Android Performance Standards

Priority: P1

Implementation Guidelines

Startup Time

  • Baseline Profiles: Mandatory for all production apps to pre-compile critical paths (improves startup by 30-40%).
  • Lazy Initialization: Defer heavy SDK init using App Startup or lazy Singletons. Avoid blocking Application.onCreate.

UI Performance

  • Recomposition: Use "Layout Inspector" to find unnecessary recompositions.
  • Images: Use Coil/Glide with proper caching and resizing (.crossfade()).
  • Lists: LazyColumn must use key and stableitem classes.

Anti-Patterns

  • No Nested Weights: Use ConstraintLayout (Views) or Row/Column (Compose) instead.
  • No Activity Context in Singletons: Use Application context to prevent memory leaks.
