Android Studio

Core Rules

1. Check IDE Version First

Before suggesting features, confirm Android Studio version. Features vary significantly between Arctic Fox, Bumblebee, Flamingo, Hedgehog, and newer versions.

2. Platform-Aware Shortcuts

3. Use IDE Tools Over Manual Inspection

• Layout Inspector over print debugging for UI issues
• Profiler over manual timing for performance
• Database Inspector over manual queries
• Network Inspector over logging requests

4. Leverage Code Generation

• Live Templates for boilerplate (type abbreviation + Tab)
• File Templates for new components
• Generate menu (Cmd/Alt+N) for constructors, getters, overrides

5. Debugging Strategy

1. Breakpoints with conditions for targeted debugging
2. Evaluate Expression (Alt+F8) for runtime inspection
3. Watches for tracking variables across frames
4. Frame inspection to navigate call stack

Debugging Traps

• Setting breakpoints in hot loops → freezes IDE. Use conditional breakpoints.
• Debugging release builds → missing symbols. Debug with debug variant.
• Ignoring Logcat filters → drowning in logs. Filter by app package or tag.
• Not using "Attach Debugger" → missing app startup. Attach to running process.

Profiling Traps

• Profiling debug builds → misleading performance. Profile release builds.
• CPU Profiler without filtering → overwhelming data. Focus on specific methods.
• Memory Profiler heap dumps during GC → skewed results. Trigger GC first.
• Ignoring Network Profiler → missing slow API calls. Always check network timing.

Essential IDE Features

Layout Inspector

• Inspect live view hierarchy in running app
• 3D mode for seeing layer depth
• Attribute inspection for debugging constraints
• Works with Compose and View system

Database Inspector

• Query Room databases in real-time
• Edit values directly for testing
• Export data for analysis
• Requires API 26+ on device

Network Inspector

• Inspect OkHttp/Retrofit requests without code changes
• View request/response bodies
• Timeline for identifying slow calls
• Requires enabling in manifest for release

App Inspection

• Combined view of Database, Network, Background Tasks
• WorkManager task monitoring
• Background task scheduling inspection

Refactoring Shortcuts

Build Configuration

Gradle Sync Issues

• File → Invalidate Caches / Restart for persistent issues
• Delete .gradle and .idea folders as last resort
• Check Gradle JDK in Preferences → Build → Gradle

Build Variants

• Select variant in Build Variants panel
• Debug vs Release affects debugging capabilities
• Product flavors for different app configurations

SDK Manager

• Tools → SDK Manager for Android SDK updates
• Install platform tools matching target devices
• Keep build tools updated for latest features

Emulator Tips

• Cold Boot vs Quick Boot: use Quick Boot for speed
• Extended Controls (three dots) for sensors, location, battery
• Snapshots for saving specific device states
• Device mirroring for physical device control
