Android 解压问题（getNextEntry（）抛UTFDataFormat Exception:bad byte at 0）(
java.io.UTFDataFormatException: bad byte at 12
Android zip解压网上的资料很多，但是我用时出现一个bug是getNextEntry（）抛异常java.io.UTFDataFormat
Exception:bad byte at 4。我找了好久最后发现，其实就是文件名不能是汉字。因为我的zip包里有带汉字的文件。这样Android就不够解压出现异常。Android解压的zip包不处理，里的东西不能是以汉字命名的。
