Your question is Android App Performance Optimization. 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).
Explain how you would optimize an Android app for performance. Focus on how you would identify bottlenecks, reduce UI jank, lower memory pressure, and improve code-level efficiency using better data structures or algorithms.
