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

我正在尝试在包含192个jpg文件的目录上使用JOBB工具，总共大约70 MB。 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：

有什么建议吗？

Answer 1

根本原因分析：

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

Fat16RootDirectory becomes full或ClusterChainDirectory grows beyond it's ClusterChainDirectory's maximum size(512 MB)时发生此错误

从哪里发生例外？ ： DirectoryFullException.java

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

对于这个问题，我想更喜欢解决方案和一些建议。 希望它可以帮到你。

方案1：

在Windows上：如果你有一个文件夹“数据”丢失图片，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 

你会得到上面提到的错误。 尝试添加一个目录层次结构，并将“数据”目录设置为子文件夹

 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 

你必须要记住，如果你想稍后从obb中读取，那么这些图片现在都在子文件夹中。

建议1：

要检查sector/cluster/FAT大小，请运行"jobb -v -dump [obb]" 。 这将打印出一堆信息，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的因素，所以我可能已经遇到了上面描述的内核bug。

您需要确保使用更新的jobb.jar 和 fat32lib.jar来解决该问题。 使用Google Drive上的当前版本的库，我现在每个群集有8个扇区，每个FAT有184个扇区。

我还没有validation这是否修复了我之前看到的数据损坏问题。 我会做更多测试并在此报告。

建议2：

黑客攻击可以解决问题 。 但需要更多的记忆：

这个问题确实开始变得非常无聊。 今天我找到了一个解决方法，这很荒谬，但看起来像.obb添加额外的数据似乎解决了这个问题（至少对我而言）。 确切地说，我原来的.obb文件大小是110MB，现在是220MB，应用程序读取数据没有损坏。 到目前为止，这是我曾经对应用程序做过的最脏的黑客，我不为此感到骄傲，但是嘿，至少现在正在工作。 ：p

建议-3：

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

此版本分叉解决了与Android SDK一起分发的JOBB工具(Android SDK 23)无法生成大于512M的OBB文件的问题。

更新：

您将在以下部分中获得原始版本和修改版本的源代码 ：

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

要从源代码制作jar文件 ，您可以按照教程：

2. Gradle – 创建具有依赖项的Jar文件
