我创建了一个绑定库项目，以便能够运行 Twilio 的 Android 可编程语音 SDK（v 2.0.5 -下载 .aar 文件的链接）。
我在Metadata.xml中添加了这行代码来修复一些错误：
<!-- solving: Error CS0102 The type 'ErrorEventArgs' already contains a definition for 'P0' TwilioBindings C:\...\TwilioBindings\obj\Debug\generated\src\Com.Twilio.Voice.IRegistrationListener.cs -->
<attr path="/api/package[@name='com.twilio.voice']/interface[@name='RegistrationListener']/method[@name='onError']" name="managedName">RegistrationListenerOnError</attr>
<attr path="/api/package[@name='com.twilio.voice']/interface[@name='UnregistrationListener']/method[@name='onError']" name="managedName">UnregistrationListenerOnError</attr>
<!-- Error CS0234 The type or namespace name 'InternalCall' does not exist in the namespace 'Com.Twilio.Voice' (are you missing an assembly reference?) TwilioBindings C:\...\TwilioBindings\obj\Debug\generated\src\Com.Twilio.Voice.Call.cs -->
<attr path="/api/package[@name='com.twilio.voice']/class[@name='InternalCall']" name="visibility">public</attr>
<!-- Error CS0115 'Call.OnWarning(IDictionary)': no suitable method found to override TwilioBindings C:\...\TwilioBindings\obj\Debug\generated\src\Com.Twilio.Voice.Call.cs -->
<attr path="/api/package[@name='com.twilio.voice']/class[@name='Call']/method[@name='onWarning' and count(parameter)=1 and parameter[1][@type='java.util.HashMap']]/parameter[1]" name="type">java.util.HashMap<java.lang.String, java.lang.Object></attr>
它编译成功，但是当我调用 Voice.Call() 时，该方法不返回任何内容，如果我在 ui 线程中调用它，ui 将永远卡住。我暂停了调试器，这样我就可以看到代码的哪一部分正在运行，它正在等待 Com.Twilio.Voice.Voice 中后续行的返回：
global::Com.Twilio.Voice.Call __ret = global::Java.Lang.Object.GetObject<global::Com.Twilio.Voice.Call> (JNIEnv.CallStaticObjectMethod (class_ref, id_call_Landroid_content_Context_Ljava_lang_String_Ljava_util_Map_Lcom_twilio_voice_Call_Listener_, __args), JniHandleOwnership.TransferLocalRef);
我的提示是，我在Metadata.xml中添加的某些行可能不正确，或者我需要添加更多。
我有一些警告可能有助于解决问题：

注意：因为 Twilio 的 Android 可编程语音 SDK 有一个依赖项（ReLinker 1.2.2（下载 .aar 文件的链接）），我不得不创建另一个绑定库项目（RelinkerBindings）来包含该依赖项，然后我在 Twilio 的绑定项目中引用了它。
我以前从未在 xamarin 中做过任何绑定项目，所以我对此有点陌生。
有谁知道如何解决这个问题？
提前致谢。
编辑：
我已经看到了 logcat 日志，这就是我调用 Voice.Call() 时发生的情况：
