New to Unity Android, trying to wrap my head around obb files

Hi everyone,

I’ve recently begun trying to publish an app to the Google Play store, and I’m a little confused as to what I am supposed to do as far as splitting it up. I was initially under the impression that all I needed to do was check the “Split Application Binary” button, and Unity and Google would handle the downloading automatically. However, now it’s looking like I need to use some sort of downloader to find and install the .obb file. Unfortunately, the documentation in the area is very sparse and often several years old. Can anyone give me a good overview or point me in the direction of a good tutorial for how to use the downloader?

Thanks for your help!

If your app is over 100 megs, you will split it up and it creates two files. You then will upload the apk and the obb file to Google play. Once that is done, you don’t have to do anything else. Google will handle both files when someone downloads the app. No need to create your own downloader.

Now, there are some things that might need to be moved from the obb file to somewhere else, like when using vuforia. I think this applies to files in the streamingassetspath in particular.
