应用程序内评论API是谷歌在2020年8月推出的一个期待已久的功能，就像苹果在2016年为iOS应用程序推出的功能一样。

有了这个API，用户不用离开就可以对应用程序进行审查和评分。谷歌建议开发人员不要强迫用户一直进行评分或审查，因为这个API在一段时间内为每个用户分配了应用程序的特定使用配额。开发人员当然不能在他们的任务中间用一个诱人的弹出窗口打断用户。

Java

In Application level (build.gradle)

       dependencies {
            // This dependency from the Google Maven repository.
            // include that repository in your project's build.gradle file.
            implementation 'com.google.android.play:core:1.9.0'
        }

 

boolean isGMSAvailable = false;
int result = GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(this);
isGMSAvailable = (com.google.android.gms.common.ConnectionResult.SUCCESS == result);
  if(isGMSAvailable)
  {
    ReviewManager manager = ReviewManagerFactory.create(this);
    Task<ReviewInfo> request = manager.requestReviewFlow();
    request.addOnCompleteListener(task -> {
      try {
        if (task.isSuccessful())
        {
           // getting 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 old method for rating and user will land in Play Store App page
           Utils.rateOnPlayStore(this);       
        }
        } catch (Exception ex)
        {
            Log.e("review Ex", "review & rate: "+ ex);
                 }
                });
    }
    else
    {
       // if user has not installed Google play services in his/her device you land them to 
       // specific store e.g. Huawei AppGallery or Samsung Galaxy Store 
       Utils.rateOnOtherStore(this);
    }   

科特林

val manager = ReviewManagerFactory.create(context)
val request = manager.requestReviewFlow()
request.addOnCompleteListener { request ->
    if (request.isSuccessful) {
        // We got the ReviewInfo object
        val reviewInfo = request.result
    } else {
        // There was some problem, continue regardless of the result.
    }
}

//Launch the in-app review flow

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.
}

对于测试使用FakeReviewManager

//java
ReviewManager manager = new FakeReviewManager(this);

//Kotlin
val manager = FakeReviewManager(context)

另一个可能对你有用的方法是Linkify。如果我有一个TextView，是要求用户评价应用程序，我可以链接两个词在文本中，使他们突出显示，当用户触摸他们，播放商店打开，准备他们的审查:

class playTransformFilter implements TransformFilter {
   public String transformUrl(Matcher match, String url) {
        return "market://details?id=com.qwertyasd.yourapp";
   }
}

class playMatchFilter implements MatchFilter {
    public boolean acceptMatch(CharSequence s, int start, int end) {
        return true;
    }
}
text1 = (TextView) findViewById(R.id.text1);
text1.setText("Please rate it.");
final Pattern playMatcher = Pattern.compile("rate it");
Linkify.addLinks(text1, playMatcher, "", 
                   new playMatchFilter(), new playTransformFilter());

Play Store评分

 btn_rate_us.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Uri uri = Uri.parse("market://details?id=" + getPackageName());
                Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
                // To count with Play market backstack, After pressing back button,
                // to taken back to our application, we need to add following flags to intent.
                goToMarket.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY |
                        Intent.FLAG_ACTIVITY_NEW_DOCUMENT |
                        Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
                try {
                    startActivity(goToMarket);
                } catch (ActivityNotFoundException e) {
                    startActivity(new Intent(Intent.ACTION_VIEW,
                            Uri.parse("http://play.google.com/store/apps/details?id=" + getPackageName())));
                }
            }
        });

你可以使用这个简单的代码来评估你的应用程序在你的活动。

try {
    Uri uri = Uri.parse("market://details?id=" + getPackageName());
    Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
    startActivity(goToMarket);
} catch (ActivityNotFoundException e) {
    startActivity(new Intent(Intent.ACTION_VIEW,
    Uri.parse("http://play.google.com/store/apps/details?id=" + getPackageName())));
}

前提是你同时在谷歌Play Store和Amazon Appstore发布应用。我还处理过用户(尤其是中国用户)既没有应用商店又没有浏览器的情况。

public void goToMyApp(boolean googlePlay) {//true if Google Play, false if Amazone Store
    try {
       startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse((googlePlay ? "market://details?id=" : "amzn://apps/android?p=") +getPackageName())));
    } catch (ActivityNotFoundException e1) {
        try {
            startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse((googlePlay ? "http://play.google.com/store/apps/details?id=" : "http://www.amazon.com/gp/mas/dl/android?p=") +getPackageName())));
        } catch (ActivityNotFoundException e2) {
            Toast.makeText(this, "You don't have any app that can open this link", Toast.LENGTH_SHORT).show();
        }
    }
}

一个kotlin版本

fun openAppInPlayStore() {
    val uri = Uri.parse("market://details?id=" + context.packageName)
    val goToMarketIntent = Intent(Intent.ACTION_VIEW, uri)

    var flags = Intent.FLAG_ACTIVITY_NO_HISTORY or Intent.FLAG_ACTIVITY_MULTIPLE_TASK
    flags = if (Build.VERSION.SDK_INT >= 21) {
        flags or Intent.FLAG_ACTIVITY_NEW_DOCUMENT
    } else {
        flags or Intent.FLAG_ACTIVITY_CLEAR_TASK
    }
    goToMarketIntent.addFlags(flags)

    try {
        startActivity(context, goToMarketIntent, null)
    } catch (e: ActivityNotFoundException) {
        val intent = Intent(Intent.ACTION_VIEW,
                Uri.parse("http://play.google.com/store/apps/details?id=" + context.packageName))

        startActivity(context, intent, null)
    }
}
