问题 I have intent service in my app. This service has some job to do - uploading some files. It runs only when there is something to do.

More precisely: for the contacts that I entered into my contact book by hand, the Intent.ACTION_PICK has no trouble finding and returning them to the app, i.e. cursor.moveToFirst() is true.
