我正在 android studio 中为 android Pie 编写一个应用程序。我想获取 wifi 信息。

    @RequiresApi(api = Build.VERSION_CODES.S)
    public String getData() {       
 
        String wifiDataTest;
        WifiInfo wifiInfo = wifiManager.getConnectionInfo();
        int frequency = wifiInfo.getFrequency();
        int ipAddress = wifiInfo.getIpAddress();
        int speed = wifiInfo.getLinkSpeed();
        String ssid = wifiInfo.getSSID();
        int wifiStandard = wifiInfo.getWifiStandard();

        wifiDataTest = "Frequency [MHz]: " + frequency + "\nIP address: " + ipAddress
                + "\nSpeed [Mbps]: " + speed + "\nSSID: " + ssid  + "\nWifi standard: " + wifiStandard;


        return "WIFI\n" + wifiDataTest;
    }

withint wifiStandard …
