How to create activity context dependent object in dagger?

Question

I have a situation, I have injected all objects using Dagger 2, But in one situation I am unable to rectify how to inject the object.

Following is the situation

mPager.setAdapter(new MyPagerAdapter(this));

Now in the above statement, I have to inject the MyPagerAdapter object using Dagger, but it requires current activity context.

So how to forward the activity context to the Dagger module?

@EpicPandaForce - Can you please add some code resolving the above situation will help. — Chetan Gaikwad, Dec 09 '16 at 11:02
`@Module @ActivityScope public class MyModule { private Activity activity; public MyModule(Activity activity) { this.activity = activity;} ...` — EpicPandaForce, Dec 09 '16 at 11:11
Does someone want to turn this into an answer? I don't think this exact question has been asked before. — David Rawson, Dec 09 '16 at 20:00

(turning @EpicPandaForce's comment into an answer)

You can write a module that takes an Activity in its constructor parameters like this:

@Module
@ActivityScope 
public class MyModule {
    private final Activity activity;

    public MyModule(Activity activity) {
        this.activity = activity;
    }

    @Provides
    @ActivityScope
    Activity activity() {
        return activity;
    }
}
