Do your query and moveToFirst() call in an AsyncTask, or otherwise get that work off of the main application thread. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 3.1 Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
