GameCircle - MonoDroid - Xamarin

Question

I'm trying to use GameCircle SDK on Xamarin Mono for android, but I have these problems:

Com.Amazon.Ags.Client.Whispersync.GameDataSingleMap.cs(23,23): Error CS0738: 
`Com.Amazon.Ags.Client.Whispersync.GameDataSingleMap' does not implement interface member 
`Com.Amazon.Ags.Client.Whispersync.Model.IMergeable.DeepCopy()' 
and the best implementing candidate 
`Com.Amazon.Ags.Client.Whispersync.GameDataSingleMap.DeepCopy()' 
return type `Com.Amazon.Ags.Client.Whispersync.GameDataSingleMap' 
does not match interface member return type `Java.Lang.Object' (CS0738) (GameCircle.MonoDroid)


Com.Amazon.Ags.Client.Whispersync.GameDataSingleMap.cs(23,23): Error CS0535: 
`Com.Amazon.Ags.Client.Whispersync.GameDataSingleMap' does not implement interface member 
`Com.Amazon.Ags.Client.Whispersync.Model.IMergeable.Merge(Java.Lang.Object)' (CS0535) (GameCircle.MonoDroid)

Com.Amazon.Ags.Client.Whispersync.Model.NumberList.cs(80,80): Error CS0103: The name `DeepCopy' does not exist in the current context (CS0103) (GameCircle.MonoDroid)

I've created a repository on GitHub so anyone can contribute to make it work.

Any help?

Thanks!!

This is due to limitations in the bindings generator and Java covariant return types. The fix is to add a managedReturn attribute to Transforms\Metadata.xml.

Please see the Problem: Class does not implement interface method section within the Binding a Java Library (.jar) documentation.

For example, you would add this XML fragment to Transforms\Metadata.xml:

<attr
    path="/api/package[@name='com.amazon.ags.client.whispersync']/class[@name='GameDataSingleMap']/method[@name='deepCopy']"
    name="managedReturn"
>Java.Lang.Object</attr>
