安卓：强制要发送的数据通过无线电VS无线网络 [英] Android: Force data to be sent over radio vs WiFi

问题描述

是否有可能迫使一个Android应用程序只使用移动无线连接（3G / 4G /等），禁止使用的WiFi？

Is it possible to force an Android application to use only the mobile radio connection (3g/4g/etc), disallowing the use of WiFi?

我想，我想用一个HIPRI连接：（例如：WIFI打开，使用HIPRI 3G）： 的http://groups.google.com/group/android-developers/browse_thread/thread/d41f85505484d29b

I think I want to use a HIPRI connection: (ex: WIFI turned on, use HIPRI 3G): http://groups.google.com/group/android-developers/browse_thread/thread/d41f85505484d29b

推荐答案

我不相信你可以逼没有明确关闭Wi-Fi无线电暂时连接路径（不推荐）。但是，你可以尝试在你希望这种情况发生期间设置网络preference：

I don't believe you can "force" the connection path without explicitly turning off the Wi-Fi radio temporarily (not recommended). However, you could try setting the network preference during the period you want this to occur:

ConnectivityManager cm = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
//Prefer mobile over wifi
cm.setNetworkPreference(ConnectivityManager.TYPE_MOBILE);

//Do your work

//Remove your preference
cm.setNetworkPreference(ConnectivityManager.DEFAULT_NETWORK_PREFERENCE);
