Performance Tips for Scalable Android Apps

⚙️ 1. Optimize Rendering and Layouts Use ConstraintLayout or Jetpack Compose with recomposition control to avoid unnecessary redraws. Avoid deep view hierarchies and expensive layout passes:

LazyColumn(state = scrollState) {
  items(items) { item ->
    Text(text = item.name)
  }
}        

Use Modifier.recomposeHighlighter() in Compose tooling to visualize overdraw.

📦 2. Efficient Image and Data Caching Use libraries like Glide, Coil, or Picasso with disk caching enabled. Cache JSON responses using Room or file storage. Avoid redundant API calls by leveraging ViewModel scopes and repository layers.

🔁 3. Background Work Best Practices Use WorkManager or CoroutineWorker for background sync, respecting battery constraints and network availability. Avoid blocking the UI thread with long operations.

🧪 4. Profiling and Monitoring Use Android Studio Profiler, LeakCanary, StrictMode, and Firebase Performance Monitoring to find memory leaks, frame drops, and expensive calls. Automate detection in CI using lint rules.

🧠 6. Final Tips:

• Use remember in Compose to prevent recomposition
• Debounce text inputs and search queries
• Prefer lazy loading (e.g., LazyColumn over Column)
• Keep main thread idle using async APIs
