【Android】擷取Mac地址【2】

之前寫了【Android】擷取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以上才有該介面

（2） 調用java 的方法： nbtstat/arp

 

一般android不支援這兩個命令。該方法沒有試過。

（3） 調用Android的API： WifiManager

許可權：

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

代碼：

/** * 通過wifiManager擷取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;}

這個是需要裝置開通Wifi串連，擷取到網卡的MAC地址

另，貼上，判斷當前是否為wifi串連方式：

    //判斷當前是否使用wifi串連    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

/** * 通過callCmd("busybox ifconfig","HWaddr")擷取mac地址 * @attention 需要裝置裝有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;        }                //對該行資料進行解析        //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：

   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;       } 

這個需要裝置支援busybox工具。現在發現一些裝置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地址的檔案“/proc/net/arp”

需要有這個檔案，並且記錄了相應的內容

   /**       * 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;    }

 

 /**     * 以行為單位讀取檔案，常用於讀面向行的格式檔案     */    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","以行為單位讀取檔案內容，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地址的檔案“/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~
