Also i have tried with ZipResourceFile but i had the same error. You can try to mount and unmount your obb file with this class: https://gist.github.com/Clockers/11af3c136b5d283f3560

My obb is created using JObb on a folder containing the file, you can find it here: http://developer.android.com/tools/help/jobb.html

I got a solution, create obb file without using of jobb command, using jobb command it create encrypted obb file, there is no need to create encrypted obb file

I am uploading unencrypted obb file to playstore, here, are steps to create unencrypted obb file

copy you resources files into a folder
create zip file of your resource folder (main.[version_code].[package_name].zip)
rename your zip folder with name (main.[version_code].[package_name].obb)

now, obb file is ready to upload on play store

Its help for me
