net.rtccloud.sdk.exception.RtccRuntimeException：无法在Xamarin中加载本机库

Question

我正在尝试将SightCall SDK集成到我的Xamarin Android应用中。我创建了一个Java Binding Library Project并创建了一个Jars文件夹，并在其中放置了rtcc jar（Embedded Jar），并在其中创建了一个libs文件夹和armeabi，armeabi-v7a和x86文件夹，每个文件夹都包含libRtcc-6.2.1。所以（Embedded Native Library）文件。我构建了这个项目并生成了dll。然后，我创建了一个Android应用程序，并将Java绑定库项目的bin \ Release文件夹中的dll添加为项目中的Reference。我尝试调用方法来集成SightCall，但我在Java.Lang.ExceptionInInitializerError行获得了Rtcc.Initialize (appId, context); 这是我得到的例外：

如果我错过了任何步骤以及我需要如何解决这个问题，请你告诉我吗？
