Activity side-by-side lifecycle

Imagine that I have an Activity A and I'm starting a new activity B from that one.

What will be the Activities lifecycle side-by-side?

 1. A: onCreate 
 2. A: onStart 
 3. A: onResume

on A => startActivity(B)

 4. B: onCreate
 5. B: onStart

 6. A: onPause

 7. B: onResume

 8. A: onStop

Is this correct?

Solution

  • Almost correct, just a minor difference. first A.onPause() and then B.onCreate()... etc

    A: onCreate
A: onStart
A: onResume

    on A => startActivity(B)

    A: onPause
B: onCreate
B: onStart
B: onResume
A: onStop
