Put below code on the onCreate() of launcher activity-

final Intent intent = getIntent();
if ((intent.getFlags() & Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT) != 0
    && intent.hasCategory(Intent.CATEGORY_LAUNCHER)
    && intent.getAction() != null
    && intent.getAction().equals(Intent.ACTION_MAIN)) {
  finish();// finish this launcher activity
  return;
}
