eclipse - Override back button in app android -

-

made application in android, buttons handled, web site?

if so, these buttons programmed button or whether default applications?

thanks...

android requires existence of button (along power , volume control). either hardware button or software, visible navigation bar.

in general default handling of button work in instances. go through app's previous activities , close app once reaches end of stack. same can configured work fragment stacks too.

you can opt override default implementation though if choose to. in activity want manually control action when user presses back:

@override public void onbackpressed() {     // custom actions }
