Android Launch Cycle Anatomy

Question

I cannot find documentation on the details of the Activity launch cycle for Android.

Apple is documenting the “ anatomy of the launch cycle, ” and that is pretty much what I'm looking for. The Android documentation just says “ “ Activity works ”) in the life cycle status diagram. Obviously, the backup is done by some kind of startup cycle.

Does anyone have aka Documentation in the inner cycles of an action loop?

edit - I have to clarify that I assume that the execution loop is actually owned and controlled by the main user interface thread. The current activity function is likely to be introduced into this runloop at some point. I am interested in the full execution cycle of the user interface thread, and also what role activity takes in it.
