android WIFI 设置代理代码 4.4.3——5.0

Posted 2020-10-07

记录下android中设置代理代码 或许有朋友能用的上

适用于4.4.3 在5.0上android.net.ProxyProperties 找不到 估计API被谷歌拿掉了 4.4.4还没试估计API还在

private static String NOTPROXY = ""; //不走代理名单

     private  static   List<String> list;
    //type为1设置wifi设置   为0是清除代理
    public static void setWifi(Context context, final String ip, final int port, final int type) throws SecurityException, IllegalArgumentException,
            NoSuchFieldException, IllegalAccessException,
            NoSuchMethodException, ClassNotFoundException,
