Android sendBroadcast() followed by finish()

Question

I am stuck on something that seems to be a thread synchronization problem. I have two classes:

AppLayout that extends Activity SettingsPart that extends Fragment and implements some Listeners

When the settings are applied successfully I would like to send a Broadcast and finish the Activity, so the code in SettingsPart.java looks like:

((AppLayout) getActivity()).sendBroadcast(intent); ((AppLayout) getActivity()).finish();

The Activity closes as expected, but no broadcast is sent. If I remove the call to finish() the broadcast is sent successfully.

Is there any smart way to wait for the broadcast to be sent before closing the activity?

Answer 1

The Activity is receiving the broadcast, it just can't do anything with it (because the activity is finishing immediately). Instead of calling finish() SettingsPart.java, I would call finish() from wherever you're processing the broadcast within the Activity. Just be careful that you finish the activity in all cases and don't leave it unfinished forever.
