Android手机获取手机获取Mac地址的几种方法地址的几种方法
今天小编就为大家分享一篇关于Android手机获取Mac地址的几种方法,小编觉得内容挺不错的,现在分享给大
家,具有很好的参考价值,需要的朋友一起跟随小编来看看吧
最常用的方法,通过WiFiManager获取:
/**
* 通过WiFiManager获取mac地址
* @param context
* @return
*/
private static String tryGetWifiMac(Context context) {
WifiManager wm = (WifiManager) context.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
WifiInfo wi = wm.getConnectionInfo();
if (wi == null || wi.getMacAddress() == null) {
return null;
}
if ("02:00:00:00:00:00".equals(wi.getMacAddress().trim())) {
return null;
} else {
return wi.getMacAddress().trim();
}
}
这个方法Android 7.0是获取不到的,返回的是null,其实是返回“02:00:00:00:00:00”
根据本地IP获取:
/**
* 根据IP地址获取MAC地址
* @return
*/
private static String getLocalMacAddressFromIp() {
String strMacAddr = null;
try {
//获得IpD地址
InetAddress ip = getLocalInetAddress();
byte[] b = NetworkInterface.getByInetAddress(ip).getHardwareAddress();
StringBuffer buffer = new StringBuffer();
for (int i = 0; i < b.length; i++) {
if (i != 0) {
buffer.append(':');
}
String str = Integer.toHexString(b[i] & 0xFF);
buffer.append(str.length() == 1 ? 0 + str : str);
}
strMacAddr = buffer.toString().toUpperCase();
} catch (Exception e) {
}
return strMacAddr;
}
/**
* 获取移动设备本地IP
* @return
*/
private static InetAddress getLocalInetAddress() {
InetAddress ip = null;
try {
//列举
Enumeration<NetworkInterface> en_netInterface = NetworkInterface.getNetworkInterfaces();
while (en_netInterface.hasMoreElements()) {//是否还有元素
NetworkInterface ni = (NetworkInterface) en_netInterface.nextElement();//得到下一个元素
Enumeration<InetAddress> en_ip = ni.getInetAddresses();//得到一个ip地址的列举
while (en_ip.hasMoreElements()) {
ip = en_ip.nextElement();
if (!ip.isLoopbackAddress() && ip.getHostAddress().indexOf(":") == -1)
break;
else
ip = null;
}
if (ip != null) {
break;
}
}
} catch (SocketException e) {
e.printStackTrace();
}
