You can also do logout by starting the LoginActivity. Example is shown below and is for when you select the Log Out button in the menu.

 @Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    switch (id) {
        case R.id.action_logout:
            LoginActivity.username.setText("");
            LoginActivity.password.setText("");
            Intent logout = new Intent(getApplicationContext(), LoginActivity.class);
            startActivity(logout);
            return true;
    }
}
