);
        manager.requestReviewFlow().addOnCompleteListener(new OnCompleteListener<ReviewInfo>() {
            @Override
            public void onComplete(@NonNull Task<ReviewInfo> task) {
                if(task.isSuccessful()){
                    ReviewInfo reviewInfo = task.getResult();
                    manager.launchReviewFlow((Activity) mContext, reviewInfo).addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(Exception e) {
                            Toast.makeText(mContext, "Rating Failed", Toast.LENGTH_SHORT).show();
                        }
                    }).addOnCompleteListener(new OnCompleteListener<Void>() {
                        @Override
                        public void onComplete(@NonNull Task<Void> task) {
                            Toast.makeText(mContext, "Review Completed, Thank You!", Toast.LENGTH_SHORT).show();
                        }
                    });
                }

            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(Exception e) {
                Toast.makeText(mContext, "In-App Request Failed", Toast.LENGTH_SHORT).show();
            }
        });
    } catch (ActivityNotFoundException e) {
        e.printStackTrace();
    }
}

Answer 7

This solution is very similar to those presented above. The only difference is that you are going to be able to delay the prompt of the rating dialog per launches and days. If the remind me later button is pressed, then I will delay the pop up for 3 days and 10 launches. The same is done for those that selected to rate it, however the delays is longer (not to bother the user so soon in case that he has actually rated the app. This can be changed to not be shown again, then you will have to alter the code to your like). Hope it helps somebody!

Answer 8

Use this library, It is simple and easy.. https://github.com/hotchemi/Android-Rate

by adding the dependency..

dependencies {
  compile 'com.github.hotchemi:android-rate:0.5.6'
}

Answer 9

As of August 2020, Google Play's In-App Review API is available and its straightforward implementation is correct as per this answer.

But if you wish add some display logic on top of it, use the Five-Star-Me library.

Set launch times and install days in the onCreate method of the MainActivity to configure the library.

  FiveStarMe.with(this)
      .setInstallDays(0) // default 10, 0 means install day.
      .setLaunchTimes(3) // default 10
      .setDebug(false) // default false
      .monitor();

Then place the below method call on any activity / fragment's onCreate / onViewCreated method to show the prompt whenever the conditions are met.

FiveStarMe.showRateDialogIfMeetsConditions(this); //Where *this* is the current activity.

Installation instructions:

You can download from jitpack.

Step 1: Add this to project (root) build.gradle.

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}

Step 2: Add the following dependency to your module (app) level build.gradle.

dependencies {
  implementation 'com.github.numerative:Five-Star-Me:2.0.0'
}

Answer 11

Now you can use In App Rating feature by Google.

Here is Kotlin/Java integration official guide

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.

Generally, the in-app review flow (see figure 1) can be triggered at any time throughout the user journey of your app. During the flow, the user has the ability to rate your app using the 1 to 5 star system and to add an optional comment. Once submitted, the review is sent to the Play Store and eventually displayed.

Answer 12

As you see from the other post you have linked, there isn't a way for the app to know if the user has left a review or not. And for good reason.

Think about it, if an app could tell if the user has left a review or not, the developer could restrict certain features that would only be unlocked if the user leaves a 5/5 rating. This would lead the other users of Google Play to not trust the reviews and would undermine the rating system.

The alternative solutions I have seen is that the app reminds the user to submit a rating whenever the app is opened a specific number of times, or a set interval. For example, on every 10th time the app is opened, ask the user to leave a rating and provide a "already done" and "remind me later" button. Keep showing this message if the user has chosen to remind him/her later. Some other apps developers show this message with an increasing interval (like, 5, 10, 15nth time the app is opened), because if a user hasn't left a review on the, for example, 100th time the app was opened, it's probably likely s/he won't be leaving one.

This solution isn't perfect, but I think it's the best you have for now. It does lead you to trust the user, but realize that the alternative would mean a potentially worse experience for everyone in the app market.

Answer 14

Android’s new In-App Review system launched which lets developers ask for Play store reviews without leaving the app.

To check design guidelines and when to display a review card, refer to the official document

https://developer.android.com/guide/playcore/in-app-review

To implement:

• Add play-core library as a dependency in your build.gradle file.

implementation 'com.google.android.play:core:1.8.0'

• Create a ReviewManager instance and request ReviewInfo object. The ReviewInfo object to be pre-cached and then can trigger "launchReviewFlow" to present the Review card to the user.

   private var reviewInfo: ReviewInfo? = null
  
   val manager = ReviewManagerFactory.create(context)
  
   val request = manager.requestReviewFlow()
  
   requestFlow.addOnCompleteListener { request ->
       if (request.isSuccessful) {
           //Received ReviewInfo object
           reviewInfo = request.result
       } else {
           //Problem in receiving object
           reviewInfo = null
       }
  
   reviewInfo?.let {
       val flow = reviewManager.launchReviewFlow(this@MainActivity, it)
       flow.addOnCompleteListener {
           //Irrespective of the result, the app flow should continue
       }
   }
  

Note : It is suggested to show the review flow after the user has experienced enough of your app or game.

When to request an in-app review:

• Trigger the in-app review flow after a user has experienced enough of your app or game to provide useful feedback.
• Do not prompt the user excessively for a review. This approach helps minimize user frustration and limit API usage (see the section on quotas).
• Your app should not ask the user any questions before or while presenting the rating button or card, including questions about their opinion (such as “Do you like the app?”) or predictive questions (such as “Would you rate this app 5 stars”).

Few points before testing this:

• While testing new functionalities, mostly we create a new project that would have new ApplicationId, make sure you give an ApplicationId that is already released and available in the play store.

• If you have given feedback in the past for your app, in-app review API’s launchReviewFlow will not present any Review card. It simply triggers a success event.

• Due to quota limitations, calling a launchReviewFlow method might not always display a dialog. It should not be linked with any click event.

Answer 15

My simple approach using an In-app review system and counters.

import android.content.Context
import androidx.core.content.edit
import java.util.concurrent.TimeUnit

object Rater {
    private const val DAYS_UNTIL_PROMPT = 3L//Min number of days
    private const val LAUNCHES_UNTIL_PROMPT = 3//Min number of launches
    private const val RATER_KEY = "rater_key"
    private const val LAUNCH_COUNTER_KEY = "launch_counter_key"
    private const val FIRST_LAUNCH_KEY = "first_launch_key"

    fun Context.appRateCheck(dialog: () -> Unit) {
        val prefs = getSharedPreferences(RATER_KEY, 0)
        val launchesCounter = prefs.getLong(LAUNCH_COUNTER_KEY, 0) + 1
        prefs.edit { putLong(LAUNCH_COUNTER_KEY, launchesCounter) }

        var firstLaunch = prefs.getLong(FIRST_LAUNCH_KEY, 0)
        if (firstLaunch == 0L) {
            firstLaunch = System.currentTimeMillis()
            prefs.edit { putLong(FIRST_LAUNCH_KEY, firstLaunch) }
        }

        if (launchesCounter >= LAUNCHES_UNTIL_PROMPT) {
            if (System.currentTimeMillis() >= firstLaunch + TimeUnit.DAYS.toMillis(DAYS_UNTIL_PROMPT)) {
                dialog()
            }
        }
    }
}

Usage:

private val manager: ReviewManager by lazy { ReviewManagerFactory.create(context) }

private fun initInAppReview() {
    context?.appRateCheck {
        manager.requestReviewFlow().addOnSuccessListener {
            manager.launchReviewFlow(requireActivity(), it)
        }
    }
}

Answer 16

All those libraries are not the solution for the problem in this post. This libraries just open a webpage to the app on google play. Instead this Play core library has more consistent interface.

So I think this is the problem, ProGuard: it obfscates some classes enough https://stackoverflow.com/a/63650212/10117882

Answer 17

You can call Google In-App Review API. You do not need to count, because of Google handle this issue for you. If someone gave stars or comment previously, Google will not show again this prompt.

Look at the below code snippet.

1-) Firstly add import ReviewManagerFactory

import com.google.android.play.core.review.ReviewManagerFactory

2-) added below code snippet where appropriate place and time.

Use the ReviewInfo instance to launch the in-app review flow. Wait until the user has completed the in-app review flow before your app continues its normal user flow

fun inAppReview() {
    val reviewManager = ReviewManagerFactory.create(this)
    val requestReviewFlow = reviewManager.requestReviewFlow()
    requestReviewFlow.addOnCompleteListener { request ->
        if (request.isSuccessful) {
            // We got the ReviewInfo object
            val reviewInfo = request.result
            val flow = reviewManager.launchReviewFlow(this, reviewInfo)
            flow.addOnCompleteListener {
                // Call back
            }
        } else {
            Log.d("Error: ", request.exception.toString())
            // There was some problem, continue regardless of the result.
        }
    }
}
