I can’t seem to get FMOD working properly with quest shipping build through Unreal. My app just crashes before it even opens. The sounds work just fine through local development build.

I couldn’t find proper documentation for Unreal 4.23 on how to set up FMOD properly with Android builds.

Thanks!

The only two things to note should be:

- Make sure the integration is installed in the project and not the engine’s plugin directory.
- [Additional steps](https://fmod.com/resources/documentation-ue4?version=2.0&page=platform-specifics.html#android) will be required for plugins on Android.

Are you able to get any logging from the device?

I had the same issue, it works for some reason now…

What version of FMOD were you using when you got the crash?

Mine still doesn’t work. This is what I’ve tried including in my \_APL.xml file. I am not sure what I am doing wrong. I am using the latest version of FMOD so and plug in files.

The app and sounds work just fine when I launch from within Unreal editor. The app continues working after even if I download it from Dashboard. However, if I clear all of that data and have a fresh install from Dashboard the app crashes. I only have few normal FMOD Ambient sound events set up. Nothing too complicated.

You should not need to add the FMOD libs to this as they are already specified in the FMODStudio\_APL.xml.

Are you able to get any logging from the device at all?  
What version of FMOD are you using?

Hi lemonsprinkles, we’ve just found a bug which was the likely cause of your issue. A fix will be included in the next release of the FMOD Studio UE4 integration.

The fix has been pushed to GItHub already ([https://github.com/fmod/ue4integration](https://github.com/fmod/ue4integration)) so you can grab it from there immediately if you like.

It should also be possible to workaround the issue by changing the “Built bank file separation” setting in your FMOD Studio project. Changing the setting to either “Build metadata and assets to separate banks” or “Build metadata, non-streaming assets, and streaming assets to separate banks” should avoid the issue.
