I’m new to Hilt/Dagger. I have an existing project with a Singleton, and I need a parameter from the caller app stored in intent extras:

@Module
@InstallIn(SingletonComponent::class)
class MyModule
{
    @Provides
    @Singleton
    fun provideMyClass(
        @ApplicationContext appContext: Context,
        // @ActivityContext activityContext: Context
    ): MyClass{
        // Here I need a parameter I can normally retrieve from activity intent extras
        // val myParam = (activityContext as CompatActivity).intent.getStringExtra('foo')
    }
}

appContext works correctly, but AFAIK I can’t retrieve the extras from the Application, I need the Activity

Other classes:

@HiltAndroidApp
class MyApplication : Application()
{
    // ...
}

@AndroidEntryPoint
class MyActivity : ComponentActivity()
{
    @Inject
    lateinit var myClass: MyClass

    //...

    private fun myFunction() {
        doStuff(myClass)        
    }
}

If I try to replace @ApplicationContext appContext: Context with @ActivityContext activityContext: Context, I get the error

error: [Dagger/MissingBinding] @dagger.hilt.android.qualifiers.ActivityContext android.content.Context cannot be provided without an @Provides-annotated method.
public abstract static class SingletonC implements HiltWrapper_AuthenticationServiceConnectionEntryPoint,
^
Note: A binding for @dagger.hilt.android.qualifiers.ActivityContext android.content.Context exists in mypackage.MyApplication_HiltComponents.ActivityC:
@dagger.hilt.android.qualifiers.ActivityContext android.content.Context is injected at
[mypackage.MyApplication_HiltComponents.SingletonC] mypackage.MyModule.provideMyClass(�, activityContext, �)
mypackage.MyClass is injected at
[mypackage.MyApplication_HiltComponents.ActivityC] mypackage.MyActivity.myClass
mypackage.MyActivity is injected at
[mypackage.MyApplication_HiltComponents.ActivityC] mypackage.MyActivity_GeneratedInjector.injectMyActivity(mypackage.MyActivity) [mypackage.MyApplication_HiltComponents.SingletonC ? mypackage.MyApplication_HiltComponents.ActivityRetainedC ? mypackage.MyApplication_HiltComponents.ActivityC]
The following other entry points also depend on it:
dagger.hilt.android.internal.lifecycle.HiltViewModelFactory.ViewModelFactoriesEntryPoint.getHiltViewModelMap() [mypackage.MyApplication_HiltComponents.SingletonC ? mypackage.MyApplication_HiltComponents.ActivityRetainedC ? mypackage.MyApplication_HiltComponents.ViewModelC]

How can I get that parameter in there? The error seems to suggest I should put the @Provides somewhere, but I don’t know where (it doesn’t seem to work on the Activity)
