It's good you specify that queryBroadcastReceivers will not include receivers registered with Context.registerReceiver() because the documentation says "Retrieve all receivers that can handle a broadcast of the given intent." on page http://developer.android.com/reference/android/content/pm/PackageManager.html#queryBroadcastReceivers%28android.content.Intent,%20int%29.
