Android dagger: No injector factory bound

问题:

I'm using dagger 2 on my android project. At first I'm use only one component in the name of AppComponent and my project works fine. Then I split AppComponent and create these component: ActivityComponent, ContentComponent for different scope. When I was build my project I getting an error:

Caused by: java.lang.IllegalArgumentException: No injector factory bound for Class<project.presenter.activity.MainActivity>

Another problem is If I add ActivityScope to ActivityComponent I'm getting this error:

Error:(4, 1) error: @project.di.ContentScope project.di.ContentComponent depends on more than one scoped component:
