[Solved] IL2CPP android build ARMv7 + ARM64 --FAILS

Hi All,

if build the app with
- Mono only, no problems,
- IL2CPP ARM64 only, no problems,
- IL2CPP ARMv7 + ARM64 build fails.
I tried all solutions on the forum here, no luck. Help?

The culprit was the IOS version of the iBeacon plugin (Underlined in the log). I am removing it for the Android builds and everything works.

error1:

Ran into this issue today. This was the first link on google. It fixed things immediately. You saved me a lot of time. Thanks!

 

SO HOW DID YOU SOLVE IT PLEASE?

 

what you've done to resolve this issue has been bothering you for a week (

 

For il2cppcore.dll errors from Facebook SDK, update your sdk using https://developers.facebook.com/docs/unity/upgrading-7.x and not from Unity Asset Store (its usually not as updated)
