I created a sqlite database to store playlists for a media player I am developing because of extended feature (rather than using the Content Provider). It works perfectly on the 1.6 emulator but FCs on anything higher than 2.0… what has changed that I need to know about as far as opening databases in SDK 2.0+? Here is the logcat.

god I hate this stupid “enter code here”… why can’t stackoverflow just use tags like a normal syntax highlighter.
Are you sure the database is copying correctly, it appears as though the table doesn’t exist?
Have you tried copying the data off the phone after execution via DDMS and exploring it to see if the schema is correct?
