How to know when sync is finished?

Question

I have implemented a sync adapter and I want to get a callback when it finishes in my activity. I have tried using ContentResolver.addStatusChangeListener, but I am only get

One solution that I have found is to ditch the ContentResolver completely, and implement my own broadcast. Basically, add this in the sync adapter, at the end of onPerformSync:

Intent i = new Intent(SYNC_FINISHED);
sendBroadcast(i);

And this in the activity:

@Override
protected void onResume() {
    super.onResume();
    registerReceiver(syncFinishedReceiver, new IntentFilter(DataSyncService.SYNC_FINISHED));
}

@Override
protected void onPause() {
    super.onPause();
    unregisterReceiver(syncFinishedReceiver);
}

private BroadcastReceiver syncFinishedReceiver = new BroadcastReceiver() {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d(Const.TAG, "Sync finished, should refresh nao!!");
    }
};

This seems to work just fine, however I was hoping to find something in the SDK that directly notify me when a sync is finished.
