Multiple Services and Main_Thread communicating Kotlin

Question

Converting code from iOS Swift to Android Kotlin has not been fun for this old dinosaur mainframe Fortran guy.

I’ve learned about Services, foreground and others, Coroutines and channels, Broadcast Receivers, Run blocking, etc. I’ve got samples running for many different techniques and designs. I’ve learned a lot; and have merged a lot in my app.

I’m running into most difficulties in getting the pieces talking to each other and even debugging what I’m trying.

I’ve learned so much on this site by searching specific questions. I’ve learned things not to do on this subject, like not more than one foreground service, avoid threads, etc. So I thought this time I would start high level and not specific how to’s.

Your help in best way, as title states ... What do you have to offer to allow me to accomplish in Kotlin.. “Multiple Services and Main_Thread communicating” Tips, caution, and understanding I’m an old dog learning new tricks, will be greatly appreciated.
