Android通知意图未启动所述活动和通知声音问题

Question

嗨，我正在使用Firebase Cloud Messaging的应用程序上工作，并且我尝试在应用程序使用Firebase Cloud Messaging接收消息时显示通知。
当应用程序运行时

1. 我可以听到通知声
2. 当我点击通知时，在我的情况下，它使我进入正确的活动NotificationActivity.java

现在，当关闭App时，它不会在后台运行（这些主要问题需要解决，并且需要针对这种不自然的行为进行解释）

1. 我可以看到通知，但听不到通知声音。
2. 当我点击通知时，它不会打开NotificationActivity.java而是打开Splash.java ，这是默认/启动器活动

以下是代码片段。

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());

尝试这个：

 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.如果您是通过Firebase控制台发送通知，firebase会像这样向您的消息中添加一个通知对象

{
   //..
    "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负载，并且如果您的应用程序处于后台 ，

• 通知将发送到设备的系统托盘。 用户点击通知会默认打开应用启动器。

2）如果您的通知包含此通知有效负载 + 数据有效负载，并且如果您的应用程序处于后台 ，

• 通知将传递到设备的系统托盘，数据有效载荷将在启动器活动的意图范围内传递。

3）如果您的通知仅包含数据有效载荷 （ {data" : {"body" : "message body sample text","title" : "notification Tittle","icon" : "icon information sample"} ），并且您的应用程序然后在背景或前景中

• Firebase消息处理程序的OnMessageReceived（）方法被调用，我们可以编写代码来显示此方法中的通知。

因此，如果您想在每次收到通知时都执行OnMessageReceived()方法，则应始终从服务器端传递仅数据有效负载。否则， OnMessageReceived()将不会执行，Firebase将处理显示事物的通知。
