当应用程序处于后台/未运行时，不会打开通知时的特定活动

只有当应用程序打开并执行通知单击时，通知单击才会启动指定的活动。如果应用程序处于后台/未运行状态并执行通知单击，则应用程序的MainActivity将打开。简而言之，它就像应用程序在活动堆栈后正常打开，而不是在PendingIntent中打开指定的活动。当应用程序处于后台/未运行时，不会打开通知时的特定活动

我想根据它们的类型将通知点击重定向到两个不同的活动（ApprovalDetailActivity和ConversationDetailActivity）。

我正在使用FCM进行推送通知。我在这里粘贴我的Manifest文件和我的FCMListener文件。请帮助我。

sendNotification的（）功能MyFirebaseMessagingService.java

private void sendNotification(String messageBody) 
    { 
     Intent intent; 
     System.out.println("----message body: " + messageBody); 
     if(notificationBundle.getCategory().equalsIgnoreCase(Master.KEY_PUSH_NOTIFICATION_CONVERSATION)) 
     { 
      intent = new Intent(this, ConversationDetailActivity.class); 
      /*Conversation conversation = Master.notificationBundle.getConversation(); 
      Master.conversationsList = new ArrayList<>(); 
      Master.conversationsList.add(conversation);*/ 
     } 
     else 
     { 
      intent = new Intent(this, ApprovalDetailActivity.class); 
      if(notificationBundle.getApprovalType().equals("I")) 
       intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_VERIFICATIONS); 
      else if(notificationBundle.getApprovalType().equals("A")) 
       intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_APPROVALS); 
      else 
       intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_COMPLETED); 

      intent.putExtra(Master.KEY_IS_FROM_CONVERSATION, false); 
     } 

     intent.putExtra(Master.KEY_PUSH_NOTIFICATION_POST_ID , notificationBundle.getPostID()); 
     intent.putExtra(Master.KEY_IS_FROM_PUSH_NOTIFICATION, true); 
     intent.putExtra(Master.KEY_POSITION, 0); 

     intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
     PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 
       PendingIntent.FLAG_ONE_SHOT); 

     Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
     NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) 
       .setSmallIcon(R.drawable.mnet_icon) 
       .setContentTitle(getString(R.string.app_name)) 
       .setContentText(messageBody) 
       .setAutoCancel(true) 
       .setSound(defaultSoundUri) 
       .setContentIntent(pendingIntent); 

     NotificationManager notificationManager = 
       (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 

     int random = (int) ((new Date().getTime()/1000L) % Integer.MAX_VALUE); 
     notificationManager.notify(random, notificationBuilder.build()); 
    }

使用PendingIntent.FLAG_UPDATE_CURRENT –

标志使用'PendingIntent.FLAG_UPDATE_CURRENT'将登陆你到你的活动。保持编码伙伴;）hahaahaha – buzzingsilently

按照火力地堡云端通讯文件，如果活动是在前台，然后onMessageReceived将调用。如果活动处于后台或关闭状态，则会在通知中心显示通知消息以显示应用启动器活动。 For More information Check this link

Launcher Activity（LoginActivity）的意图有Extras。但是，当我从此Activity启动ConversationDetailActivity（如果存在FCM额外功能）时，startActivity（）函数不会执行任何操作。所以，ConversationDetailActivity不开放。可能是什么原因？ – backslashN

您是否已将此标志添加到意图中？ intent.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）; –

是的，我也尝试过，它没有帮助。我已经为此问题发布了另一个问题。请在这里回答：[链接]（http://stackoverflow.com/questions/40842313/startactivity-does-nothing-even-when-the-intent-is-specified-correctly） – backslashN

在启动器活动中从意图获取包（用于推送通知数据有效载荷），然后开始您的特定活动。

我想我得到了确切的答案给你。

TaskStackBuilder Usage and Definition

请不要忽略了真棒视频到上面的链接。

TaskStackBuilder taskStackBuilder = TaskStackBuilder.create(getContext()); 
taskStackBuilder.addNextIntentWithParentStack(intent); 
PendingIntent pendingIntent = taskStackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
