Dependency injecting into a Android Service

• So I ran into a problem where I wanted to do some dependency injection inside a Android Service. I initialy thought we could do constructor injection just like any other class. However, that is not is the case. Thanks to THIS stackoverflow question and looking at the services of several open source Android projects, I have learned that we must do dependency injection into a Service like so:

@AndroidEntryPoint
class BillingService: Service() {

  @Inject lateinit var billingClientWrapper: BillingClientWrapper

}

• Note how the Service is annotated with @AndroidEntryPoint and we add @Inject lateinit to whatever we want to inject.

Conclusion
