Android判断网络是否已经连接

// check all network connect, WIFI or mobile
public static boolean isNetworkAvailable(final Context context) {

    NetworkInfo[] netInfos = cm.getAllNetworkInfo();
    for (NetworkInfo net : netInfos) {

        if (type.equalsIgnoreCase("WIFI")) {
            LevelLogUtils.getInstance().i(tag, "get Wifi connection");
            if (net.isConnected()) {

            }
        }
