Answer 1

try this:

private void setNotification(String notificationMessage) {  //**add this line** int requestID = (int) System.currentTimeMillis();  Uri alarmSound = getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); mNotificationManager  = getApplication().getSystemService(Context.NOTIFICATION_SERVICE);  Intent notificationIntent = new Intent(getApplicationContext(), NotificationActivity2.class);  //**add this line** notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);   //**edit this line to put requestID as requestCode** PendingIntent contentIntent = PendingIntent.getActivity(this, requestID,notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);  NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext()) .setSmallIcon(R.drawable.logo) .setContentTitle("My Notification") .setStyle(new NotificationCompat.BigTextStyle() .bigText(notificationMessage)) .setContentText(notificationMessage).setAutoCancel(true); mBuilder.setSound(alarmSound); mBuilder.setContentIntent(contentIntent); mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());  }
