I’m a little confused by the difference between Java and Android Java. Let’s say I have an Activity class AndroidX. There is no main function and there is no AndroidX() constructor as we know it. I realize that onCreate() most probably initializes the AndroidX Activity, but why is there no main? What’s the difference?
This graphic may help some.

In the Activity documentation they elaborate on what each function is meant for (i.e. onCreate(), onResume(), etc).
