Hello,
when I run your sample, I get the following crash:

Please advise,

想问下如果我想在dialog中注入activity类型的context，我该怎么提供这个context

Hi, Would you be willing to show how to create a feature with multiple activities and a resource shared only with the activities of this feature ?

Hi,

It would be great to see a repository layer managed by dagger in your example.
The FeaturePresenter would use an ObjectRepository to fetch data.
ObjectRepository would be singleton.

Best regards
Laurent

I think we can change this:

@Provides @Named("someId") static String provideSomeId(FeatureActivity featureActivity) {
        return featureActivity.someId;
}

to this:

@Provides @Named("someId") static String provideSomeId(FeatureActivity featureActivity) {
        return featureActivity.getIntent().getStringExtra(EXTRA_SOME_ID);
}

So we don't need to save someID in the activity. What do you think?
