Exception: android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0

Category: Index error

Root cause: The cursor in Method "uk.ac.cam.cl.dtg.android.barcodebox.activities.Viewer.onContextItemSelected(at line 98)" has not check if the access line exists or not, missing "if (cursor.moveToFirst())" probably.

Description: When querying database, it may failed, better to check whether the return value is null or not; Besides, the cursor is at index -1 by default, call "MoveToFirst()" before data access and also check if it's empty. \nNote: "null" and "empty" are different.

Fix solution:

    1: Use if((cursor != null) and (!cursor.MoveToFirst())) to check.

    2: Use while(!cursor.MoveToNext()) to iterate when using loop clause.
