能否以编程方式获取设备 运行 Android 6.0+ 的 MAC 地址?

Can one programmatically obtain the MAC address of a device running Android 6.0+?

能否以编程方式获取设备的 MAC 地址 运行 Android 6.0+?

根据this

To provide users with greater data protection, starting in this release, Android removes programmatic access to the device’s local hardware identifier for apps using the Wi-Fi and Bluetooth APIs. The WifiInfo.getMacAddress() and the BluetoothAdapter.getAddress() methods now return a constant value of 02:00:00:00:00:00.

这是否意味着在 Android 6.0+ 中无法获取设备的 MAC 地址?如果可能的话,你能告诉我如何在 Android Studio 中完成吗?

此外,this answer 仅适用于 Android 版本低于 6.0

的设备

您可以使用替代方法在 Android 6.0 设备上获取 MAC 地址。

首先将 Internet 用户权限添加到您的 AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

其次,

try {
        // get all the interfaces
        List<NetworkInterface> all = Collections.list(NetworkInterface.getNetworkInterfaces());
        //find network interface wlan0  
        for (NetworkInterface networkInterface : all) {
            if (!networkInterface.getName().equalsIgnoreCase("wlan0")) continue;
        //get the hardware address (MAC) of the interface    
            byte[] macBytes = networkInterface.getHardwareAddress();
            if (macBytes == null) {
                return "";
            }


            StringBuilder res1 = new StringBuilder();
            for (byte b : macBytes) {
                //gets the last byte of b
                res1.append(Integer.toHexString(b & 0xFF) + ":");
            }

            if (res1.length() > 0) {
                res1.deleteCharAt(res1.length() - 1);
            }
            return res1.toString();
        }
    } catch (Exception ex) {
           ex.printStackTrace();
    }
