在Xamarin中绑定没有源代码的Android库项目

Question

我一直在尝试这个很长一段时间。我必须尝试过数百种不同的方法来使其发挥作用，但尚未取得成功。让我来描述我想要做的事情。

我有一个由第三方组织提供的名为“androidservice”的Android库项目。由于它是一个源项目较近的项目，因此项目仅包含相关的.jar文件及其资源，如下面的项目层次结构所示。 （请注意，实际的.jar文件位于libs文件夹中。我假设bin文件夹中的文件没有用，因为它的大小非常小，只有166byte，我认为它是在项目得到时从空源生成的建）。

我想在Xamarin中使用这个“androidservice”库项目，我多次阅读http://developer.xamarin.com/guides/android/advanced_topics/java_integration_overview/binding_a_java_library_(.jar)/上的说明

我在Xamarin中创建了一个Android Java绑定库，并根据上面链接的文章的最后一部分添加了一个zip文件。绑定项目的结构如下所示。

其中thirdparty.zip包含“androidservice”项目的 bin 文件夹和 res 文件夹。

现在，因为bin文件夹中的原始androidservice.jar似乎不是正确的（仅166字节）并且使用此jar文件，绑定项目会出现错误“必须至少指定一个输入jar “在构建过程中，我用libs文件夹中的”androidservice.jar“替换了这个小jar，它有一个更大的845kb大小。 Jars文件夹中的jar文件都设置为“EmbeddedReferenceJar”。

然后我在我的Xamarin android项目中通过在引用中添加它来引用这个绑定库。

通过这个设置，绑定库和android项目都会构建。但是，在Android手机上以调试模式运行应用程序时，会显示错误消息：

[AndroidRuntime] java.lang.UnsatisfiedLinkError: Couldn't load opus from loader dalvik.system.PathClassLoader[dexPath=/data/app/com.company.myApp-1.apk,libraryPath=/data/app-lib/com.company.myApp-1]: findLibrary returned null

[AndroidRuntime]    at java.lang.System.loadLibrary(System.java:526)
[AndroidRuntime]    at com.thirdparty.eptt.android.service.RealVoice$3.run(RealVoice.java:194)

opus这个词似乎暗示它与libopus.so有关。

我查看了下面的所有链接，但都没有帮助。 http://forums.xamarin.com/discussion/8773/how-to-handle-so-libs-in-java-bindings-library

对可能的解决方案或进一步调试方法的任何建议都将不胜感激。
