for android build, it seems you need Android NDK r15c and a supported JDK, apparently 11, but you also have to fix the compilation of pcre using these changes https://github.com/HaxeFoundation/hxcpp/pull/1042/files because it won't compile otherwise
other than these I followed the same instructions on your gitgud page, just with `lime setup android` at the end of the installs, and you need to install the prereqs and assign the directories it asks for (Android SDK, Android NDK [from above], and Java JDK)
and I actually managed to get a compiled version on my phone from that
