检查网络连接方式
ConnectivityManager manager = (ConnectivityManager) context.getSystemService
(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = manager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
if (networkInfo != null) {
return networkInfo.isConnected();
} ConnectivityManager manager = (ConnectivityManager) context.getSystemService
(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = manager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
APN模式, Wap连接下获取代理IP和端口号
private static final Uri PREFERRED_APN_URI = Uri.parse
