I am creating an Android app. I have set up the notification system to open a specific activity/class on notification click. When my App is totally closed and I send a notification and when I click on it opens the correct activity like this example:

App is not running > Notification comes in > Click on the notification > Activity_T opens.

BUT, when my app is running and I get a notification and when I click on it to open the Activity_T it doesn't it loads MainActivity instead.

The flags I use are the follow

    Intent intent = new Intent(mContext, (Class<?>) activityToLaunch);

    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);

    intent.putExtra("tt", title);

    intent.putExtra("bd", body);

    mContext.startActivity(intent);

I want to open Activity_T on notification click either the app is running or not. How to force open Activity_T whenever I click on the notification.

I send notification from receiver onReceive method. When click on notification,I open an activity,even the app was killed. I used like that

Intent notificationIntent = new Intent(context, MainActivity.class);

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



NotificationCompat.Builder mBuilder =

    new NotificationCompat.Builder(context, "")

        .setSmallIcon(R.drawable.my_ic)

        .setContentTitle(title)

        .setContentText(msg)

        .setContentIntent(contentIntent);

Try below code...Change YOUR_ACTIVITY.CLASS with your activity name...

@RequiresApi(api = Build.VERSION_CODES.KITKAT)

@Override

public void onMessageReceived(RemoteMessage remoteMessage) {

Intent intent=new Intent(this,YOUR_ACTIVITY.CLASS);

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

PendingIntent pendingIntent=PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_ONE_SHOT);//new PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_ONE_SHOT);

NotificationCompat.Builder notificationBuilder= new NotificationCompat.Builder(this);

notificationBuilder.setContentTitle("FCM NOTIFICATION");

notificationBuilder.setContentText(Objects.requireNonNull(remoteMessage.getNotification()).getBody());

notificationBuilder.setAutoCancel(true);

notificationBuilder.setSmallIcon(R.mipmap.ic_launcher);

notificationBuilder.setContentIntent(pendingIntent);

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

assert notificationManager != null;

notificationManager.notify(0,notificationBuilder.build());

}
