https://github.com/google/dagger/issues/2752 anyone knows a workaround to provide a

FragmentActivity

for a qualifier of

@ActivityContext

using

@Binds

or it’s only possible to use the

@Provides

?

i’d expect a provides hiding the hard cast is the only way since it is a cast up and can’t be verified simply. though i’d guess you could validate it at compile time it would be expensive.

Ah I see, doing the hard cast was our current implementation 😞 something like this:

// TheModule.kt
// `as?` or using the pre-conditions by calling: Preconditions.checkNotNull(...)
@InstallIn(ActivityComponent::class)
@Module
object TheModule {

    @Provides fun fragmentActivity(@ActivityContext context: Context) = context as? FragmentActivity

}

// the injected class: MyClass.kt
class MyClass @Inject constructor(
    val fragmentActivity: FragmentActivity?
)

nullable, in case it failed with

ClassCastException
