What problem does it solve?

Android Performance Profiler helps developers identify and fix performance bottlenecks in Android apps, including UI jank, memory leaks, slow startup, excessive battery usage, and inefficient Compose recomposition.

Core Features & Use Cases

• Profiling tools: Android Studio Profiler and Macrobenchmark to measure CPU, memory, startup, and frame timings.
• Performance patterns: Techniques to improve UI responsiveness, memory management, startup times, battery efficiency, and Compose optimization.
• Use Case: Assess a slow-scrolling screen and derive concrete optimizations to reduce frame drops and memory churn.

Quick Start

Identify performance issue type:

1. UI Jank / Frame Drops
2. Memory Leaks
3. Slow Startup
4. High Battery Drain
5. Database Slowness
6. Compose Recomposition
7. Network Performance

Profiling workflow:

• Enable profiling on a device or emulator with the app built in debuggable mode.
• Use Android Studio Profiler to capture CPU, memory, and energy metrics.
• Run macrobenchmark tests for startup and frame timings.
• Analyze results and apply targeted optimizations.

Operational tips:

• Maintain stable data classes with @Immutable.
• Offload heavy work from the main thread.
• Use proper caching and lazy loading.
