Wrong return type: androidx/media3/common/SimpleBasePlayer$State$Builder.Build()

[markusroessler]

Android framework version

net8.0-android

Affected platform version

.NET 8.0.403 / Xamarin.AndroidX.Media3.Common 1.4.1

Description

The method androidx/media3/common/SimpleBasePlayer$State$Builder.Build() currently returns Java.Lang.Object instead of androidx/media3/common/SimpleBasePlayer$State. This leads to a NoSuchMethodException at runtime. See Android docs: https://developer.android.com/reference/androidx/media3/common/SimpleBasePlayer.State.Builder#build()

Steps to Reproduce

Just invoke the method androidx/media3/common/SimpleBasePlayer$State$Builder.Build()

Did you find any workaround?

yes:

private unsafe State? Build(SimpleBasePlayer.State.Builder builder)
       {
           var objRef = builder.JniPeerMembers.InstanceMethods.InvokeAbstractObjectMethod("build.()Landroidx/media3/common/SimpleBasePlayer$State;", builder, null);
           return GetObject<State>(objRef.Handle, JniHandleOwnership.TransferLocalRef);
       }
