What happens when an android activity starts another activity

wasnt really sure what words to query in google, so im just going to ask this question.

What happens to an activity when i start another activity?

Lets say I am currently on activity A, then from a, i called a function to startService a new intent that opens activity B. What happens to the lifecycle of A? is it destroyed? stopped?

Subquestion. If the activity is paused, how do i call/open it back from the newly started activity?

Activity A is paused, then stopped - both the onPause() & onStop() methods are called, but onDestroy() is not called. The Activity still remains in the back stack.

Quoting the Android documentation:

Activity Lifecycle

Activities in the system are managed as an activity stack. When a new activity is started, it is placed on the top of the stack and becomes the running activity -- the previous activity always remains below it in the stack, and will not come to the foreground again until the new activity exits.
