UE4 Android and 64 bit builds

Unreal Engine
1

Hi,
I tried to build my game with 64 bit enable and FMOD plugin turned on.

I changed armeabi-v7a folder name to arm64-v8a and start packaging.

I received following error:

You can’t just copy the libraries for a different platform. Check out this page:

http://www.fmod.org/documentation/#content/generated/engine_ue4/deployment.html

And look for the “Deployment on other Android architectures”. You can download the “Programmers API for Android” from FMOD and copy the libraries over for the extra platforms you want to use.

OK, it works now. Thank you! :slight_smile:
