Does BroadcastReceiver.onReceive always run in the UI thread?

Question

In my App, I create a custom BroadcastReceiver and register it to my Context manually via Context.registerReceiver. I also have an AsyncTask<

Answer 1

As the previous answers correctly stated onReceive will run on the thread it's registered with if the flavour of registerReceiver() that accepts a handler is called - otherwise on the main thread.

Except if the receiver is registered with the LocalBroadcastManager and the broadcast is via sendBroadcastSync - where it will apparently run on the thread that calls sendBroadcastSync.
