1.简单暴力直接上代码

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        TextView tv_mac= (TextView) findViewById(R.id.tv_mac);
        tv_mac.setText("本机的mac地址"+getDeviceInfo(this));
        Log.e("mac",getDeviceInfo(this));
    }
    private  String getDeviceInfo(Context context) {
        try {
            String mac = null;
            FileReader fstream = null;
            try {
                fstream = new FileReader("/sys/class/net/wlan0/address");
            } catch (FileNotFoundException e) {
                fstream = new FileReader("/sys/class/net/eth0/address");
            }
            BufferedReader in = null;
            if (fstream != null) {
                try {
                    in = new BufferedReader(fstream, 1024);
                    mac = in.readLine();
                } catch (IOException e) {
                } finally {
                    if (fstream != null) {
                        try {
                            fstream.close();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }
                    if (in != null) {
                        try {
                            in.close();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }
                }
            }
            return mac;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
