无法从 Android 上创建的 ZIP 存档中提取文件（特定于设备/操作系统）

我正在 Android 上使用如下代码创建存档：

    OutputStream os = new FileOutputStream(zipFile);
    ZipOutputStream zos = new ZipOutputStream(new BufferedOutputStream(os));
    try 
    {
        zos.setLevel(8);
        byte[] buffer = new byte[32768];
        for (VFile src : toPack)            
        {
            ZipEntry entry = new ZipEntry(src.name);
            zos.putNextEntry(entry);
            src.pushToStream(zos, buffer);
            src.close();
            zos.closeEntry();
        }
    }
    finally 
    {
        zos.close();
    }       

我发现只有一种压缩方法可用 -DEFLATED（只有STORED可用替代方案）。这意味着存档始终使用一种方法进行压缩。

如果我在 Android 2.3.4 上运行此代码 - 我可以使用 7Zip 在 Windows 中解压缩文件；如果我在 Android 3（或 Samsung Galaxy Tab；不确定是谁弄错了）上运行此程序 - 7Zip 显示存档列表，但无法解压缩文件并显示不支持的压缩方法。同时7Zip显示Deflate作为文件的压缩方法，这意味着它可以正确处理它。

有人遇到这个问题吗？

Thanks.

UDP：找到另一个具有类似问题的主题（但可能不一样）。

@user1269737的答案是正确的；几乎。但它仅适用于单个文件档案。 下面是解析整个档案的代码。
