如何在monodroid项目中使用.jar？

Question

我想在我的monodroid project.This SDK中使用百度地图Android SDK下载地址是http://developer.baidu.com/map/static/doc/BaiduMap_AndroidSDK_v2.1.0_All.zip

我按照Xamarin docs中描述的说明，创建了一个绑定项目，在文档中遵循了以下步骤，当构建绑定项目时，我得到了消息：

构建的操作成功，但出现了许多警告，并且某些类无法创建，JuHuiBao.Binding.dll无法正常工作。我如何解决这个问题？

您必须编辑Metadata.xml文件。到目前为止，设置绑定是非常困难的。新版本的mono for android应该会在java中公开一些方法，这可能会解决你的一些问题。我唯一能推荐的另一件事是遵循github上的Xamarin示例中提供的一些示例。他们有相当多的使用绑定的示例，可以帮助您了解如何编辑Metadata.xml文件。
