Your question is Timer Continues After App Close. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you handle the timer continuing to run even if the user closes the app?
Design an Android implementation that remains correct when the process is killed and the user later reopens the app. Explain the architecture, state ownership, persistence, background scheduling, UI updates, and how you would test time-based behavior.
