Cannot build for Android on Unreal Engine 4.25 (Wwise Integration 2019.2.4.7329.1721)

Question

Hi

I'm hoping someone can shed some light on this situation. I can build my test project for Windows or Mac, but not Android.

When building for Android, I get the following error:

LogPlayLevel: Error:   ERROR: Unable to instantiate module 'AkAudio': System.IO.DirectoryNotFoundException: Could not find a part of the path 'D:\UnrealProjects\Games\Runner\Plugins\Wwise\ThirdParty\Android\armeabi-v7a\Profile\bin'.

I have tried all the usual UE4 tricks - regenerate project, deleted cache folders, etc. I've also reinstalled the Wwise integration - no change.

I do not have a folder called D:\UnrealProjects\Games\Runner\Plugins\Wwise\ThirdParty\Android\armeabi-v7a\Profile\bin on my system. I DO, however, have a folder called D:\UnrealProjects\Games\Runner\Plugins\Wwise\ThirdParty\Android_armeabi-v7a\Profile\bin. This was created by the Wwise integration, but it appears to be looking for it in Android\armeabi-v7a instead of Android_armeabi-v7a. Unless that's a completely different folder, but the folder it's looking for doesn't exist.

Any ideas how to fix this?

Answer 1

I just came across this today in my project and there are two options:

1. Move the Android_armeabi-v7a contents into a folder that it's looking for (Android\armeabi-v7a)
2. Open up AkAudio_Android.Build.cs and change line 14 from #if UE_4_25_OR_LATER to #if !UE_4_25_OR_LATER (there is a missing exclamation point at the beginning)

I went with the second option but I don't know if it requires a recompilation of the plugin (I did it anyway). If you don't have Visual Studio installed then you would need to go with the first option.

Update: Ran into some other issues then found this https://www.audiokinetic.com/library/edge/?source=UE4&id=pg_important_migration_notes_2019_2_2.html so you are supposed to move the folders into what it expects.
