改变无线先进的从code选项，但它不会工作？ [英] changed wifi advanced option from code but it won't work?
问题描述
我用这个code键更改无线IP设置（IP地址和网关）
您可以看到完整的code在这里：<一href="http://stackoverflow.com/questions/25141229/change-internet-proxy-wifi-3g-gprs-in-android-2-2-an-upper-from-$c$c">full类
WifiConfiguration wifiConf = NULL;
WifiManager经理=（WifiManager）getSystemService（MainActivity.WIFI_SERVICE）;
WifiInfo connectionInfo = manager.getConnectionInfo（）;
名单＆LT; WifiConfiguration＆GT; configuredNetworks =经理
.getConfiguredNetworks（）;
wifiConf = GetCurrentWifiConfiguration（经理）;
setIpAssignment（静态，wifiConf）;
setIpAddress（InetAddress.getByName（192.2.2.2），24，wifiConf）;
setGateway（InetAddress.getByName（192.2.2.22），wifiConf）;
manager.updateNetwork（wifiConf）;
manager.saveConfiguration（）;
功能：
公共静态无效setIpAssignment（字符串赋值，WifiConfiguration wifiConf）
抛出SecurityException异常，抛出：IllegalArgumentException，NoSuchFieldException，IllegalAccessException {
setEnumField（wifiConf，分配，ipAssignment）;
}
公共静态无效setIpAddress（InetAddress类地址，诠释prefixLength，WifiConfiguration wifiConf）
抛出SecurityException异常，抛出：IllegalArgumentException，NoSuchFieldException，IllegalAccessException，
NoSuchMethodException，ClassNotFoundException异常，InstantiationException，的InvocationTargetException {
对象linkProperties = getfield命令（wifiConflinkProperties）;
如果（linkProperties == NULL）回报;
类laClass =的Class.forName（android.net.LinkAddress）;
构造laConstructor = laClass.getConstructor（新类[] {InetAddress.class，int.class}）;
对象linkAddress上= laConstructor.newInstance（地址，prefixLength）;
ArrayList的mLinkAddresses =（ArrayList中）getDeclaredField（linkProperties，mLinkAddresses）;
mLinkAddresses.clear（）;
mLinkAddresses.add（linkAddress上）;
}
公共静态无效setGateway（InetAddress类网关，WifiConfiguration wifiConf）
抛出SecurityException异常，抛出：IllegalArgumentException，NoSuchFieldException，IllegalAccessException，
ClassNotFoundException的，NoSuchMethodException，InstantiationException，的InvocationTargetException {
对象linkProperties = getfield命令（wifiConflinkProperties）;
如果（linkProperties == NULL）回报;
类routeInfoClass =的Class.forName（android.net.RouteInfo）;
构造routeInfoConstructor = routeInfoClass.getConstructor（新等级[] {InetAddress.class}）;
对象routeInfo = routeInfoConstructor.newInstance（网关）;
ArrayList的mRoutes =（ArrayList中）getDeclaredField（linkProperties，mRoutes）;
mRoutes.clear（）;
mRoutes.add（routeInfo）;
}
问题是在这里：
这些codeS成功改变IP地址和网关，当你从你的android设备设置检查WiFi连接先进的选项，但实际上设置未设置！
我是如何理解这一点：
首先，我手动设置一个假的IP地址和网关，修改网络 - >高级选项。然后尝试打开一个网站，Chrome浏览器，没有互联网连接和它的工作。然后，我设置了相同的IP地址和网关从code连接的SSID，但它没有工作，仍然有互联网连接。
我使用code相同的设置和手动，但它不是从code的工作。在这里我做错了？
mWifiManager.updateNetwork（selectWIfiConfi）;
mWifiManager.saveConfiguration（）;
mWifiManager.setWifiEnabled（假）;
mWifiManager.setWifiEnabled（真正的）;
我重新打开无线网络，并将其作品phone`s 4.2.2版本
I used this code to change wifi Ip setting (Ip Address and gateway)
you can see the full code here : full class
WifiConfiguration wifiConf = null;
WifiManager manager = (WifiManager) getSystemService(MainActivity.WIFI_SERVICE);
WifiInfo connectionInfo = manager.getConnectionInfo();
List<WifiConfiguration> configuredNetworks = manager
.getConfiguredNetworks();
wifiConf = GetCurrentWifiConfiguration(manager);
setIpAssignment("STATIC", wifiConf);
setIpAddress(InetAddress.getByName("192.2.2.2"), 24, wifiConf);
setGateway(InetAddress.getByName("192.2.2.22"), wifiConf);
manager.updateNetwork(wifiConf);
manager.saveConfiguration();
functions:
public static void setIpAssignment(String assign , WifiConfiguration wifiConf)
throws SecurityException, IllegalArgumentException, NoSuchFieldException, IllegalAccessException{
setEnumField(wifiConf, assign, "ipAssignment");
}
public static void setIpAddress(InetAddress addr, int prefixLength, WifiConfiguration wifiConf)
throws SecurityException, IllegalArgumentException, NoSuchFieldException, IllegalAccessException,
NoSuchMethodException, ClassNotFoundException, InstantiationException, InvocationTargetException{
Object linkProperties = getField(wifiConf, "linkProperties");
if(linkProperties == null)return;
Class laClass = Class.forName("android.net.LinkAddress");
Constructor laConstructor = laClass.getConstructor(new Class[]{InetAddress.class, int.class});
Object linkAddress = laConstructor.newInstance(addr, prefixLength);
ArrayList mLinkAddresses = (ArrayList)getDeclaredField(linkProperties, "mLinkAddresses");
mLinkAddresses.clear();
mLinkAddresses.add(linkAddress);
}
public static void setGateway(InetAddress gateway, WifiConfiguration wifiConf)
throws SecurityException, IllegalArgumentException, NoSuchFieldException, IllegalAccessException,
ClassNotFoundException, NoSuchMethodException, InstantiationException, InvocationTargetException {
Object linkProperties = getField(wifiConf, "linkProperties");
if(linkProperties == null)return;
Class routeInfoClass = Class.forName("android.net.RouteInfo");
Constructor routeInfoConstructor = routeInfoClass.getConstructor(new Class[]{InetAddress.class});
Object routeInfo = routeInfoConstructor.newInstance(gateway);
ArrayList mRoutes = (ArrayList)getDeclaredField(linkProperties, "mRoutes");
mRoutes.clear();
mRoutes.add(routeInfo);
}
problem is here :
these codes successfully change the ip address and gateway when you check wifi connection advanced option from setting in your android device, but the setting actually isn't set!!!
how I understand this :
first I set a fake Ip address and gateway manually, modify network-> advanced option. and then try to open a website with chrome, no internet access and it worked. then I set the same Ip address and gateway for connected ssid from code but It's not worked and still have internet access.
I used same settings from code and manually but its not worked from code. where I did wrong ?
mWifiManager.updateNetwork(selectWIfiConfi);
mWifiManager.saveConfiguration();
mWifiManager.setWifiEnabled(false);
mWifiManager.setWifiEnabled(true);
I reopen wifi and it works phone`s version 4.2.2
