android - Which method is preferred to override onBackPressed? -

first case

public boolean onkeydown(int keycode, keyevent event) { if (keycode == keyevent.keycode_back) {

second case

onbackpressed();

which case improve override backkeypress event?

if want grab press prior 2.0, can utilize onkeydown method so:

@override public boolean onkeydown(int keycode, keyevent event) { if (keycode == keyevent.keycode_back && event.getrepeatcount() == 0) { //do on press } homecoming super.onkeydown(keycode, event); }

interestingly, if override both onbackpressed , onkeydown, both grab press onkeydown catching first.

if phone call super.onkeydown in onkeydown above, onbackpressed method fire. if not phone call super.onkeydown onbackpressed never called.

unless have specific reason target below 2.0, there isn’t much of reason bother.
