[RESOLVIDO] Erro Build il2cpp

Eai abigos, seguinte, faz um bom tempo que não publico nada na playstore ai fui atualizar um app meu e vi que tem que mudar a arquitetura para ARM64.
https://blogs.unity3d.com/2017/12/20/meeting-google-play-requirements-in-the-future/

alterei desse modo


mas me da esse erro...

Código:

Mas você está compiilando para os 3? Eu geralmente compilava somente para um, ou armV7, ou x86, sei lá.

O seu SKD e JDK estão instalados?

Está usando EasyAR? Se sim, pelo que andei lendo, IL2CPP não oferece suporte.

Sim marcos está tudo correto com o sdk e o ndk.
Vc estava certo @artplayer, era o EasyAR mesmo, eu estava usando a versão 2, ainda não tinha suporte para 64, atualizei e funcionou, Vlw!!!
