@Simon-Kaz Thanks for the response. I run into a couple of issues using SikuliX:
Comparing (finding) images in two different screens usually fails, how do you deal with this kind of issue? Like maintain different images on captured different phones, or perhaps alternatives?
Which way do you use to make SikuliX communicate with phones? VNC solution on PC? From what I am understanding, if use VNC solutions, PC seems not available to work in parallel. I am researching if monkeyrunner on android platform can address the issue, but don't have clue yet. Basically, I want to use SikuliX for automating multiple games on multiple phones, very curious about how you solve these issue?
