如何使用Java代码获取Android移动终端Mac地址

        快下班了，现在总结一下如何使用Java代码获取Android移动终端Mac地址：

        通过设备开通WiFi连接获取Mac地址是最可取的，代码如下：

	/**
	 * 设备开通WiFi连接，通过wifiManager获取Mac地址
	 * 
	 * @author 高焕杰
	 */
	public static String getMacFromWifi(Context context){
		ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
		State wifiState = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState();
		if(wifiState == NetworkInfo.State.CONNECTED){//判断当前是否使用wifi连接
	        WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);   
	        if (!wifiManager.isWifiEnabled()) { //如果当前wifi不可用  
	        	wifiManager.setWifiEnabled(true);
	        }
	        WifiInfo wifiInfo = wifiManager.getConnectionInfo();
	        return wifiInfo.getMacAddress();
		}
        return null;
	}

        1、通过调用Linux的busybox命令获取Mac地址：

	/**
	 * 通过调用Linux的busybox命令获取Mac地址
	 * 
	 * @author 高焕杰	
	 */
	private static String getMacFromCallCmd(){
        try {
        	String readLine = ""; 
        	Process process = Runtime.getRuntime().exec("busybox ifconfig");
            BufferedReader bufferedReader = new BufferedReader (new InputStreamReader(process.getInputStream()));
            while ((readLine = bufferedReader.readLine ()) != null) {//执行命令cmd，只取结果中含有"HWaddr"的这一行
            	if(readLine.contains("HWaddr")){
            		return readLine.substring(readLine.indexOf("HWaddr")+6, readLine.length()-1);
            	}
            }
        }catch(Exception e) {  //如果因设备不支持busybox工具而发生异常。 
            e.printStackTrace(); 
        }
        return null;
	}

        2、通过查询记录了MAC地址的文件（文件路径：“/proc/net/arp”）获取Mac地址：

/**  
	 * 通过查询记录了MAC地址的文件（文件路径：“/proc/net/arp”）获取Mac地址
	 * 
	 * @author 高焕杰
	 */
    private static String getMacFromFile(Context context){
    	String readLine ="";
        BufferedReader bufferedReader = null;
        try {
        	bufferedReader = new BufferedReader(new FileReader(new File("/proc/net/arp")));
            int rollIndex = 0;
            while((readLine = bufferedReader.readLine())!=null){
            	if(rollIndex == 1){
	            	break;
            	}
            	rollIndex = rollIndex + 1;
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (bufferedReader != null) {
                try {
                	bufferedReader.close();
                } catch (IOException e) {
                	e.printStackTrace();
                }
            }
        }
        if(readLine !=null && readLine.length()>1){
        	String[] subReadLineArray = readLine.split(" ");
        	int rollIndex = 1;
    		for(int i = 0; i < subReadLineArray.length; ++i){
            	if(!TextUtils.isEmpty(subReadLineArray[i])){
            		if(rollIndex == 4){
            			return subReadLineArray[i];
            		}
            		rollIndex = rollIndex + 1;
            	}
            }
        }
    	return null;
    }
