Google Play 应用内评价

1.添加Play Core SDK

在.grade文件dependencies中添加如下代码：

dependencies {
        //gp应用内评价
    implementation 'com.google.android.play:core:1.10.0'
}

2. 请求 ReviewInfo 对象

在第一个Activity脚本中初始化应用内评价

请遵循有关何时请求应用内评价的指南，以确定在应用的用户流的哪些阶段适合提示用户进行评价（例如，当用户在游戏中完成某个关卡时）。当您的应用达到其中一个阶段时，请使用

[ReviewManager](https://developer.android.google.cn/reference/com/google/android/play/core/review/ReviewManager) 实例创建请求任务。如果请求成功，该 API 将返回启动应用内评价流程所需的 [ReviewInfo](https://developer.android.google.cn/reference/com/google/android/play/core/review/ReviewInfo) 对象。

private ReviewManager manager;
private ReviewInfo reviewInfo;
@Override protected void onCreate(Bundle savedInstanceState)
    {
        manager =  ReviewManagerFactory.create(mContext);
        //manager = new FakeReviewManager(mContext); //模拟调用api是否正常，需要用上面代码发布测试渠道测试
        Task<ReviewInfo> request = manager.requestReviewFlow();
        request.addOnCompleteListener(task -> {
            if (task.isSuccessful()) {
                // We can get the ReviewInfo object
                reviewInfo = task.getResult();
                Log.i(TAG, "initHwSDK gp: "+ Thread.currentThread().getId());

            } else {
                // There was some problem, log or handle the error code.
                //@ReviewErrorCode int reviewErrorCode = ((TaskException) task.getException()).getErrorCode();
                Log.i(TAG, "initHwSDK gp error: ");
            }
        });
    }

3.启动应用内评价流程

在游戏逻辑中调用以下java代码接口,使用 [ReviewInfo](https://developer.android.google.cn/reference/com/google/android/play/core/review/ReviewInfo) 实例启动应用内评价流程。等到用户完成应用内评价流程后，再继续执行应用的正常用户流（例如进入下一关）。

public  void  showComment(){
        Log.i(TAG, "showComment: ");
        if(manager != null && reviewInfo != null){
            Task<Void> flow = manager.launchReviewFlow(mContext, 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.
                Log.i(TAG, "showComment: success");
            });
        }
    }
