I'm making a game and if the activity is left in any way by the user (back or home key pressed), the activity needs to end the game by posting to a script and ending the activity.

I can detect if the back key is pressed, however, I cannot find any valid method to detect if the home key is pressed. I can't just end the game in the Activity_Pause method because let's say the user receives a phone call mid-game.

I understand you can't trap the event, however, has anyone found a way to see if the activity was left by the user instead of something else like a phone call sending it to the background.

Ok here is the work around if you insist. Android next version may just close the loophole.

boolean mKeyPress;

boolean mUserLeaveHint;

@Override

public boolean onKeyDown(int keyCode, KeyEvent event)

mKeyPress = true;

return super.onKeyDown(keyCode, event);

@Override

protected void onUserLeaveHint()

super.onUserLeaveHint();

mUserLeaveHint = true;

@Override

protected void onPause()

super.onPause();

if (!mKeyPress && mUserLeaveHint)

// HOME_KEY is pressed

Looks like a duplicate of this one
