Failed running Android build with il2CPP with Unity 2019.2.11f1

Question

Hi,

We are looking to update our app on the google play store with 64 bit version and for that we updated our Unity to Unity version 2019.2.11f1. Have installed the latest android SDK along with NDK version 16b and are building using the "Build App Bundle(Google Play)" checkbox. Have also checked the ARMv7, ARM64, x86 check boxes under the configuration settings under player settings.

These are the errors that I get

First, I would not recommend building for x86, unless your application actually needs to work on Android x86 devices. Not building that architecture will save you build time.

The real issue is is that the EasyAR.dll assembly has a number of extern methods which require an implementation in a native library. The first is ezarRegisterLogFunc, but there are many others.

Do these methods have a native library for Android compiled for the architectures you want to use (ARMv7 and ARM64)? If so, that library should be in the build. If not, you can use #if statements in the EasyAR code to avoid compiling ezarRegisterLogFunc and similar methods on Android.

If this EasyAR library is from a vendor, please make sure they have a version that works with Android IL2CPP builds.

I checked with them, EasyAR supports IL2CPP Android builds and we are using the latest version of their SDK, still cannot solve this problem.

Interesting! Is there a native library where ezarRegisterLogFunc and the other functions are defined? That native library should be added in the Unity project as a native plugin.

I struggle with the same issue, I use EasyAR 3.0.1, it supports x64, but I'm getting absolutely the same issues. Have you solved it?
