I'm trying to import PAC file from URL and change Wifi proxy settings programmatically. I searched and found that it`s possible with:

ProxyInfo.buildPacProxy(Uri.parse("someurl")

Before asking this question I checked here and also all of this. The problem that I face is when I implement some of these solutions everything compiles well without exceptions, but when I check there are no proxy settings updated.
This is my last code, but once again without success:

public void setWifiProxySettings5()

 //get the current wifi configuration
 WifiManager manager = (WifiManager)getApplicationContext().getSystemService(Context.WIFI_SERVICE);
 WifiConfiguration config = GetCurrentWifiConfiguration(manager);
 if(null == config)
 return;

 try
 
 //linkProperties is no longer in WifiConfiguration
 Class proxyInfoClass = Class.forName("android.net.ProxyInfo");
 Class[] setHttpProxyParams = new Class[1];
 setHttpProxyParams[0] = proxyInfoClass;
 Class wifiConfigClass = Class.forName("android.net.wifi.WifiConfiguration");
 Method setHttpProxy = wifiConfigClass.getDeclaredMethod("setHttpProxy", setHttpProxyParams);
 setHttpProxy.setAccessible(true);

 Class proxySettingsClass = Class.forName("android.net.IpConfiguration$ProxySettings");

 Class[] setProxySettingsParams = new Class[1];
 setProxySettingsParams[0] = proxySettingsClass;
 Method setProxySettings = wifiConfigClass.getDeclaredMethod("setProxySettings", setProxySettingsParams);
 setProxySettings.setAccessible(true);


 ProxyInfo pacInfo = ProxyInfo.buildPacProxy(Uri.parse("http://localhost/pac"));

 //pass the new object to setHttpProxy
 Object[] params_SetHttpProxy = new Object[1];
 params_SetHttpProxy[0] = pacInfo;
 setHttpProxy.invoke(config, params_SetHttpProxy);

 //pass the enum to setProxySettings
 Object[] params_setProxySettings = new Object[1];
 params_setProxySettings[0] = Enum.valueOf((Class<Enum>) proxySettingsClass, "STATIC");
 setProxySettings.invoke(config, params_setProxySettings);

 //save the settings
 manager.updateNetwork(config);
 manager.disconnect();
 manager.reconnect();
 
 catch(Exception e)
 
 Log.v("wifiProxy", e.toString());
