java - JOBB DirectoryFullException : de. waldheinz.fs.fat.DirectoryFullException: 目录已满

Question

我正在尝试在包含 192 个 jpg 文件(总计约 70 MB)的目录中使用 JOBB 工具。当我以 jobb -d C:/sdk/tools/dir/data -k 123456 -o com.nick.app.obb -pn com.nick.app -pv 1 运行命令时，它会生成以下日志:

对此有什么建议吗？

Answer 1

根本原因分析:

de.waldheinz.fs.fat.DirectoryFullException: directory is full

此错误发生在 Fat16RootDirectory 变满 或 ClusterChainDirectory 超出其最大大小 (512 MB)

异常从何而来？ : DirectoryFullException.java

DirectoryFullException(int currentCapacity, int requestedCapacity) {
    this("directory is full", currentCapacity, requestedCapacity);
}

对于这个问题，我想推荐一个解决方案和一些建议。希望对您有所帮助。

解决方案一:

在 Windows 上:如果你有一个丢失图片的文件夹“data”，并复制到 android sdk-tools 目录

data/1.jpg
data/2.jpg
data/3.jpg
data/...
data/5000.jpg

你用

console>>>jobb -d C:/sdk/tools/dir/data -k 123456 -o com.nick.app.obb -pn com.nick.app -pv 1

您将收到上述错误。尝试添加一个目录层次结构并将“数据”目录设为子文件夹

root/data/1.jpg
root/data/2.jpg
root/data/3.jpg
root/data/...
root/data/5000.jpg

使用

console>>>jobb -d C:/sdk/tools/dir/root/data -k 123456 -o com.nick.app.obb -pn com.nick.app -pv 1

你必须记住，如果你想稍后从 obb 中读取，图片现在位于子文件夹中。

Suggestion-1:

要检查 sector/cluster/FAT 大小，请运行 "jobb -v -dump [obb]"。这将打印一堆信息，包括 "Sectors per cluster" 和 "Sectors per FAT"。

在我的旧 .obb 中，这些值分别为 8 和 150。 8 不是 150 的因数，所以我可能遇到了上述内核错误。

您需要确保使用更新的 jobb.jar 和 fat32lib.jar 来修复该问题。使用 Google Drive 上当前版本的库，我现在每个集群有 8 个扇区，每个 FAT 有 184 个扇区。

我还没有验证这是否解决了我之前看到的数据损坏问题。我会做更多的测试并返回这里报告。

建议2:

Hacking can solve the issue 。但是占用了更多内存:

这个问题确实开始非常非常无聊了。今天我想出了一个解决方法，这很荒谬，但看起来向 .obb 添加额外数据似乎可以解决问题(至少对我而言)。准确地说，我原来的 .obb 文件大小是 110MB，现在是 220MB，应用程序读取数据时没有损坏。到目前为止，这是我对应用程序做过的最肮脏的黑客攻击，我并不为此感到自豪，但是，嘿，至少现在可以用了。 :p

建议三:

2015 年 10 月 19 日，他们发布了更新版本:android-sdk-fat32lib

此版本 fork 解决了从 (Android SDK 23) 开始随 Android SDK 分发的 JOBB 工具无法生成大于 512M 的 OBB 文件的问题。

更新:

您将在以下部分获得原始版本和修改版本的源代码:

• https://github.com/waldheinz/fat32-lib/ 提供原始版本
• 修改版本可在 https://android.googlesource.com/platform/external/fat32lib/
