首当其冲的就是烧录MAC,SN

有些厂家在SDK中没有提供相应的接口,对于不熟悉Linux的小白来说就是一潭深井,在不断与阿里大神谦卑的请教下.总算知道了原理
下面的方法适合所有安卓系统

首先在串口或者adb shell之后可以执行

//烧录有线MAC
echo mac > /sys/class/unifykeys/name
echo "00:00:00:00:00:00" >/sys/class/unifykeys/write
//读取MAC
echo mac>/sys/class/unifykeys/name
cat /sys/class/unifykeys/read
//烧录SN
echo sn> /sys/class/unifykeys/name
echo "55555555555555555" >/sys/class/unifykeys/write
//读取SN
echo sn>/sys/class/unifykeys/name
cat /sys/class/unifykeys/read

在软件开发中,聪(tian)明(zhen)的我百度了Andorid执行Linux命令
然后在代码中执行了

//exec()方法为Runtime.getRuntime().exec(command)
MyUtil.exec("echo mac > /sys/class/unifykeys/name");
MyUtil.exec("echo "00:00:00:00:00:00" >/sys/class/unifykeys/write");

其实原理就是读写文件

public static String readFile(String filePath) {
        try {
                StringBuffer fileData = new StringBuffer(1000);
                BufferedReader reader = new BufferedReader(new FileReader(filePath));
                char[] buf = new char[1024];
                int numRead=0;
                while ((numRead = reader.read(buf)) != -1) {
                        String readData = String.valueOf(buf, 0, numRead);
                        fileData.append(readData);
                }
                reader.close();
                return fileData.toString();
        } catch (IOException e) {
                //e.printStackTrace();
                Log.e(TAG, e.toString());
                return null;
        }
    }


public static void writeFile(String path,String value){
        BufferedWriter out = null;
        try {
                out = new BufferedWriter(new FileWriter(path), 32);
                out.write(value);
                out.flush();
        } catch (IOException e) {
                Log.e(TAG, "IOException when write " + path);
        } finally{
                try{
                        if(out != null){
                                out.close();
                                out = null;
                        }
                }catch(IOException e){

                }
        }
}

而烧录和读取MAC也就成了

public void setNetMac(String mac) {
        MyUtil.writeFile("/sys/class/unifykeys/name", "mac");
        MyUtil.writeFile("/sys/class/unifykeys/write", mac);
}

public String getNetSn() {
        String string="";
        MyUtil.writeFile("/sys/class/unifykeys/name", "sn");
        string=MyUtil.readFile("/sys/class/unifykeys/read");
        return string;
}

另外附带设置和获取系统Property属性

public static int setProperty(String paramString1, String paramString2)
    {
      try
      {
        Class localClass = Class.forName("android.os.SystemProperties");
        localClass.getDeclaredMethod("set", new Class[] { String.class, String.class }).invoke(localClass, new Object[] { paramString1, paramString2 });
        Log.e("设置telnet","Util-setProperty [" + paramString1 + "]=" + paramString2);
        return 0;
      }
      catch (Exception localException)
      {
          Log.e("设置telnet","Util-setProperty--Exception=" + localException.getMessage());
      }
      return -1;
    }
    public static String getProperty(String key,String defValue) {
        String value = "fail";
        try {
            Class<?> classProp = Class.forName("android.os.SystemProperties");
            Method method = classProp.getDeclaredMethod("get", String.class);
            value = (String) method.invoke(classProp, key);
        } catch (Exception e) {
            value = "fail";
        }
        return value;
    }
