How does one listen for progress from Android SyncAdapter?

Question

I recall reading about a broadcast receiver interface from the sync adapter or some ResultReceiver of sync progress events. Is there something built into the SyncAdapter pa

Answer 1

What works:

The method suggested in a 2010 Google IO session, Developing Android REST client applications is to place columns into your ContentProvider as tags to indicate that a record is being fetched or placed or etc. This allows a per-row spinner (or other visual change) to be placed in your UI. You might do that through a custom CursorAdapter that drives a ListView. Your ContentProvider is on the hook to make the flags change as needed.

What doesn't:

You can also use a SyncStatusObserver -- Which is pretty much useless since it responds to every change of status, not just your specific account/contentauthority pair, and really doesn't tell you much anything at all other than that a change occured. So, you can't tell what is being synced, and you can't distinguish "start of sync event" from "end of sync event". Worthless. :P
