Dagger Hilt doesn't work with Dynamic Feature Modules.

See original GitHub issue

Versions:

Dagger 2.28
Dagger Hilt 2.28-alpha

I tried Dagger Hilt with Dynamic Feature Modules. Here is a sample project: https://github.com/yamasa/Hilt_DFM

But, unfortunately, Dagger Hilt doesn’t work for Activities in DFM. It crashes with the following exception:

Caused by: java.lang.ClassCastException: com.example.hilt_dfm.DaggerMyApplication_HiltComponents_ApplicationC$ActivityRetainedCImpl$ActivityCImpl cannot be cast to com.example.hilt_dfm.feature.DfmActivity_GeneratedInjector
    at com.example.hilt_dfm.feature.Hilt_DfmActivity.inject(Hilt_DfmActivity.java:60)
    at com.example.hilt_dfm.feature.Hilt_DfmActivity.onCreate(Hilt_DfmActivity.java:35)
    at com.example.hilt_dfm.feature.DfmActivity.onCreate(DfmActivity.kt:17)
    at android.app.Activity.performCreate(Activity.java:7825)
    ...

Does Dagger Hilt currently support Dynamic Feature Modules? If not, is there a plan to support it?

There’s documentation on Hilt and DFM now at https://developer.android.com/training/dependency-injection/hilt-multi-module#dfm

In general though, because we’re built off of subcomponents and monolithic components you won’t be able to use the standard Hilt mechanisms like @AndroidEntryPoint with DFM.

Thank you. I’m really looking forward to it!
