WIFI和移动数据同时打开， OS 检测到WIFI 无 Internet， 默认走了 移动网络 手机连接 设备的AP， 通过局域网方式把 路由器的账号密码发过去。错误日志如下：

提示错误为: java.net.SocketTimeoutException: failed to connect to /192.168.169.1 (port 80) from /10.110.27.199 (port 47326) after 6000ms
-- 192.168.169.1 是设备固定IP， 10.11.27.199应该为手机IP， 连接超时。
发送的时候WIFI并没有断开，但错误日志中打印的IP却为10.11.27.199。于是我在发送的时候又在代码中打印了一下IP为正常的(192.168.169.2)。 于是我开启飞行模式关闭了移动数据， 只连设备Ap，再次请求。 请求成功。 测试手机为 HUAWEI BLA-AL00 Android系统版本号：9 有没有方法 不手动关闭 移动网络 ，仍然请求成功呢。
