&引用；格式错误的请求”；在Twilio Android客户端中进行呼叫时出错

我正在尝试将Twilio客户端集成到一个更大的应用程序中。在我调用

device.connect（参数，connectionListener）

之前，一切似乎都正常。我得到了

31100通用格式错误请求

错误，就是这样

在同一台设备上，使用相同的Twilio帐户和相同的Twilio应用程序，Twilio Android SDK（MonkeyPhone）提供的示例代码可以完美地工作

我找不到更多关于错误含义或可能原因的详细信息。虽然我假设我发送的是无效数据，但我不知道这怎么可能。功能令牌是正常的，我已经对照MonkeyPhone示例应用程序中生成的令牌进行了验证。创建

设备

工作正常，没有错误。即使在

connect（）

方法中没有发送任何参数，也会引发错误。调用了

ConnectionListener

的

onConnecting（）

方法，但随后调用了

onDisconnected（Connection-inConnection，int-inErrorCode，String-inErrorMessage）

，请求格式错误

Voice TwiML的代码运行良好，它只是一个简单的PHP脚本，生成了最简单的

动词：

<Response>
    <Dial>someone</Dial>
</Response>

多谢各位

我解决了这个问题。显然，我必须使用UTF-8编码从服务器读取InputStream（即使令牌中没有特殊字符）

您是否在后台服务中为来电实现了twilio代码？对不起，已经很久了，我不记得了。
