System Performance

Optimizing for speed and efficiency

Why Performance Matters?

Performance is a key factor in user satisfaction. A smooth, responsive app retains users, while a laggy one drives them away. Android provides tools to measure and improve performance.

Vital Performance Metrics

Frame Rate

Consistent 60fps (or 90/120fps) rendering for smooth UI.

App Startup Time

Cold, warm, and hot start times.

Memory Usage

Avoid leaks and excessive memory footprint.

Battery Drain

Minimize background work and wake locks.

Network Usage

Optimize data transfer and API calls.

ANR (App Not Responding)

Application Not Responding errors.

Optimization Best Practices

  • Use RecyclerView for large lists.
  • Offload work to background threads (Coroutines, WorkManager).
  • Profile your app using Android Studio's Profiler.
  • Reduce overdraw in your layouts.
