I'm still going thru the videos and docs on Android. One thing that is an obvious potential issue is that glibc is not included. They created their own c library called libc and it is not compatible with glibc. That might put a damper on, or at least a slowdown, on the Squeak VM port to Android. I don't know if they have a tool that would illustrate the differences so that we could quickly find and fix functions.
