Android获取本机唯一序列号和可变UUID方法

UUID+设备号序列号 唯一识别码（不可变）

private String getMyUUID(){

  final TelephonyManager tm = (TelephonyManager) getBaseContext().getSystemService(Context.TELEPHONY_SERVICE);   

  final String tmDevice, tmSerial, tmPhone, androidId;   

  tmDevice = "" + tm.getDeviceId();  

  tmSerial = "" + tm.getSimSerialNumber();   

  androidId = "" + android.provider.Settings.Secure.getString(getContentResolver(),android.provider.Settings.Secure.ANDROID_ID);   

  UUID deviceUuid = new UUID(androidId.hashCode(), ((long)tmDevice.hashCode() << 32) | tmSerial.hashCode());   

  String uniqueId = deviceUuid.toString();

  Log.d("debug","uuid="+uniqueId);

  return uniqueId;

 }

java 获取可变UUID

 private String getMyUUID(){

  UUID uuid = UUID.randomUUID();

     String uniqueId = uuid.toString();

   Log.d("debug","----->UUID"+uuid);

    return uniqueId;

   }

获得的格式：如下样子
