After Logging In, I'd like to exit the app with the back button, not re-enter the Login screen. How do I do so?

Hi Joshua

If you would never like to navigate back to the login activity simply use the line of code

finish();

after your call to startAcitivty(). This will close the activity and won't be available to navigate back to without restarting the app or specifically calling the activity later in your code. Another more complex and probably unnecessary way would be to implement the onBackPressed() method (don't forget to use the @override annotation) inside the new method and alter how you would like the back button press to be handled.

My personal preference for these things is to simply finish the login activity, if I do need to use this activity again I can simply call it up again using startActivity().

Hope this helps Daniel

When starting the MainActivity after login you want to add intent flags:

  //Once signed in go to MainActivity
  Intent intent = new Intent(LoginActivity.this, MainActivity.class);
  intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
  startActivity(intent);
