Android通知意圖未啟動所述活動和通知聲音問題

Question

嗨，我正在使用Firebase Cloud Messaging的應用程序上工作，並且我嘗試在應用程序使用Firebase Cloud Messaging接收消息時顯示通知。
當應用程序運行時

1. 我可以聽到通知聲
2. 當我點擊通知時，在我的情況下，它使我進入正確的活動NotificationActivity.java

現在，當關閉App時，它不會在后台運行（這些主要問題需要解決，並且需要針對這種不自然的行為進行解釋）

1. 我可以看到通知，但聽不到通知聲音。
2. 當我點擊通知時，它不會打開NotificationActivity.java而是打開Splash.java ，這是默認/啟動器活動

以下是代碼片段。

Answer 1

Use this code:    
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
           NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
           if (bitmaplogo != null) {
               notificationBuilder.setLargeIcon(bitmaplogo);
           } else {
               notificationBuilder.setLargeIcon(largeIcon);
           }
           if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
               notificationBuilder.setSmallIcon(R.drawable.app_icon_transparent);
           } else {
               notificationBuilder.setSmallIcon(R.mipmap.app_icon);
           }
           notificationBuilder.setColor(getResources().getColor(R.color.colorAccent));
           notificationBuilder.setContentTitle(getResources().getString(R.string.app_name));
           notificationBuilder.setContentText(messageBody);
           notificationBuilder.setStyle(new NotificationCompat.BigTextStyle().bigText(messageBody));
           notificationBuilder.setAutoCancel(true);
           notificationBuilder.setSound(defaultSoundUri);
           notificationBuilder.setContentIntent(pendingIntent);

           int num = (int) System.currentTimeMillis();
           NotificationManager notificationManager =
                   (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
           notificationManager.notify(num, notificationBuilder.build());

 Intent resultIntent = null;

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.mipmap.ic_launcher)
                        .setContentTitle(context.getString(R.string.app_name))
                        .setAutoCancel(true)
                        .setContentText(message);




        resultIntent = new Intent(context,Activity.class);

        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        // Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack(Activity.class);
        // Adds the Intent that starts the Activity to the top of the stack
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(
                        5,
                        PendingIntent.FLAG_UPDATE_CURRENT
                );
        mBuilder.setContentIntent(resultPendingIntent);
        NotificationManager mNotificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        // mId allows you to update the notification later on.
        mNotificationManager.notify(pushId, mBuilder.build());

Answer 3

嘗試這個：

 Intent intent = new Intent(this, NotificationActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_stat_name)
            .setContentTitle("Title")
            .setContentText(messageBody)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

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

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());

Firebase通知

1.如果您是通過Firebase控制台發送通知，firebase會像這樣向您的消息中添加一個通知對象

{
   //..
    "notification" : {
      "body" : "message body sample text",
      "title" : "notification Tittle",
      "icon" : "icon information sample"
    }
   //..
  }

1）如果您的通知包含此通知有效負載，並且如果您的應用程序處於后台 ，

• 通知將發送到設備的系統托盤。 用戶點擊通知會默認打開應用啟動器。

2）如果您的通知包含此通知有效負載 + 數據有效負載，並且如果您的應用程序處於后台 ，

• 通知將傳遞到設備的系統托盤，數據有效載荷將在啟動器活動的意圖范圍內傳遞。

3）如果您的通知僅包含數據有效載荷 （ {data" : {"body" : "message body sample text","title" : "notification Tittle","icon" : "icon information sample"} ），並且您的應用程序然后在背景或前景中

• Firebase消息處理程序的OnMessageReceived（）方法被調用，我們可以編寫代碼來顯示此方法中的通知。

因此，如果您想在每次收到通知時都執行OnMessageReceived()方法，則應始終從服務器端傳遞僅數據有效負載。否則， OnMessageReceived()將不會執行，Firebase將處理顯示事物的通知。
