No serial library Processing for smartphone. Help

I apologize to everyone present, if I cannot answer immediately, with a delay, and also do not immediately try the code, this is not disrespect towards those present. I am constantly on the road or at work, I answer immediately when there is an opportunity. And to try the code, I need even more time, I am an electrical engineer, not a professional programmer. This topic and the solution to this issue are very important to me. I am very grateful to everyone who helps and participates in finding a solution.
thank_you
