Hi there, Mat from App Center Build team here - thanks for creating this gist. I'm not entirely sure it would work though, since it downloads the Linux version of the NDK, our build VMs are Macs - so it would need to download the "darwin" version.
Also, we are working on a fix to this - would love to chat if it works for you.

@ranterle this did not fix the issue for me as the script fails to execute at all. It was suggested to try by the appcenter support.

Everyone: try this updated version https://gist.github.com/ionut-movila/2e20565288e58d32277aa5df3b20d9b2
