Answer 1

Few things you could try:

1. Try opening it with SQLiteBrowser to see that it's not corrupt
2. Make sure it's in the right path
3. Ensure it has the right permissions for read/write
4. Ensure you have this permission in your manifest file <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
