Facebook权限对话框不会提示

Question

我正在创建一个Android应用程序，要求用户提供此权限：默认登录权限+ user_friends + publish_action。

在我的第一个活动中，我做了Login +询问“user_friends”权限并且工作得很好。

现在在我的第二个活动中，我想要在AlertDialog选择后请求“publish_action”权限。 的问题是，我从未promped为“publish_action”对话框中的应用程序跳过请求，并继续调用另一个活动（排行榜）

这里是我的第二个活动：

CallbackManager callbackManager; 

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

    FacebookSdk.sdkInitialize(getApplicationContext()); 

    setContentView(R.layout.activity_main); 

callbackManager = CallbackManager.Factory.create(); 
final Context context = this; 

//stuff 

b_exit.setOnClickListener(new View.OnClickListener() 
    { 
     public void onClick(View V) 
     { 

      final AlertDialog.Builder builder = new AlertDialog.Builder(context); 
      builder.setMessage(getString(R.string.salva_dati)) 
        .setCancelable(true) 
        .setPositiveButton(getString(R.string.si), new DialogInterface.OnClickListener() { 
         public void onClick(@SuppressWarnings("unused") final DialogInterface dialog, @SuppressWarnings("unused") final int id) { 

            askForFBPublishPerm(); 

            SharedPreferences.Editor editor = sharedpreferences.edit(); 
            editor.clear(); 
            editor.apply(); 

            Intent intent = new Intent(getApplicationContext(), Leaderboard.class); 
            startActivity(intent); // IT START WITHOUT ASK ME THE PERMISSION 
           } 
          } 
         } 
        }) 
} 

void askForFBPublishPerm(){ 
    Log.d("perm", "asking for the permissions"); //I SEE THAT LOG BUT NOTHING MORE AFTER THAT LINE 
    callbackManager = CallbackManager.Factory.create(); 
    LoginManager.getInstance().logInWithPublishPermissions(this,Arrays.asList("publish_actions")); 

    LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() { 
     @Override 
     public void onSuccess(LoginResult loginResult) { 
       Log.d("perm", "SUCCESS");//I DONT SEE THAT LOG 
      } 

     @Override 
     public void onCancel() { 
      Toast.makeText(getApplicationContext(), "cancelled while asking publish permission", Toast.LENGTH_LONG).show(); 
      Log.d("perm", "cancelled while asking publish permission"); 
      //I DONT SEE THAT LOG 
     } 

     @Override 
     public void onError(FacebookException error) { 
      Toast.makeText(getApplicationContext(), "error occurred while asking publish permission!", Toast.LENGTH_LONG).show(); 
      Log.d("perm", "error occurred while asking publish permission!"); //I DONT SEE THAT LOG 

     } 
    }); 

} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
super.onActivityResult(requestCode, resultCode, data); 
callbackManager.onActivityResult(requestCode, resultCode, data); 
} 

在我的日志我看到askForFBPublishPerm（）被称为，但它永远不会进入onSuccess（）或onCancel（）或onError（）。

我也通过Facebook审查了我的应用程序，他们给了我“publish_action”权限。

此“publish_action”请求不工作，我不知道为什么，有人可以帮助我吗？谢谢你的建议

在onActivityResult中处理你的回调管理器。只需应用此代码即可。

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    callbackManager.onActivityResult(requestCode, resultCode, data); // this line is required 
}
