Set the input directory for creating an OBB file, or the output directory when extracting ( -dump ) an existing file. When creating an OBB file, the contents of the specified directory and all its sub-directories are included in the OBB file system. Specify the filename for the OBB file.
An OBB file is an expansion file used by some Android apps distributed using the Google Play online store. It contains data that is not stored in the application's main package (. APK file), such as graphics, media files, and other large program assets. OBB files are often stored in a device's shared storage folder.
These expansion files can be any format (like ZIP, PDF, MP4, etc..), but are most often OBB files created using the JOBB development tool. Structure: OBB files are are an encapsulated and encrypted set of resource files and subsequent patches for that set.
You can also get following error with the jobb-Tool (at least in windows with the jobb.bat), if you have many many files.
de.waldheinz.fs.fat.Directory Full Exception: directory is full
This is, because the obb file format is saved in FAT16, whitch only allows 512 entries/files in the root directory
On Windows: if you have a folder "data" whith lost of pictures, and copied to the android sdk-tools directory
and you use
console>>>jobb -pn my.package.name -pv VERSIONCODE -d ./data -k obb_password
-o main.VERSIONCODE.my.package.name.obb
you will get the mentioned error. Try to add one directory-hierarchy and make the "data"-directory to a subfolder
use
console>>>jobb -pn my.package.name -pv VERSIONCODE -d ./root -k obb_password
-o main.VERSIONCODE.my.package.name.obb
you have to keep in mind, that if you want to read from the obb later, that the pictures are now in a subfolder.
