但是在android中mac地址是直接寫在硬件中的,需要通過API 才能獲取
1、Android 獲取本機Mac 地址方法：
需要在AndroidManifest.xml文件中添加權限：
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
public String getLocalMacAddress() {
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo info = wifi.getConnectionInfo();
return info.getMacAddress();
}
2、Android 獲取本機IP地址方法：
public String getLocalIpAddress() {
try {
for (Enumeration<NetworkInterface> en = NetworkInterface
.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = en.nextElement();
for (Enumeration<InetAddress> enumIpAddr = intf
.getInetAddresses(); enumIpAddr.hasMoreElements();) {
InetAddress inetAddress = enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress()) {
return inetAddress.getHostAddress().toString();
}
}
}
} catch (SocketException ex) {
Log.e("WifiPreference IpAddress", ex.toString());
}
return null;
}
