我正在尝试编写一个在 android 上运行的简单 SIP 客户端，我下载了 SIPDemo 项目以便与它取得联系，然后我开始编写我的代码，但遇到了一些问题。
让我们向您展示代码：

好的，现在当我运行应用程序时，出现以下错误：

问题是我正在尝试为每个通过的注册步骤更新 TextView，我认为使用 runOnUiThread 可以，但我显然遗漏了一些东西。不用担心注册，它运行良好（它有点慢，但无论如何......）我可以在我的 SIP 服务器上看到该设备。
我的第二个问题是关于避免自动注册：我希望用户通过单击一个按钮来注册/注销自己到 SIP 服务器（如果你知道的话，就像在 zoiper 客户端中一样）我找不到任何例子，但如果你有一些我会很乐意阅读这些。如果您需要更多信息，请告诉我。
