Coding AR to split .apk /.obb file job.

September 24, 2013 - 3:43am #1


We have an AR app here that was originally for an exhibition stand. It has video textures and pinch/zoom scenes also. Due to the videos the file size is around 300MB so we hired a coder to help us split the file into an .apk and a .obb in order to be able to have the app on the Play Store. Unfortuately the .obb code is fighting the AR code, possibly along the lines of this post:



...so that the AR never loads despite the GUI being visable.

We'd like you to amend the project we have so that we can have the app on the Store as soon as possible. 

Please email me at

if you are able to help us sort this quickly.

Thank you for your reply. That is the impression I get from the thread I was shown by David Beard. I was here offering work to anyone who could help as I'm not a coder. We have a client that gets more frustrated with every day that passes without the app being online and our development budget is dependent on them. We've already paid a Unity coder to do it but he hasn't worked with Vuforia, and he can get the basic downloader to function but the AR doesn't work and he hasn't yet finished the job. I was told this was the place to advertise but it seems no-one is able to help me get this done. If you could recommend someone who could help I would really appreciate it.

Hi, if this can help, I would suggest to check if you are implementing the following workflow (as it seems other developers have successfully implemented this):

  • download the OBB extension file and store it onto the device external storage (SDcard)
  • once the OBB file has been downloaded and saved, extract the Dataset files (XML and DAT) from it, and copy them to another directory, again on the external storage (SDcard), for example under /sdcard/mydatasets/
  • load the datasets from the external storage path as above

Hope this can help.
