如何在Android 5.0及更高版本中以编程方式设置wifi代理主机名，端口和绕过

Question

我想以编程方式设置 wifi 代理主机名、端口和旁路。 我点击此链接 ->如何使用 Java 在 Android Wi-Fi 连接上设置代理设置和代理属性？ 但该代码不适用于 Android 5.0.2。有没有其他方法可以设置这些设置？

测试。它在Android 5.1.0中工作，不要忘记添加权限

      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;
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    public void setWifiProxySettings5()
    {
        //get the current wifi configuration
        WifiManager manager = (WifiManager)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);
            //Method 1 to get the ENUM ProxySettings in IpConfiguration
            Class ipConfigClass = Class.forName("android.net.IpConfiguration");
            Field f = ipConfigClass.getField("proxySettings");
            Class proxySettingsClass = f.getType();
            //Method 2 to get the ENUM ProxySettings in IpConfiguration
            //Note the $ between the class and ENUM
            //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 pi = ProxyInfo.buildDirectProxy("127.0.0.1", 8118);
            //Android 5 supports a PAC file
            //ENUM value is "PAC"
            //ProxyInfo pacInfo = ProxyInfo.buildPacProxy(Uri.parse("http://localhost/pac"));
            //pass the new object to setHttpProxy
            Object[] params_SetHttpProxy = new Object[1];
            params_SetHttpProxy[0] = pi;
            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());
        }
    }
