android怎么获取mac地址

在Android中获取MAC地址可以通过以下几种方法：

使用WifiManager获取MAC地址：

WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);String macAddress = wifiManager.getConnectionInfo().getMacAddress();

使用NetworkInterface获取MAC地址：

try {List<NetworkInterface> interfaces = Collections.list(NetworkInterface.getNetworkInterfaces());for (NetworkInterface intf : interfaces) {if (intf.getName().equalsIgnoreCase("wlan0")) {byte[] mac = intf.getHardwareAddress();if (mac == null) {macAddress = "";} else {StringBuilder buf = new StringBuilder();for (byte aMac : mac) {buf.append(String.format("%02X:", aMac));}if (buf.length() > 0) {buf.deleteCharAt(buf.length() - 1);}macAddress = buf.toString();}break;}}} catch (SocketException e) {e.printStackTrace();}

请注意，获取MAC地址可能需要权限，如ACCESS_WIFI_STATE和INTERNET。另外，Android 6.0及以上版本需要动态请求权限。
