Countly下载的原工程中，如博客http://blog.csdn.net/changemyself/article/details/12653151，所说的，一共只有两个包，一个管理UDID的，一个是Countly的核心。
首先说一个巨大的变化，不同于上面博客的是，我与2014年7月下载Countly Android SDK，其记录缓存机制已经不使用数据库，而全部改用SharedPreference，使得容错能力获得极大提高。
下面先贴出我修改后的工程结构：
OpenUDID包我没有做修改，还是沿用原来的源码，
countly包:
CountlyStore.java,DeviceInfo.java,UploadUtils.java三个文件都是辅助类，Countly是核心类，首先简要了解三个辅助类的源码
UploadUtils.java 是我自己添加了post上传的封装方法，就是post上传,就占用篇幅了。
DeviceInfo ： 主要是获取手机中的各类信息，其中的channel表示市场渠道号，是自己在manifest的metadata里定义的
而getMetrics是对外的主要方法，可以把信息收集起来，并做成json字符串的格式
class DeviceInfo {
//---------------自定义meta-------------------

/**

CountlyStore：
注意其数据存储的方法，都是每次把全部数据从pref里取出，整体修改，然后再整体替换的。由于数据其实不大，实际占用的data控件也就上百k，这样简化了操作，规避了数据库的适配危险，程序也比以前的版本好读多了。

注意源码中的几点：
1 connection对象和event对象分别对应app自己的生命和用户记录的event，两者在记录的时候，是使用两个不同的queue，但是在上传的时候，统一使用connection队列，recordEvent的时候会把event加入的connection中，onTick里是唯一的上传通道。
2 里面的Crash和feedback是我自己额外加的，原来只有通用的对象
3 为了防止溢出，我加入了规避的情况，即多次发送不成功后，回将最早的部分记录删除掉，避免一直不联网的情况下，pref的数据无限变大。
第二个包openUDID也是个开源包，目的是为了获得设备唯一的一个UDID，如果获取不了，会随机生成一个。
