Question

I have two activities, say LoginActivity which contains a login UI and HomeActivity. On HomeActivity, I have put a button that calls the method below:

public void goToLoginPage(View view) {
    finish();
    super.finish();     
    Intent i = new Intent(HomePageActivity.this, LoginActivity.class);
    startActivity(i);
}

But when I click this button, the login page with the last entered credentials appears once again. Instead I want a fresh login page or at least without last entered credentials.

Answer 1

Based on your information, LoginActivty is the starting activity and that activity, after a successful login, starts the HomePageActivity. To return to the LoginActivity, you can execute the following:

Intent i = new Intent(HomePageActivity.this, LoginActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);
finish();

This will only work if, when LoginActivity launched HomePageActivity, it did not call finish() on itself (ie: the instance of LoginActivity must still be present in the activity stack). Also, the launchMode of LoginActivity must be either default (ie: not specified at all) or “standard”.

This will result in the current instance of LoginActivity being finished and a new instance of LoginActivity will be created and the onCreate() method will be called.
