我在 android 中使用 native sip 创建了 sip 应用程序。在其中我在从 sip 服务器注销帐户时遇到问题，每次我都收到 DATA_CONNECTION_LOST 。我也在 android 文档中看到，但是那里没有对此错误的简要解释。此外，它还面临着各种错误，而 regiterin 如 in_progress、transaction_terminated 等在 doc 中没有适当的解释。 这是我的代码:

最佳答案
我一直在检查 SipDemo 示例代码，我假设您将其用作您的应用程序的引用，也遇到了这个错误，但有注册过程。
在检查了 Android 的源代码 (4.1) 之后，我发现这是堆栈实现中的一个错误。更详细:
setRegistrationListener)时，由于网络信息尚未更新(未收到任何 Intent )，它会返回 SipErrorCode.DATA_CONNECTION_LOST，但实际上， session 最终已正确注册。 在您的情况下，当您在 unregister 方法中提供 SipRegistrationListener 时，此过程失败。一个丑陋的解决方法是等待一段时间以接收 Intent 或不提供监听器。
你还会看到，如果你用 setRegistrationLister 替换 unregister 调用，你仍然会收到同样的错误，所以你也可以尝试创建一个高层管理，这是，在 onRegistrationDone 回调中，您可以设置一个标志以了解您是否可以关闭配置文件。像这样的东西:
public void updateStatus(final int status, final Context context) {
if(status == STATUS_OK)
registered = true;
// Be a good citizen. Make sure UI changes fire on the UI thread.
this.runOnUiThread(new Runnable() {
public void run() {
generateNotification(context, statusToString(status));
}
});
}
并且，在关闭本地配置文件时:
public Boolean closeLocalProfile() {
Log.e("Closing profile", "closing profile " + me.getUriString());
if (manager == null || !registered) {
return false;
}
try {
if (me != null) {
Log.e("Unregistering profile", "Un registering profile ");
manager.unregister(me, null);
manager.close(me.getUriString());
}
} catch (Exception ee) {
Log.d("WalkieTalkieActivity/onDestroy", "Failed to close local profile.", ee);
}
return false;
}
请注意，我在 updateStatus 中使用了整数而不是字符串，并使用了辅助函数 statusToString 将状态代码转换为字符串。
正如您可能注意到的那样，这将添加一个额外的管理层，最初，它应该已经在堆栈中，但事实并非如此。我不太确定这是否会修复所有返回错误(在检查源代码后我看到了几个可能的错误)，但应该有所帮助。
