I keep hitting something which makes me wonder if I'm doing something wrong.
I have a few Activities, each of which has a ExpandableList and a ResourceCursorTreeAdapter which is given a cursor from Activity.managedQuery when the adapter is created in the onCreate method of the activity. There is also a service which updates the data that the ResourceCursorTreeAdapter has a Cursor to via the datas ContentProvider. When there is no data in the provider the service may download around 100 records and perform inserts. The ContentProvider does fire a notifyChange on each insert. If I run the application in the emulator and switch between the activities whilst the ContentProvider is populated I can sometimes trigger the exception at the end of this email. If I wait until everything has been populated I can't trigger the problem. The confusing part is that the stack trace doesn't doesn't reference my code in any way. Anyone have any suggestions?
