Edit Question
Title
Body
I'd like to warn the user if the back press is going to finish the last activity on the stack, thereby exiting the app. I'd like to pop up a little toast and detect a 2nd back press within the next few seconds and only then call finish() . I already coded the back press detection using onBackPressed() , but I can't find an obvious way to see how many activities are left on the back stack. Thanks.
