You need to clear the back-stack where you are using the Intent
Like this:

Intent intent = new Intent(FirstActivity.this,SecondActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
finish();

Here FirstActivity will get cleared from back-stack and will be finished. Also you will be navigated to SecondActivity. So when you press back button from SecondActivity, it will close the app.
Hope this will solve your problem.
