我们正在定制的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 adb logcat 中的日志中发现，每次有DHCP更新时，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：
[ 11-24 10:10:11.751 2629: 3350 D/DhcpStateMachine ]
DHCP renewal on wlan0
[ 11-24 10:10:12.351 2629: 3350 D/DhcpStateMachine ]

在使用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？

我不认为
DISCONNECTING可以真正避免 . 处理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中的isConnectedOrConnecting方法而不是isConnected来验证我们是否已连接 .
