CustomView dependency injection with dagger 2 (within activity scope)

Question

My question is similar to this.

So for instance, I have a LiveData implementation:

public class CustomLiveData extends LiveData

        

Answer 1

Your Dagger hierarchy looks like this: appcomponent -> activitycomponent

You try to inject activity context inside view, that depends on appcomponent directly.

It's not possible since there is no method that could provide activity context in appcomponent. Instead, inside view, you should retrieve activity (for example using getContext), extract activitycomponent from it and only then inject CustomLiveData.
