之前寫了【Android】獲取Mac地址【1】有些不夠詳細，現在貼上一些其他代碼，僅供參考。
（1） 調用android 的API： NetworkInterface. getHardwareAddress ()
該API的level為9，只有android 2.3以上才有該接口
geMacFromInetAddress /** * 通過InetAddress獲取mac地址 * @attention InetAddress * @return Mac Address */
private static String geMacFromInetAddress(Context context){
String mResult = null;
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() && InetAddressUtils.isIPv4Address(inetAddress.getHostAddress())) {
Log.i(TAG_NETWORK,"get the ip address(inetAddress): "+inetAddress.getHostAddress().toString());
byte[] b = NetworkInterface.getByInetAddress(inetAddress).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);
}
mResult = buffer.toString().toUpperCase();
Log.i(TAG_NETWORK,"MAC address geMacFromInetAddress: "+mResult);
return mResult;
}
}
}
} catch (SocketException ex) {
Log.i(TAG_NETWORK,ex.toString());
}
return null;
}
AndroidManifest.xml <uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="9" />
（2） 調用java 的方法： nbtstat/arp
一般android不支持這兩個命令。該方法沒有試過。
（3） 調用Android的API： WifiManager
權限：
AndroidManifest.xml<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
代碼：
getMacFromWifi /** * 通過wifiManager獲取mac地址 * @attention Wifi * @return Mac Address */
private static String getMacFromWifi(Context context){
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
if (!wifiManager.isWifiEnabled()) {
wifiManager.setWifiEnabled(true);
}
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
String mResult = wifiInfo.getMacAddress();
Log.i(TAG_NETWORK,"Mac address(wifi): "+mResult);
return mResult;
}
這個是需要設備開通Wifi連接，獲取到網卡的MAC地址
另，貼上，判斷當前是否為wifi連接方式：
isWifiConnected //判斷當前是否使用wifi連接
private static boolean isWifiConnected(Context context){
ConnectivityManager cm;
cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
boolean result = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState() == NetworkInfo.State.CONNECTED ? true : false ;
Log.i(TAG_NETWORK,"isWifiConnected: "+result);
return result;
}
（4） 調用Linux的busybox
getMacFromCallCmd /** * 通過callCmd("busybox ifconfig","HWaddr")獲取mac地址 * @attention 需要設備裝有busybox工具 * @return Mac Address */
private static String getMacFromCallCmd(){
String result = "";
result = callCmd("busybox ifconfig","HWaddr");
if(result == null || result.length() <= 0){
Log.i(TAG_NETWORK,"callCmd returns null or empty");
return null;
}
//對該行數據進行解析
//例如：eth0 Link encap:Ethernet HWaddr 00:16:E8:3E:DF:67
if(result.length()>0 && result.contains("HWaddr")==true){
String Mac = result.substring(result.indexOf("HWaddr")+6, result.length()-1);
Log.i(TAG_NETWORK,"Mac:"+Mac+" Mac.length: "+Mac.length());
if(Mac.length()>1){
Mac = Mac.replaceAll(" ", "");
result = "";
String[] tmp = Mac.split(":");
for(int i = 0;i<tmp.length;++i){
result +=tmp[i];
}
}
Log.i(TAG_NETWORK,result+" result.length: "+result.length());
}
Log.i(TAG_NETWORK,"Mac address(CallCmd): "+result);
return result;
}
其他相關函數：
callCmd public static String callCmd(String cmd,String filter) {
String result = "";
String line = "";
try {
Process proc = Runtime.getRuntime().exec(cmd);
InputStreamReader is = new InputStreamReader(proc.getInputStream());
BufferedReader br = new BufferedReader (is);
//執行命令cmd，只取結果中含有filter的這一行
while ((line = br.readLine ()) != null && line.contains(filter)== false) {
//result += line;
Log.i("test","line: "+line);
}
result = line;
Log.i("test","result: "+result);
}
catch(Exception e) {
e.printStackTrace();
}
return result;
}
這個需要設備支持busybox工具。現在發現一些設備是沒有安裝該工具的，這時使用該方法，會報錯。
（5）查詢記錄了MAC地址的文件“/proc/net/arp”
需要有這個文件，並且記錄了相應的內容
getMacFromFile /** * get the Mac Address from the file /proc/net/arp * @param context * @attention the file /proc/net/arp need exit * @return Mac Address */
private static String getMacFromFile(Context context){
String mIP = Config.getIpAddress(context);
if(mIP == null || mIP.length()<=0)
return null;
List<String> mResult = readFileLines("/proc/net/arp");
Log.d(TAG_NETWORK,"======= /proc/net/arp =========");
for(int i =0;i<mResult.size();++i)
Log.d("line",mResult.get(i));
Log.d(TAG_NETWORK,"===========================");
if(mResult !=null && mResult.size()>1){
for(int j =1;j<mResult.size();++j){
List<String> mList = new ArrayList<String>();
String[] mType = mResult.get(j).split(" ");
for(int i =0;i<mType.length;++i){
if(mType[i]!=null && mType[i].length()>0)
mList.add(mType[i]);
}
if(mList!=null && mList.size()>4 && mList.get(0).equalsIgnoreCase(mIP)){
String result="";
String[] tmp = mList.get(3).split(":");
for(int i = 0;i<tmp.length;++i){
result +=tmp[i];
}
result = result.toUpperCase();
Log.i(TAG_NETWORK,"Mac address(file): "+result);
return result;
}
}
}
return null;
}
readFileLines /** * 以行為單位讀取文件，常用於讀面向行的格式化文件 */
private static List<String> readFileLines(String fileName) {
File file = new File(fileName);
BufferedReader reader = null;
String tempString ="";
List<String> mResult = new ArrayList<String>();
try {
Log.i("result","以行為單位讀取文件內容，一次讀一整行：");
reader = new BufferedReader(new FileReader(file));
while((tempString = reader.readLine())!=null){
mResult.add(tempString);
}
reader.close();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (reader != null) {
try {
reader.close();
} catch (IOException e1) {
}
}
}
return mResult;
}
記錄了MAC地址的文件“/proc/net/arp”內容大致如下：
IP address HW type Flags HW address Mask Device
10.63.253.193 0x1 0x2 00:11:92:06:85:3f * eth0
10.63.253.194 0x1 0x2 00:11:92:06:85:3a * eth1
10.63.253.195 0x1 0x2 00:11:92:06:85:3b * eth2
Done！！睡覺嘍~
