Question

我正在尝试将SightCall Android SDK集成到我的Xamarin应用中。由于SDK包含jar和.so文件，我需要将其绑定为Java绑定库，然后将其作为参考添加到我的项目中。我按照Xamarin网站中给出的创建Java Binding项目的步骤进行了操作，但在构建之后我遇到了12个错误和许多警告。 12个错误如下：

请您告诉我如何解决上述问题？

我已经注释了我尝试的各种方式，因为我收到警告，删除的节点路径没有匹配任何节点。

正如here所述，绑定应该遵循java包命名约定（小写）。

这里应该是：

net.rtccloud.sdk.event.meetingpoint.RequestEvent
而不是 Net.Rtccloud.Sdk.Event.Meetingpoint.RequestEvent

在Xamarin中绑定Java库时出现错误和警告？
