Description

Sentry Issue: NOVA-VIDEO-PLAYER-38

IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifyDataSetChanged() when its content changes. [in ListView(2131362362, class android.widget.ListView) with Adapter(class com.archos.mediacenter.video.utils.ScraperResultsAdapter)]

Contributor guide

Research direction
Investigate the stack trace to identify where the adapter is being modified from a background thread. Ensure that all adapter modifications (e.g., adding/removing items) are performed on the UI thread using runOnUiThread or Handler, and call notifyDataSetChanged afterwards.
