[android-developers] Handling ACTION_SCREEN in a widget

Hi,

I'm doing a widget that needs to be update on screen_on or on
user_present. As I'm not hable to register a BroadcastReceiver inside
the widget I'm doing it in a Service that is triggered by the widget
like this:

Widget.java:
    @Override
    public void onEnabled(Context context) {
        super.onEnabled(context);
        context.startService(new Intent(context,
WidgetService.class).setAction(WidgetService.ACTION_WIDGET_START));
    }

WidgetService.java:
    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);

        String action = intent.getAction();
        Log.d(LOG_APP,"WidgetService onStart: "+action);

        if (ACTION_WIDGET_STOP.equals(action)) {
            this.unregisterReceiver(mReceiver);
            stopSelf();
            return;
        } else if (ACTION_WIDGET_START.equals(action)) {
            // register receiver that handles screen on and screen off logic
            IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
            this.registerReceiver(mReceiver, filter);
            return;
        }

The problem is that when I try to register the receiver I get the
error that the service has leaked IntentReceiver because it was
already registered. Ive checked and no duplicate registration was done
in my code.

Do you have any idea what I'm overlooking?

Thanks,
PMD
