Android传感器计步器

暑假里做了一个安卓计步器，不依靠GPS，也不用联网，只依靠重力加速度传感器和三轴磁力传感器，就可以实现记录步数和记录行走轨迹。我还加入了摇一摇切歌的功能，享受运动的乐趣~~

发布的apk可以在这里下载：pan.baidu.com/s/1i3gw3sh （打算以后完备了再发布到应用市场，所以欢迎大家吐槽评论）

这个项目只用了三天时间（作为自己的第一个安卓作品，我觉得还是很快的~~），当时完全是被deadline给逼出来的。老师对这个项目赞不绝口，觉得我一个正在上预科的孩子，学校里C语言还没有开课，就能自己做得这么好，于是果断给99分，哈哈~~不过，我觉得这个项目有很多地方可以改进和完善，因此在这里把这个项目总结一下，以备查询，也欢迎大家给出意见。以后有时间，再推出2.0、3.0等版本咯咯~~

计步器的原理是基本的物理知识，不再赘述，以后有时间可以单独写一篇，说明我是如何推导的。下面是所有代码：
