android ObjectGraph in new version of Dagger2

i'm trying to update this below code to dagger2, but i get error for ObjectGraph:

import dagger.ObjectGraph;
public class App extends Application {
    private static App instance;
    private ObjectGraph objectGraph;
    public App() {
        instance = this;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        objectGraph = ObjectGraph.create(new AppModule());
    }

    public static void injectMembers(Object object) {
        getInstance().objectGraph.inject(object);
    }

    public static <T>T get(Class<T> klass) {
        return getInstance().objectGraph.get(klass);
    }

    public static App getInstance() {
        return instance;
    }
}

how can i update that to and which class must be use instead of ObjectGraph?

injectMembers used in this class

public class MyJobManager extends JobManager {
    public MyJobManager(Context context) {
        super(context, new Configuration.Builder(context)
                .injector(new DependencyInjector() {
                    @Override
                    public void inject(BaseJob baseJob) {
                        App.injectMembers(baseJob);
                    }
                })
 .build());
    }
}

now how can i inject with component?

my component:

@ActivitiesScope
@Component(dependencies = GithubApplicationComponent.class)
public interface ApplicationComponent {
    void inject(ActivityRegister activityRegister);

    void inject(ActivityStartUpApplication activityStartUpApplication);

    void inject(GetLatestRepositories getLatestRepositories);
}

Dagger 2 doesn't use an ObjectGraph. It doesn't use anything as its replacement. Dagger1 did injection at runtime via reflection and used the ObjectGraph to provide that functionality. Dagger 2 does injection at compile time, thus it doesn't need a runtime object to represent the graph. Instead you'd want to build a component that links the modules you with to provide. You can then inject using that component.

See https://google.github.io/dagger/dagger-1-migration.html for more details.
