I'm sorry I didn't mean to post the same question so many times...it's just that in my case it took 3 days to see the first query posted!
In addition I would like to add to my query saying that the Service apk that I made has only a <service> component. I heard that an Android app requires atleast 1 <activity> component. Can anyone please help confirm this?
