AFAIK, there is no way of overriding the recent apps button.

I got around this by change onPause app behavior to start an alarmmanager. There may be a more elegant solution, but this works.

First, create repeating alarmmanager setupAlarm(seconds)( full details here and here, note I used repeating alarm rather than one off, think both will work though) that starts your activity

then change onPause to set a 2 second alarm, so whenever someone selects the recent apps button on the nav bar, a 2 second 'alarm' to start mainActivity is set.

@Override
public void onPause() {
    setupAlarm(2);
    finish(); //optional
    super.onPause();

}

So with this and the above, any attempt to use the navigation buttons or restart the app results in app starting. So until I get round to investigating the 'kiosk' style roms this is a very good compromise.
