Android 解壓問題（getNextEntry（）拋UTFDataFormat Exception:bad byte at 0）(

?

java.io.UTFDataFormatException: bad byte at 12

?

Android zip解壓網上的資料很多，但是我用時出現一個bug是getNextEntry（）拋異常java.io.UTFDataFormat

Exception:bad byte at 4。我找了好久最后發現，其實就是文件名不能是漢字。因為我的zip包里有帶漢字的文件。這樣Android就不夠解壓出現異常。Android解壓的zip包不處理，里的東西不能是以漢字命名的。
