[Media3] Cant implement interface Transformer.IListener

[Colinkl]

Android framework version

net9.0-android

Affected platform version

Xamarin.AndroidX.Media3.Transformer 1.8.0

Description

In package 'Xamarin.AndroidX.Media3.Transformer' v1.8.0
Interface Transformer.IListener does not declare any members.
I cannot override or implement 'OnCompleted' 'OnError' 'OnFallbackApplied'

Steps to Reproduce

1 Create new class TransformerListener : Java.Lang.Object, Transformer.IListener
2. Try to implement any member

Did you find any workaround?

No

I can see these APIs here:

android-libraries/source/androidx.media3/media3-transformer/PublicAPI/PublicAPI.Unshipped.txt

Lines 568 to 571 in c12c66a

	AndroidX.Media3.Transformer.Transformer.IListener
	AndroidX.Media3.Transformer.Transformer.IListener.OnCompleted(AndroidX.Media3.Transformer.Composition? composition, AndroidX.Media3.Transformer.ExportResult? exportResult) -> void
	AndroidX.Media3.Transformer.Transformer.IListener.OnError(AndroidX.Media3.Transformer.Composition? composition, AndroidX.Media3.Transformer.ExportResult? exportResult, AndroidX.Media3.Transformer.ExportException? exportException) -> void
	AndroidX.Media3.Transformer.Transformer.IListener.OnFallbackApplied(AndroidX.Media3.Transformer.Composition? composition, AndroidX.Media3.Transformer.TransformationRequest? originalTransformationRequest, AndroidX.Media3.Transformer.TransformationRequest? fallbackTransformationRequest) -> void

Is this the one you are looking for?

API looks OK.
