在 Xamarin Android 绑定库中使用 Twilio 可编程语音的问题
Problems using Twilio Programmable Voice in a Xamarin Android Bindings Library
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 - link to download .aar file）。
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() 时该方法没有 return 任何东西，如果我在 ui 线程中调用它 ui 保持永远卡住了。我暂停了调试器，所以我可以看到代码的哪一部分是 运行ning 并且它正在等待 Com.Twilio.Voice.Voice:
中后续行的 return
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。
我收到了一些可能有助于解决问题的警告：

注意： 因为 Twilio 的 Android 可编程语音 SDK 具有依赖项（ReLinker 1.2.2 (link to download .aar file)），我不得不创建另一个绑定库项目 (RelinkerBindings) 以包含该依赖项，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。

我添加了对 RelinkerBindings 项目的引用，该项目包含 Twilio 项目的依赖项，但不知何故，日志显示未找到 RelinkerBindings，因此我删除了对该项目的引用并添加了对Relinker dll 文件，现在可以使用了。
不知道为什么它在引用项目时不起作用。
