一、引言
最近在做移动发布平台，其中有一个功能，需要上传apk/zip/ipa包文件并拿到各个包所对应的版本号和版本编号。不用解压文件，而是直接读取文件流，从文件流中解析得到数据。
代码也是自己从网上各个地方找然后汇总并测试通过的，中间也踩过一些坑，就当记录一下，不喜勿喷。
二、工具类说明：
该工具类有三个解析方法parseZip、parseApk、parseIpa。解析的代码就在下面，测试过，不用多说，拿来就能用。此处要说一下需要的依赖包。parseApk需要一个AXMLPrinter2.jar包，这个包在Maven仓库里没有，需要自己找，然后在Maven工程里外部依赖，如果不是Maven工程那就太简单了吧。parseIpa需要一个dd-plist.jar，这个包在Maven仓库里可以找到，直接添加依赖就好了。
