How to change the extends in xamarin.android binding ?

Question

I want to binding a aar to android.

but there is an error:
ApkUpgradeInfo”不实现接口成员“IComparator.Compare(Object?, Object?)”

the code is :

public partial class ApkUpgradeInfo : global::Sdk.Service.Storekit.Bean.JsonBean, global::Java.IO.ISerializable, global::Java.Util.IComparator {

I want to remove the last global::Java.Util.IComparator{

how to remove it in metadata.xml?

Answer 1

class does not implement the interface member

This is a problem that occurs with binding Java methods with covariant return types. To fix the issue, try to add a partial class declaration for the 'ApkUpgradeInfo' class and explicitly implement IComparator.Compare method. Or remove the covariance from the generated C# code.
