il2cpp android build error 2019.2.19f1

blamejane · November 7, 2019, 4:54am

I am having a tough time with my Android build. The 32 bit mono apk worked, but google play requires a 64 bit version. The iOS build went fine as well. As soon as I switched to il2cpp I started having build errors. I’ve tried read the build log, and have searched the forums, trying lot’s of solutions, but nothing seems to work.

I’ve tried internal build as well as gradle. I’m unchecked all architectures except 64 bit. I’ve deleted the Library folder, deleted .sln files, deleted Temp folder.

I’m on a mac and I have Admin privileges. I have the latest version of unity as well as the android sdk/ndk from unity install.

If anyone could look at this log, I have no idea what to try next.

So I solved this by manually downloading Android NDK r16b. For some reason the Unity Hub downloaded and installed version was causing problems. I installed the NDK in a different directory and pointed the Unity → preferences → External Tools → NDK directory to this new install.

Immediately was able to Export for Android Studio as well as build the APK for Google Play within Unity. Freakin’ Yay!
