Allow Hilt injection first without BaseFragment or BaseActivity

Thanks for the great tools! I'm not really in trouble, so it's okay for reference only.

To inject first, you need to prepare an inject method with BaseFragment etc.

https://github.com/google/dagger/releases/tag/dagger-2.33

abstract class BaseActivity extends FragmentActivity {
  @Override
   protected void onCreate(Bundle savedInstanceState) {
    inject(); // <- This will force early injection.
    foo.doSomething();
    super.onCreate();    
  }

  // An inject method to be overridden by the Hilt generated class.
  protected void inject() {
    throw new UnsupportedOperationException();
  }
}

For example, how about providing an interface like HiltInjectable?

Generated code

public abstract class Hilt_PlayerFragment extends Fragment implements GeneratedComponentManagerHolder,
   **HiltInjectable** {
....
   @Override
   protected void inject() {
...
   }

Library code

interface HiltInjectable{
    fun inject()
    companion object {
        fun inject(any: Any){
            (any as HiltInjectable).inject()
        }
    }
}

App code

@AndroidEntryPoint
class PlayerFragment : Fragment(R.layout.fragmenet_player) {
    @Inject
    lateinit var custom: FragmentModule.Custom

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        HiltInjectable.inject(this)
        println("custom:" + custom)
        super.onViewCreated(view, savedInstanceState)
    }
}
