Detect home button press in android

Question

This has been driving me nuts for a while now.

Is there any way of reliably detecting if the home button has been pressed in an android application?

Answer 1

onUserLeaveHint();

override this activity class method.This will detect the home key click . This method is called right before the activity's onPause() callback.But it will not be called when an activity is interrupted like a in-call activity comes into foreground, apart from that interruptions it will call when user click home key.

@Override
protected void onUserLeaveHint() {
    super.onUserLeaveHint();
    Log.d(TAG, "home key clicked");
}
