Trying to get Android build with SDK bigger than 22

Languages Android
5

Hi @Montana,

I’ve been debugging some builds, and it appears the problem is one of virtualisation for the Android emulator, which limits us to only using an image with armeabi-v7a architecture. Which really limits the highest Android SDK you can build for as Google stopped supporting this architecture some time ago.

I can’t remember where I got the inspiration but searched for KVM and Travis and stumbled across:
https://travis-ci.community/t/add-kvm-support/1406
Which seems to have solutions to this problem, I believe i’ve used the following two links as templates:
