Can you post the relevant part of the code and logcat with the exception? – Szymon Mar 19 '14 at 02:34

You need to educate yourself on the Android Activity Lifecycle, so that you understand what is happening when you relaunch the activity. If you don't want the query to be rerun on activity start you need to handle recreating your app correctly.
Finally, for your bulk insert problem, if your app is freezing, that is an indication that you are doing the loading on the UI thread. You should be doing this using the LoaderManager and probably an AsyncTaskLoader to load this data off of the UI thread.
