Question

我们正在定制Android平台上开发软件，我们开始收到客户关于Wifi连接状态的投诉。似乎有一段时间，他们松开了他们的Wifi连接1-2秒，然后它自动返回。他们可以从一个小的GUI反馈或从XMPP客户端发出的断开/重新连接事件中注意到这一点。

经过调查，我们从登录adb logcat中发现，每次有DHCP续订时，Wifi都会将其状态从CONNECTED更改为CONNECTING。由于我们目前的DHCP租用时间为1小时，我们的平台每隔29分钟尝试更新一次地址。以下是DHCP续订的日志摘录：

使用DHCP时，如何防止连接状态从CONNECTED更改为CONNECTING？我可以在某处更改设置以更改此行为吗？

Answer 1

我认为DISCONNECTING不能真正避免。解决此问题的唯一方法是忽略Wifi更改状态下的DISCONNECTING状态，并使用Network而不是isConnectedOrConnecting中的isConnected方法验证我们是否是否连接。
