Using Nvidia Blast in Android Build with Unity3D

Hey all.

I am making an Android game with Unity3D. The game uses the NvBlast library and everything works fine when I start the game in the Unity Editor. But when I build the game for Android, I always get an DllNotFoundException for NvBlastExtUnity_x64. I only have the dll’s and couldn’t find any .so files which should work better, but the Unity forums suggested that Unity can run Dll’s on Android so I guess, that can’t be the problem.

Does anyone of you had a similar problem, while using Blast and Android? Or any suggestions?
