I was wondering if anyone has managed to use obb expansion files on Android with Cocos2D-X V3 and above ?
I have done this before on previous version of Cocos2D-X by editing Cocos2dxHelper.java as follows
Replace
Cocos2dxHelper.nativeSetApkPath(applicationInfo.sourceDir);
With
Cocos2dxHelper.nativeSetApkPath(Environment.getExternalStorageDirectory() + "/Android/obb/" + pContext.getPackageName() + "/main." + Settings.EXPANSION_VERSION + "." + pContext.getPackageName() + ".obb");
But this does not work any more.
Does anyone have any ideas why this no longer works and what to do instead ?
Thanks for any help
Hi,
It would be great if anyone post solution.
Thanks
Hello Gurudath,
To manage to get the expansion file to work after trying many solutions without success, I ended up editing CCFileUtilsAndroid.cpp and changing the file access functions with more or less the ones that were in Cocos2d-X V2.X
Hi Jonathan,
Did you find solution? Is it working after editing CCFileUtilsAndroid.cpp file?
Yes it is working now after changing the CCFileUtilsAndroid.cpp file.
I have created .obb file using JOBB tool. How to access .obb file and how to load resources in cocos2dx version 3. Can you please guide me?
Thanks a lot
I used the zip command to create the obb (remember if you have media files in the obb they must not be compressed).
As I said in my first message I edited Cocos2dxHelper.java
Here is my modified CCFileUtilsAndroid:
CCFileUtilsAndroid.zip (5.2 KB)
Otherwise for music and sound files you can follow what was done in this thread:
Here’s a gist of files. Updated to remove any of our game’s info.
I’m probably missing a few things, hopefully this will help in some way until a full tutorial with proof of example test (published in store) can be created and written by myself or another.
NOTE: This was developed with Cocos2dx 2.2.x so there are no guarantees it will work at all with 3.x. I’ll do the tutorial to example test app when I get time with 3.x for both our game’s update as well as hopefully others like yourself.

Hi,
Thank you for the solution.
Hi,
I tried with above solution. But am facing problem in loading image. I used zip command to create obb. Am not using any media file. Here is log that am getting. Am using ndk version 9d
12-09 16:39:34.550: D/CCFileUtilsAndroid.cpp(9304): asset is nullptr so not in apk
When i see log APK and OBB assets path are same. What may be problem?
Hello,
I think the problem is from the obb, the obb should be the assets folder zipped.
I have zipped the assets folder and renamed with .obb Am i doing anything wrong here. Is there any method to check if .obb file exist?
Hi,
Thanks for the solution. It works for me.
Regards
I just use the ‘zip’ command in the build process (in shell scripts).

Hi guys, sorry for lacking this feature.https://github.com/cocos2d/cocos2d-x/issues/9437 , to support obb file officially in the engine.
Hi Jonathan,
Did you tried for Music? Is it working?https://gist.github.com/stevetranby/3151c541a7ce17cbd9bc link. Am getting error while playing sound.
Thank you
Hello,
Yes I did the same changes for music as in the link (but I did not handle not using the expansion file so do not have the code where usingExpansionFiles is false).
Are your music file not compressed in the zip ?
Hi,
My music file is present in the compressed zip. Am getting file is present in OBB path as log. But am getting error.
AssetFileDescriptor assetFileDescritor = zip_resource_file.getAssetFileDescriptor( pPath );
In above line error message is generated. Sounds are not playing.
Regards
The music and sound files need to be in the obb but they must not be compressed (just stored in the zip, no compression applied to them).
You can do it with this command which does not compress m4a and mp3 files ($file is the name of the obb) :
Hello,
Thanks for the responce. I tried doing zip file using above command. But am getting same error. Where am doing wrong? Any idea?
