我在使用OsmDroid在地图中集成一些标记时遇到了一些麻烦。事实上，我甚至不在我的App Project中。 我是先锋：绑定项目。 我需要实现一些不在v3.4中的osmbonuspack_v5.1的函数。
我调整了Metadata.xml以使用这些新的jar（我使用的是osmdroid v4.3 / osmbonuspack v5.1和slf4j v1.6.1），但仍有2个错误让我发疯。
如何使用osmbonuspack_v5.1实现这两个类（ CleaningTask ＆amp; DownloadingTask ）？
以下是详细信息：

这是我的Metadata.xml：

这里是错误的参考：

return JNIEnv.FindClass ("org/osmdroid/bonuspack/cachemanager/CacheManager$CleaningTask", ref java_class_handle);

和
// Metadata.xml XPath class reference: path="/api/package[@name='org.osmdroid.bonuspack.cachemanager']/class[@name='CacheManager.DownloadingTask']"

}
我已经按照http://developer.xamarin.com/guides/android/advanced_topics/java_integration_overview/binding_a_java_library_%28.jar%29/上的教程，但我不明白如何处理我的Java.Lang.Object。
提前感谢，我认为这很简单，但我肯定没有得到它。
