Answer 1

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();
}
