经过连续几天的编制，安卓手机代码终于完成了，目前已经将我宿舍，家里，集控室的红外遥控电气设备完好的遥控了，另外还遥控了我的D7000相机，不错终于完工了。 代码分为二类： 各种电视、相机、等等遥控编码最简单，只要将按键的编码复制下来，直接变成手机发射码就可以了。（这种编码单个按键只发射单个信息） 最难的是空调编码，由于空调编码是将单个按键要发射所有控制信息，如增加一度温度，同时要将控制模式、温度、风量等等所有信息一同发射出去，还有检验码，通过长时间实验，如果像一般模仿遥控器的设备（例如万能遥控器）编码是将各种组合分别保存起来，这要就很长，也很麻烦，但用第一种方法实现起来就很容易。第二种方法主要是找规律比较麻烦，而且要再程序中变成组合再变成安卓发射码，比较麻烦。 经过摸索 格力遥控器编码规则如下（前面的资料是网上搜集来的，这里是自己总结的）：
