Hello,
I see plenty of documentation around building Pulse for Android when using it in Unity or Unreal projects, but I was curious if there was anything regarding native Android/iOS?
My assumption is that achieving this would require cross compiling a .so and then including it in the Android project structure.
Any guidance that saves me some headache would be greatly appreciated! Thank you!
Cross compiling instructions for android and ios
These instructions will build the targeted native .so files (we just drop them in Unity and Unity knows what to do with them) but they should also work in other application builds
Thank you that is very helpful.
Following that section for Android I run in to the following error:

Should I have to do something to the docker to enable Python?
Are you building integration or stable?
stable
We provide xcomplie.bat/.sh scripts that call the dockcross containers for you
But if you want to call it all yourself, just follow what is done in xcompile.cmake and dockcross.cmake, which does turn python off
I am even having problems with xcompile.sh. Looks like the manylinux build is working fine, but the android-arm64 is failing at this step:

Hmm… it should not be doing anything with Java…
Looks like I need to have $BUILD_JAVA rather than %BUILD_JAVA% in the xcompile.sh
See if changing that helps
