我在使用zip4j库在android中生成zipfile时遇到问题,这里是代码:
try {
ZipFile zipFile = new ZipFile(dest);
zipFile.setFileNameCharset("GBK");
if (srcFile.isDirectory()) {
zipFile.addFolder(srcFile, parameters);
} else {
zipFile.addFile(srcFile, parameters);
}
} catch (Exception e) {
e.printStackTrace();
}
我得到了异常消息:
net.lingala.zip4j.exception.ZipException: Probably not a zip file or a corrupted zip file
at net.lingala.zip4j.core.HeaderReader.readEndOfCentralDirectoryRecord(HeaderReader.java:179)

此代码在Eclipse中适用于本地文件,但在Android中效果不佳,我很确定目标.zip路径是正确的,zip4j库版本是1.3.2。
任何人都可以给我任何建议吗?

我遇到了非常相似的堆栈跟踪。但是,我在桌面上使用版本1.3.2中的java和zip4j。我不确定我的答案与android有什么关系,但在这里它会发生。

我像这样使用zip4j
Path destination = Files.createTempFile("export", ".zip");
ZipFile zip = new ZipFile(destination.toFile());
要解决问题我改为
File destination = new File(System.getProperty("java.io.tmpdir"), UUID.randomUUID().toString());
ZipFile zip = new ZipFile(destination);
不同的是Files.createTempFile()创建空文件,文件必须搞砸ZipFile
的构造函数。当我以未占用的路径通过File
时,问题就消失了。
