That won't work for you.

Because, service classes are without View. You cannot have XML for your service class.

From the documentation:

A Service is an application component that can perform long-running operations in the background, and it doesn't provide a user interface.

To handle your recyclerView in View(Activity/Fragment) from any other class (in your case from NetworkBroadcast class), you need to use interface.
