Example of making use of the Application context using @Component.Builder in AppComponent class (new way)

AppComponent.java

@Singleton
@Component(
        modules = {
                AndroidInjectionModule.class,
                AppModule.class,
                ActivityBuildersModule.class
        })
public interface AppComponent extends AndroidInjector<BaseApplication> {

    @Component.Builder
    interface Builder {

        @BindsInstance
        Builder application(Application application);

        AppComponent build();
    }
}

AppInjector.java

public void init(BaseApplication app){
  appComponent = DaggerAppComponent.builder()
      .application(app)
      .build();
  appComponent.inject(app);
}

AppModule.java

@Module
public class AppModule {

    @Singleton
    @Provides
    Drawable getDrawable(Application application){ // application is available here
        return ContextCompat.getDrawable(application, R.drawable.ic_launcher_background);
    }

}

MainActivity.java

@Inject
Drawable getDrawable;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
  if(getDrawable == null){
    Log.d(TAG, "onCreate: drawable is null.");
  }
  else {
    Log.d(TAG, "onCreate: drawable is NOT null.");
  }
}
