java - 打包和解包 *.obb 文件

Question

美好的一天!

假设我有一个名为 test 的目录。它包含几个目录和文件。(dir_1:file_1，file_2；dir_2:file_1，file_2；...；dir_5:file_1，file_2；)

我愿意 jobb -d ./test -k key -o data.obb -pn com.example.obbtest -pv 1

得到

文件已准备就绪。比，如

http://developer.android.com/tools/help/jobb.html

我愿意

jobb -d ./dotest/ -o data.obb -k key -pn com.example.obbtest -pv 1

并得到:

我想这意味着我没有包装错误。我该如何解决？

更新

我愿意 jobb -d ./test/-o my-app-assets.obb -pn com.examlpe.obbtest -pv 1 -k 11111111

很好

比 jobb -dump my-app-assets.obb -d ./undo/-k 11111111

然后我得到了我的文件。但是 - 它们都小于 1 mb。如果我添加大于 1 mb 的文件，我会得到

Answer 1

我不能说出你所有的错误，但知道相对路径导致 boot sector says there are 0 sectors per FAT 对我来说。使用 C:\fullpath\dotest\ 有效。
