有什么建议吗？

解决方法:

根本原因分析：

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

当Fat16RootDirectory变满或ClusterChainDirectory超出其ClusterChainDirectory的最大大小(512 MB)时,就会发生此错误

异常发生在哪里？ ：DirectoryFullException.java

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

对于这个问题,我希望有一个解决方案和一些建议.希望对您有所帮助.

方案1：

在Windows上：如果您的文件夹“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

而你用

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

您将得到提到的错误.尝试添加一个目录层次结构并将“数据”目录创建到子文件夹

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

采用

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

您必须牢记,如果以后要阅读Obb,则图片现在位于子文件夹中.

> What causes jobb tool to throw FAT Full IOException?

Suggestion-1:

要检查扇区/群集/ FAT大小,请运行“ jobb -v -dump [obb]”.这将打印一堆信息,包括“每个群集的扇区”和“每个FAT的扇区”.

在我的旧.obb文件中,这些值分别为8和150. 8不是150的倍数,因此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来解决此问题.使用Google云端硬盘上的当前库版本,我现在每个群集获得8个扇区,每个FAT获得184个扇区.

我尚未验证这是否可以解决我之前看到的数据损坏问题.我将进行更多测试,并在此处报告.

建议2：

Hacking can solve the issue.但是占用了更多的内存：

这个问题的确开始变得非常无聊.今天,我有点想出了一个解决办法,这很荒谬,但是看起来好像向.obb添加额外数据似乎可以解决问题(至少对我而言).确切地说,我的原始.obb文件大小为110MB,现在为220MB,应用程序读取数据时不会损坏.到目前为止,这是我迄今为止对应用程序所做的最肮脏的黑客攻击,对此我并不感到骄傲,但是,至少现在正在运行. ：p

建议-3：

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

该版本解决了与Android SDK一起发布的JOBB工具(自Android SDK 23开始)产生的问题,该工具无法生成大于512M的OBB文件.

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：

>原始版本提供https://github.com/waldheinz/fat32-lib/
>可在以下位置获得修改版本
https://android.googlesource.com/platform/external/fat32lib/

要从源代码制作jar文件,可以按照以下教程进行：

> Gradle – Create a Jar file with dependencies
