Hi Guys, There are many occasions when you would like to prevent or override default back button event for android devices. One of them is say when your present user with a login screen and they log in successfully and then you push a target view to the view stack, what if someone press hardware back button? Some questions that may arise in this situation is if you are offering in built session support or something equivalent to "remember me" functionality what happens?
