Hey I think it May Help you to get your solution :
Just write this code on your button EXIT click.
Intent intent = new Intent(getApplicationContext(), MainActivity.class); intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); intent.putExtra("LOGOUT", true); startActivity(intent);
And in the **onCreate()** method of your MainActivity.class write below code as a first line,
if (getIntent().getBooleanExtra("LOGOUT", false)) { finish(); }
