int MyNameColumn = c.getColumnIndexOrThrow("drawingName");
c.moveToFirst();
if (c != null) { .....}
1. You are checking for null after using it above twice which is
redundant......
2. Catch the exception
3. If catching and you are getting a NullPointer then use Lod.e(TAG,
exception.getMessage() + ""); // nullpointers, leaving out the "" will
break the code.
Hope this helps,
