Since Greg mentioned me: Instructions/commands I came up with and that I sent over to Gregory should attempt using API level 23. Totally arbitrarily picked. Use of pre-21 API is not happening so not an issue.
Needless to say, building works for me. I don’t have a self-contained script to share, but it’s super simplistic and what Greg described (incl using GUI to install NDK) is what I did. I’m only sure it builds, not that it works, as I am yet to try running the code; I don’t have a build script ready for producing an APK (the old approach from 2013 and 2014 is a mess and needs to be reworked).
