Android Performance Standards

Priority: P1 (HIGH)

1. Accelerate Startup

  • Generate Baseline Profiles for all production apps — pre-compiles critical paths (30-40% startup improvement).
  • Defer heavy SDK init using App Startup or lazy Singletons. Never block Application.onCreate.

See baseline & startup for lazy initialization patterns.

2. Eliminate UI Jank

  • Use Layout Inspector to find unnecessary recompositions.
  • Load images with Coil/Glide using proper caching and resizing (.crossfade()).
  • LazyColumn must use key and stable item classes.

See baseline & startup for LazyColumn optimization.

3. Avoid Layout Bottlenecks

  • Replace nested weights with ConstraintLayout (Views) or Row/Column with Modifier.weight (Compose).
  • Never hold Activity context in Singletons — use Application context to prevent memory leaks.

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.
