Dagger-reflect fails to inject classes with Android-dependent methods

[molokoka]

Dagger-reflect fails to inject objects with methods that have Android classes in their signature and that are not available in runtime.

For example:

class ExampleAndroidDependency @Inject constructor() {

    // is not used
    private fun getChannel(): NotificationChannel? { // dagger-reflect fails here
        return null
    }

//    @TargetApi(26) // fails too
//    private fun getChannel(): NotificationChannel? {
//        return null
//    }
}

I'm trying to inject this object in Android API 22.
getChannel() returns NotificationChannel object that is available from API 26.
Even if I would not use getChannel()method, dagger-reflect will fail to inject ExampleAndroidDependency

As a result of this issue we are not able to perform injections in some custom views.
For example:

• View1 injects some dependencies.
• View1 extends AppCompatTextView
• AppCompatTextView has method

@Override
@NonNull
@RequiresApi(api = 26)
public TextClassifier getTextClassifier()

• usage of View1 on Android API 22 fails. because dagger cannot find TextClassifier:
