Any idea how I can get to the bottom of this? I am wondering if this error message means that the list view ask for the number of rows in the list adapter, but during the rendering of the list this number changes (is reduced). That code is not in my hand though.
How would I deal with that? Currently I change the database on a background thread, send a notification (notification in the generic sense, not an Android notification) afterwards and the listeners that want to change the UI (like refreshUI() form below) use runOnUiThread() to process the event.
