android - 带有 java.lang.reflect.InvocationTargetException 的 android 上的 JAIN SIP

Question

我是一名新的 android 开发人员，目前我正在尝试在 andorid 中实现 JSIP。当我在andorid中添加jsip api时，一个错误告诉我jsip的javax包与java的默认javax包冲突。

所以我把所有的javax包都改成了com.g5.javax.*这种格式。然后错误消失了。但现在出现了另一个错误，我将其附加到此消息中。它抛出 java.lang.reflect.InvocationTargetException 和 javax.sip.PeerUnavailableException: stack name is missing 错误。我检查并仔细检查了 jain sip 源，发现属性键“com.g5.javax.sip.STACK_NAME”(通过使用 eclipse 重构更改)具有我给出的值。但每次都会出现错误。另一个有趣的信息是我创建的同一个 jar 包在桌面应用程序中完美运行。我已经坚持这个错误 2 天了。

我也遇到了同样的问题，所以我尝试更深入地挖掘，因为没有报告堆栈实现的错误。从这里我得到了这个错误:

现在问题来了。我查看了 SipStackImpl 类的代码并找到了这些行:

String name = configurationProperties
    .getProperty("com.tlccom.javax.sip.STACK_NAME");
if (name == null) 
    throw new PeerUnavailableException("stack name is missing");

所以这意味着该名称未被提取。所以我给了这个名字一个字符串值，但仍然有错误，这让我相信 SipStackImpl 是从其他地方获取的。问题是我不知道在哪里，我已经在整个项目中搜索了那个错误，那是它唯一存在的地方，所以它一定来自某个地方(即使注释掉错误检测仍然会留下错误)。这就是我现在卡住的地方，希望这对您有所帮助，如果您发现任何额外的信息，请告诉我
