Answer 1

Give activity name to pending intent ....

      Intent intent = new Intent(this, NotificationCheck.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);
    notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("App Name")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setStyle(new NotificationCompat.BigTextStyle().bigText(messageBody))
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

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

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

See below code. I am using that and it is opening my HomeActivity.

NotificationManager notificationManager = (NotificationManager) context
        .getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
//change HomeActivity.class which activity you want to open after clicking notification
Intent notificationIntent = new Intent(context, HomeActivity.class);

notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
        | Intent.FLAG_ACTIVITY_SINGLE_TOP);

PendingIntent intent = PendingIntent.getActivity(context, 0,
        notificationIntent, 0);

notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);

change HomeActivity.class which activity you want to open after clicking notification.. hope it will work...

You need to pass the required activity as intent, not the MainActivity

Answer 4

/**
 * Method checks if the app is in background or not
 */
public static boolean isAppIsInBackground(Context context) {
    boolean isInBackground = true;
    ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    if (Build.VERSION.SDK_INT > Build.VERSION_CODES.KITKAT_WATCH) {
        List<ActivityManager.RunningAppProcessInfo> runningProcesses = am.getRunningAppProcesses();
        for (ActivityManager.RunningAppProcessInfo processInfo : runningProcesses) {
            if (processInfo.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
                for (String activeProcess : processInfo.pkgList) {
                    if (activeProcess.equals(context.getPackageName())) {
                        isInBackground = false;
                    }
                }
            }
        }
    } else {
        List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1);
        ComponentName componentInfo = taskInfo.get(0).topActivity;
        if (componentInfo.getPackageName().equals(context.getPackageName())) {
            isInBackground = false;
        }
    }

    return isInBackground;
}

You can check app is in the background or not and then in MyFirebaseMessagingService class you can use this method in for handle message and handle the notification.

private void handleNotification(String message) {
    if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
        // app is in foreground, broadcast the push message
        Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION);
        pushNotification.putExtra("message", message);
        LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);

        // play notification sound
        NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext());
        notificationUtils.playNotificationSound();
    }else{
        // If the app is in background, firebase itself handles the notification
    }
}

I hope it helps you.
