You could either cache the results locally and return them when asked, or better you could document that using your provider takes significant time and that users should do the calls asynchronously. In general it's good for applications to do content provider call asynchronously, since even local database operations could become pretty expensive. See the AsyncQueryHandler class, which handles much of the thread for you when trying to do async queries, or you could also use the wonderful UserTask class in the calling app to do the query asynchronously. Also, note that CursorAdapter has the changeCursor() method, which helps with doing async things. In onCreate() you can create your CursorAdapter and pass null for the cursor and then call changeCursor(newCursor) when the async query completes. changeCursor() takes care of closing the old cursor for you, which can make managed cursor unhappy, so you'll either have to manage the cursor yourself or call stopManagingCursor(adapter.getCursor()) before calling changeCursor().
