Android: Intent Flag to destroy activity and start new one

Question

So I have a Login Activity This Activity inflates a login.xml layout which has a USER_NAME and PASSWORD EditText Views, when I enter the Username and Password and click the Logi

Answer 1

You have 2 choices:

1 - Kill the login activity after a successful login

Intent loginIntent = new Intent(getActivity(), Login.class);
    loginIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    getActivity().startActivity(loginIntent);
finish();

2 - Empty the values then start new activity

edittext_username.setText("");
edittext_password.setText("");

Answer 2

If you are supporting only API levels 11+, you should be able to use FLAG_ACTIVITY_CLEAR_TASK. This will finish all existing Activities in all tasks and create a new instance of the Login activity.
