Answer 1

试试这个：

public static boolean isVPNConnected() {
    List<String> networkList = new ArrayList<>();
    try {
        for (NetworkInterface networkInterface : Collections.list(NetworkInterface.getNetworkInterfaces())) {
            if (networkInterface.isUp()) {networkList.add(networkInterface.getName());}
        }
    } catch (Exception ex) {
        Logger.dbg("isVPNConnected Network List exception");
    }
    return networkList.contains("tun0") || networkList.contains("ppp0");
}
