当wifi打开时，仅通过Android手机上的移动数据发送数据 [英] Send data only through mobile data on android phones when wifi is on

问题描述

是否可以通过移动数据以编程方式路由请求，即使 wifi 已打开并连接到互联网?

Is it possible to programmatically route a request through mobile data even when the wifi is on and connected to the internet?

我的应用需要调用运营商提供的服务，该服务只能通过移动数据使用，我认为要求关闭 wifi 对用户不友好.

My app needs to call a service provided by the operator which is only available through mobile data and I don't think it's user-friendly to ask for turning off the wifi.

you request a network, and then setDefaultNetwork( API before 23) or use bindProcessToNetwork for API >= 23 .
