Hi,
I’m working with FMOD and Unreal on a spatial audio project for Android using the Steam Audio spatialization plugin.
All these plugins should work well together but it looks like it doesn’t work as expected on android. I can’t load phonon.so files whereas they are into the lib folder of the apk.
- FMOD alone with unreal works well on android
- Steam audio alone with unreal works well on android
- FMOD and Steam audio work well on the Unreal editor and inside the mobile device preview. (On a windows machine)
- FMOD and Steam audio crash the app at startup on Android
Just a few info about the configuration :
- I created a \*\*\_APL.xml file to copy the phonon.so and the phonon\_fmod.so files into the apk as expected int the fmod documentation : www.fmod/docs/2.02/unreal/platform-specifics.html
- I checked into the apk file, the phonon\_fmod.so and phonon.so are inside the lib folder. (to be precise the libphonon.so and the libphonon\_fmod.so → lib prefix looks like it is added during copy)
When I start the android .apk It crashes after the splash startup image.
I get this Log error at startup :

(Don’t worry about the resonance audio plugin)
I noted two things :
- I find a bit strange the location where it searches for the libphonon\_fmod.so ( “…/…/…/Production\_Project/Plugins/FMODStudio/Binaries/Android/arm64-v8a/libphonon\_fmod.so”) because it looks like to be the search path of the computer.
- I never saw any file phonon\_fmod64.so into any of the library of steam audio.
Other infos :
- FMOD studio Version : 2.02.10
- Unreal Engine version : 4.27
- Steam audio version : 4.11.1
- Steam audio Support for FMOD version : 4.11.1
IN FMOD :
- steam audio plugins for fmod studio installed into the fmod Project folder and fmod configured for mobile
- fmod configured for mobile platform
Source : [Getting Started — Steam Audio FMOD Studio Integration documentation](https://valvesoftware.github.io/steam-audio/doc/fmod/getting-started.html)
IN UNREAL :
- FMODStudio, SteamAudioFMODStudio and SteamAudio plugins installed into the Game directory
- the Source/Project/Project.Build.cs contains SteamAudio as PublicDependencyModuleNames
Source : [Getting Started — Steam Audio FMOD Studio Integration documentation](https://valvesoftware.github.io/steam-audio/doc/fmod/getting-started.html)
Any ideas of what could be missing in the configuration?
Thanks a lot for your help!

Hi,
Thank you for the detailed post, it does seem you are doing everything correctly. Is it possible to get a copy of the project uploaded to your profile to test on our side?

Hi,
Thank you for providing the project and for your patience.

You are right, the SteamAudio plugin is trying to load files from the wrong directory and causing the crash.

As here you can see FMOD has successfully loaded the plugin.
Unfortunately, I do not have a solution to the issue. You could post the issue on the Steam Audio GitHub page here: [GitHub - ValveSoftware/steam-audio: Steam Audio](https://github.com/ValveSoftware/steam-audio).
Again, thank you for your patience and I am sorry I can’t assist further.

Thanks a lot for your time !
Sad to see it didn’t worked.
I will post an issue on the Steam Audio Forum.
Have a nice day !
