How can I set ProxySettings and ProxyProperties on Android Wi-Fi connection using Java?
Here's some code that should allow you to set/unset ProxyProperties. It uses some of the same code from the link above. The settings do not seem to take effect with the disconnect/reconnect.
public static Object getField(Object obj, String name)
throws SecurityException, NoSuchFieldException, IllegalArgumentException, IllegalAccessException{
Field f = obj.getClass().getField(name);
Object out = f.get(obj);
return out;
}
public static Object getDeclaredField(Object obj, String name)
throws SecurityException, NoSuchFieldException,
IllegalArgumentException, IllegalAccessException {
Field f = obj.getClass().getDeclaredField(name);
f.setAccessible(true);
Object out = f.get(obj);
return out;
}
public static void setEnumField(Object obj, String value, String name)
throws SecurityException, NoSuchFieldException, IllegalArgumentException, IllegalAccessException{
Field f = obj.getClass().getField(name);
f.set(obj, Enum.valueOf((Class<Enum>) f.getType(), value));
}
public static void setProxySettings(String assign , WifiConfiguration wifiConf)
throws SecurityException, IllegalArgumentException, NoSuchFieldException, IllegalAccessException{
setEnumField(wifiConf, assign, "proxySettings");
}
WifiConfiguration GetCurrentWifiConfiguration(WifiManager manager)
{
if (!manager.isWifiEnabled())
return null;
List<WifiConfiguration> configurationList = manager.getConfiguredNetworks();
WifiConfiguration configuration = null;
int cur = manager.getConnectionInfo().getNetworkId();
for (int i = 0; i < configurationList.size(); ++i)
{
WifiConfiguration wifiConfiguration = configurationList.get(i);
if (wifiConfiguration.networkId == cur)
configuration = wifiConfiguration;
}
return configuration;
}
void setWifiProxySettings()
{
//get the current wifi configuration
WifiManager manager = (WifiManager)getSystemService(Context.WIFI_SERVICE);
WifiConfiguration config = GetCurrentWifiConfiguration(manager);
if(null == config)
return;
try
{
//get the link properties from the wifi configuration
Object linkProperties = getField(config, "linkProperties");
if(null == linkProperties)
return;
//get the setHttpProxy method for LinkProperties
Class proxyPropertiesClass = Class.forName("android.net.ProxyProperties");

//pass the new object to setHttpProxy
Object[] params = new Object[1];

setHttpProxy.invoke(linkProperties, params);
setProxySettings("STATIC", config);
//save the settings
manager.updateNetwork(config);
manager.disconnect();
manager.reconnect();
}
catch(Exception e)
{
}
}
void unsetWifiProxySettings()
{
WifiManager manager = (WifiManager)getSystemService(Context.WIFI_SERVICE);
WifiConfiguration config = GetCurrentWifiConfiguration(manager);
if(null == config)
return;
try
{

Create a new WiFi connection with proxy
Well, rightly or wrongly this is how I am doing it (and it seems to work so far). To create a proxy setting, after I have created the Wifi connection I do:
Lang.JavaSystem.SetProperty("http.proxySet", "true");
Java.Lang.JavaSystem.SetProperty("http.proxyHost", _proxyName);
Java.Lang.JavaSystem.SetProperty("http.proxyPort", _proxyPort);
Java.Lang.JavaSystem.SetProperty("http.proxyUser", _proxyUsername);
Java.Lang.JavaSystem.SetProperty("http.proxyPassword", _proxyPassword);
And when I want to clear the proxy settings I do:
Java.Lang.JavaSystem.ClearProperty("http.proxySet");
Java.Lang.JavaSystem.ClearProperty("http.proxyHost");
Java.Lang.JavaSystem.ClearProperty("http.proxyPort");
Java.Lang.JavaSystem.ClearProperty("http.proxyUser");
Java.Lang.JavaSystem.ClearProperty("http.proxyPassword");
Wi-Fi + Proxy Configuration from Glassware
Ok, it seems to be impossible to do on the whole system, as the API that can do such thing requires a special permission and key.
So well, the proxy has to be managed per application.

How to set a static IP for new WiFi configuration?
After more than a year, I give up with setting a static IP (or DHCP, DNS, ...). Simply it's not possible, or, better, it's not allowed (from an arbitrary application).
Someone says:
"You could use NDK - this gives you low-level access to Linux under Android. Warning: don't expect this to be documented or supported. They might even ban you from Android Market (I know I would)"
For those who want to have some expriences with NDK, here is the a link:
http://developer.android.com/tools/sdk/ndk/index.html
Good luck, and give some feedback if you find something interesting!

Settings.Secure.HTTP_PROXY deprecated in ICS but no information on replacement
You can use Java Reflection to set the global proxy tested on ICS.
UPDATED CODE
Activity activity = this;
private void setProxtAndPortOnICS(String porxyServer2, int port2)
{
try
{
Class jwcjb = Class.forName("android.webkit.JWebCoreJavaBridge");
Class params[] = new Class[1];
params[0] = Class.forName("android.net.ProxyProperties");
Method updateProxyInstance = jwcjb.getDeclaredMethod("updateProxy", params);
Class wv = Class.forName("android.webkit.WebView");
Field mWebViewCoreField = wv.getDeclaredField("mWebViewCore");
Object mWebViewCoreFieldIntance = getFieldValueSafely(mWebViewCoreField, oauthPage);
Class wvc = Class.forName("android.webkit.WebViewCore");
Field mBrowserFrameField = wvc.getDeclaredField("mBrowserFrame");
Object mBrowserFrame = getFieldValueSafely(mBrowserFrameField, mWebViewCoreFieldIntance);
Class bf = Class.forName("android.webkit.BrowserFrame");
Field sJavaBridgeField = bf.getDeclaredField("sJavaBridge");
Object sJavaBridge = getFieldValueSafely(sJavaBridgeField, mBrowserFrame);
Class ppclass = Class.forName("android.net.ProxyProperties");
Class pparams[] = new Class[3];
pparams[0] = String.class;
pparams[1] = int.class;
pparams[2] = String.class;
Constructor ppcont = ppclass.getConstructor(pparams);
updateProxyInstance.invoke(sJavaBridge, ppcont.newInstance("my.proxy.com", 1234, null));
}
catch (Exception ex)
{
}
}
private Object getFieldValueSafely(Field field, Object classInstance) throws IllegalArgumentException, IllegalAccessException {
boolean oldAccessibleValue = field.isAccessible();
field.setAccessible(true);
Object result = field.get(classInstance);
field.setAccessible(oldAccessibleValue);
return result;
}
NOW you can filter out the urls using proxy server.
OR look at this blog this is in Chinese but you can read the code it is fairly easy to understand.
