Ml-agents: Can't build for Android with 0.6

[13Flo]

Since I upgraded to 0.6, I get these errors when trying to build for Android:

Any idea how to fix?

i have this problom too, when i upgrade from 2017.3 to 2018.3. so how to slove it~

I figure out that removing all the System.XXXX.dll from ML-Agents/Plugins/Android fixes the issue.

Edit: I'm not closing the issue so developers can fix

Hi @13Flo

Thanks for pointing this out. We will be updating our inference solution for the next release of ML-Agents, and will ensure it is functional under Android without this issue.

Hi all. We are now using the internal inference solution. Closing this issue for now. Please feel free to re-open if you deem it necessary.
