During building app module, the following error is thrown:
:app:compileDebugJavaWithJavac
/app/build/generated/source/apt/debug/pl/kibao/contributesandroidinjector/ContributesAndroidInjectorModule_ContributeMainActivityInjector.java:21: error: @dagger.android.ActivityKey methods should bind dagger.android.AndroidInjector.Factory<? extends android.app.Activity>, not dagger.android.AndroidInjector.Factory<? extends android.app.Activity>. See https://google.github.io/dagger/android
abstract AndroidInjector.Factory<? extends Activity> bindAndroidInjectorFactory(
^
1 error
Whereas almost the same app-generated-injector modules works fine.
The only difference is that, it uses generated ContributesAndroidInjectorModule_ContributeMainActivityInjector
class instead of ContributesAndroidInjectorModule with annotated method.
