Dismiss activity shown with FLAG_SHOW_WHEN_LOCKED

I'm showing an activity in lockscreen from a background service while the device is locked when the user is within a certain area (GPS obtained).

The activity has this code:

    protected void onCreate(Bundle savedInstanceState) {
        ...
        getWindow().addFlags(
            WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD|
            WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED|
            WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
        ...
    }

And it is being called from the service like this:

    if (inArea){
        PowerManager pm = (PowerManager)mContext.getSystemService(Context.POWER_SERVICE);
        if (pm.isScreenOn()==false){
            Intent wakeIntent = new Intent(mContext, mClass);
            wakeIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            mContext.startActivity(wakeIntent);
        }
    }

When the user exits the area the activity should no longer be seen in lockscreen. But I cant get that.

I tried this when the user's GPS is outside the area:

    if (!inArea){
        android.os.Process.killProcess(android.os.Process.myPid());
        System.exit(1);
    }

But the activity remains present in the lockscreen.

Any suggestion on how to achieve this?

Have the service broadcast when the user exits the are. Have the activity register a broadcast receiver for that broadcast. If it receives that broadcast, have it finish() itself.

Or a dozen variations on this- they all boil down to have the application get informed when its no longer in the area and kill itself.
