Errors and warnings when Binding a Java Library in Xamarin?

Question

I am trying to integrate the SightCall Android SDK in my Xamarin app. Since the SDK contains a jar and .so file I need to bind it as a Java Binding Library as then add it as a Reference in my project. I followed the steps of creating a Java Binding project given in the Xamarin website but after building I'm getting 12 errors and many warnings. The 12 errors are below:

Could you please let me know how can I fix the above issues?

I have commented out the various ways in which I tried as I get a warning that the removed node path matched no nodes.

As described here, bindings should respect the java package naming convention (lowercased).

Here, it should be :

net.rtccloud.sdk.event.meetingpoint.RequestEvent
instead of
Net.Rtccloud.Sdk.Event.Meetingpoint.RequestEvent
