我正在尝试将 SightCall SDK 集成到我的 Xamarin Android 应用程序中。我创建了一个 Java 绑定库项目并创建了一个 Jars 文件夹并将 rtcc jar（Embedded Jar）放入其中，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。 so（嵌入式本机库）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 Binding Library 项目的 bin\Release 文件夹中的 dll 作为参考添加到我的项目中。我试图调用集成 SightCall 的方法，但我得到了一条Java.Lang.ExceptionInInitializerError线Rtcc.Initialize (appId, context); 这是我得到的例外：

如果我缺少任何步骤以及我需要如何解决此问题，请告诉我？
