Dagger 2.10 Android subcomponents and builders

Question

Using the new (in 2.10) dagger.android classes, I\'m trying to inject things using a Subcomponent that depends on other Modules, and, therefore, has a Builder with setters f

Answer 1

that does work, but it's unnecessary. the seedInstance method provides the activity instance into the graph, so you can have MyActivityModule with no state, and just request MyActivity in your @Provides methods.

class MyActivityModule {
  @Provides
  static SomethingDerivedFromMyActivity providesMethod(MyActivity myActivity) {
    return myActivity.somethingDerived();
  }
}

Doing this saves the module instance and allows the generated factories to be leaner.
