Hi Dianne Hackborn,
Thanks for your reply........
Fine.. I'll follow your inputs. Will you please tell the procedure to
create Content Provider..
ie, 1. Extent ContentProvider
2. Add <Provider> tag
3. How can I assign the CONTENT_URI for my own content provider
like that..
Since, I've tried to creating Content Provider step by step. But I
can't get the output. :(
If you've some samples or procedure in detailed manner surely it will
help me lot ...
Thanks for your time..
Yasmin
