Android Architecture Components - communication between Activity/Fragment and Service/IntentService










1















The answer to this question is providing me with a marvelous guide to how to use services in the Android Architecture Components/Jetpack environment.



It suggests that IntentServices should just plug into ViewModels via Repositories, as if they were any other data source, like a web service.



But neither that answer nor the Jetpack guide upon which it's based have much information about the so-called "Remote Data Source" object that would start and bind to the service, observe its LiveData and cascade it back up to the Repository.



What is it? An ordinary Java object that gets injected into the Repository? A singleton? Some special Lifecycle-aware subclass?



Where does it get the context it needs to start the service?



Is there example code you can point me to? If not, could you just sketch out the basics of what that would look like, including how its lifecycle would be linked to the lifecycle of the service itself, for newbies like me?



enter image description here



Thanks in advance!

          • Are you talking about the "RemoteRepository" that the blog refers to? I can't see an implementation of it, just references to it.

          Why do you want to use the service? Remote Data Source typically means a layer that fetches data from your web back end API using a library such as Retrofit. You don't need a Service for that.
