替换友盟更新的小demo

友盟更新将在2016-10-15停止更新

友盟更新将在2016-10-15停止更新，之前一直使用友盟更新的小伙伴们是不是正在忙着相应对策，

友盟更新替换友盟提供了两种更新替换方式，    一个是使用推送将自己的新版本的下载链接推送到客户端，然后客户通过点击通知栏进行更新，这只是最简洁的处理方式，但是略显low，    接下来就是第二种方法，

在闪屏界面请求服务器查询是否有新版本

大致思路

1.在闪屏界面，请求服务器2.服务器返回服务器上面最新的版本的相关的信息，包含版本信息，描述信息，是否是强制更新……3.获取本地的已经安装的软件的版本号，与服务器返回的版本号进行比对4.如果本地的版本号小于服务器，则说明需要更新5.弹出对话框提示有新版本，询问用户是否更新6.用户点击确定更新，开启更新服务，下载新版的APK7.下载完成，安装APK，完成版本更新

这是开启的下载的服务的相关代码
