# 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](references/implementation.md) 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](references/implementation.md) 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.
