```

### Creating Debug Build

```bash
# Export unsigned debug APK
# Install via ADB
adb install builds/android/YourGame-debug.apk

# Run and view logs
adb logcat | grep YourGame
```

### Creating Release Build

**1. Create Release Keystore:**
```bash
keytool -genkey -v -keystore release.keystore -alias my_game_key \
  -keyalg RSA -keysize 2048 -validity 10000

# Keep this keystore safe! You need it for all future updates
```

# List devices
adb devices

# Install
adb install YourGame.apk

# Uninstall
adb uninstall com.yourcompany.yourgame

# View logs
adb logcat -c  # Clear logs
adb logcat | grep YourGame
```

### Android Distribution

**Google Play Store:**
```
1. Create Play Console account
2. Create app listing
3. Upload AAB (not APK)

5. Set pricing
6. Submit for review
```

**Other Stores:**

- Direct download (APK)

### Android Optimization

**Reduce APK Size:**
```
# In export preset:
- Enable compression
- Disable unused ABIs
- Compress textures (ASTC)
- Remove unused resources
- Use ProGuard/R8
```

**Performance:**
```gdscript
# Target 60 FPS on mid-range devices
# Test on:
# - Low-end device (2GB RAM)
# - Mid-range device (4GB RAM)
# - High-end device (8GB+ RAM)

# Android-specific optimizations:
func _ready():
    if OS.get_name() == "Android":
        # Reduce particle count
        # Lower shadow quality
        # Disable post-processing effects
        pass
```

---

## Multi-Platform Tips

### Asset Optimization

**Textures:**
```
Desktop: PNG, JPEG, or uncompressed
Web: Compress, reduce resolution
Mobile: ASTC compression, aggressive optimization
```

**Audio:**
```
Music: OGG Vorbis, 128kbps
SFX: OGG Vorbis, 64kbps
Mobile: Lower bitrates
```

**3D Models:**
```
Desktop: Full detail
Web: Reduce poly count 30%
Mobile: Reduce poly count 50%
```

### Platform Detection

```gdscript
extends Node

func _ready():
    match OS.get_name():
        "Windows":
            setup_windows()
        "Linux", "FreeBSD", "NetBSD", "OpenBSD", "BSD":
            setup_linux()
        "macOS":
            setup_macos()
        "Web":
            setup_web()
        "Android":
            setup_android()
        "iOS":
            setup_ios()

func setup_windows():
    # Windows-specific setup
    DisplayServer.window_set_vsync_mode(DisplayServer.VSYNC_ENABLED)

func setup_mobile():
    # Touch controls, battery optimization
    if OS.get_name() in ["Android", "iOS"]:
        # Mobile optimizations
        pass
```

### Feature Flags

```gdscript
const FEATURES = {
    "cloud_saves": true,
    "multiplayer": true,
    "analytics": true,
    "haptics": OS.get_name() in ["Android", "iOS"],
    "keyboard": OS.get_name() not in ["Android", "iOS", "Web"],
}

func _ready():
    if FEATURES.cloud_saves:
        await AeThexCloud.connect_to_cloud()
```

---

## Troubleshooting

### Common Issues

**Export template missing:**
```
Solution: Download export templates from
Editor → Export Templates → Download
```

**Code signing failed (macOS):**
```bash
# Verify certificate
security find-identity -v -p codesigning

# Check entitlements
codesign -d --entitlements :- YourGame.app
```

**Web build doesn't load:**
```
Check console for errors
Must be served from HTTP server (not file://)
Check SharedArrayBuffer requirements
Enable CORS headers if needed
```

**Android build fails:**
```bash
# Check SDK paths
echo $ANDROID_HOME

# Update build tools
sdkmanager --update

# Clean build
./gradlew clean
```

### Performance Testing

```gdscript
# Add FPS counter
func _process(delta):
    if OS.is_debug_build():
        $FPSLabel.text = "FPS: " + str(Engine.get_frames_per_second())
```

### Build Size Optimization

```
1. Disable unused modules in export preset
2. Compress textures appropriately
3. Use streaming for large assets
4. Remove debug symbols (release mode)
5. Use platform-specific compression
```

---

## Best Practices

### Before Every Release

✓ Test on all target platforms  
✓ Profile performance  
✓ Check memory usage  
✓ Test on low-end hardware  
✓ Verify all assets load correctly  
✓ Test input methods (keyboard, gamepad, touch)  
✓ Check for crash logs  

### Versioning

```
Use semantic versioning: MAJOR.MINOR.PATCH
Example: 1.2.3

MAJOR: Breaking changes
MINOR: New features (backward compatible)
PATCH: Bug fixes

Android version code: Increment for each release
```

### Continuous Integration

```yaml
# GitHub Actions example
name: Export Game
on: [push]

jobs:
  export:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Export for Windows
        run: |
          # Export commands here          
      - name: Upload artifacts
        uses: actions/upload-artifact@v2
        with:
          name: game-builds
          path: builds/
```
