I've double checked my code and found I'm doing this slightly differently, although the method above should also work.
Strike "Register" broadcast receiver in the manifest - this seems to be meerly a declaration of the receiver. No intent filters; I check the specific event types _ON/_OFF in the receiver's onReceive() method. The key: I register the BroadcastReceiver manually, using Context.registerReceiver(BroadcastReceiver receiver, IntentFilter filter) On Jul 19, 8:22 pm, jiaoni <[email protected]> wrote: > Thanks, JP.
