ContentProvider class design is very good, transport as a member exists, to complete the function of binder, a bit like the combination mode, the completion of the forwarding/communication function encapsulated as an internal class, easy to forward external calls to external classes, this design is widely used in Android, Merging transport with ContentProvider will make the class functionality too complex.
