Skillshub android-performance

Standards for Baseline Profiles, Startup Time, and UI Rendering. Use when optimizing app startup, jank, or UI rendering performance in Android. (triggers: **/*Benchmark.kt, **/*Initializer.kt, BaselineProfile, JankStats, recomposition)

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.
