# Landscape Only Mode

App configured to run exclusively in landscape orientation.

## AndroidManifest.xml Configuration

```xml
<uses-feature android:name="android.hardware.screen.landscape" android:required="true" />

<activity
    android:name=".MainActivity"
    android:screenOrientation="landscape"
    android:configChanges="orientation|screenSize">
</activity>
```

All activities (MainActivity, EstrategemasActivity, QRActivity) have:
- `android:screenOrientation="landscape"` - Forces landscape
- `android:configChanges="orientation|screenSize"` - Prevents activity recreation

## Code Changes Required

### Removed from all Activities:
- `onConfigurationChanged()` method - no longer needed
- Portrait-specific constants and logic
- Layout switching logic (portrait vs landscape)

### QRActivity Specific:
```java
// OLD: Size based on orientation
int qrSize = (orientation == LANDSCAPE) ? QR_SIZE_LANDSCAPE : QR_SIZE_PORTRAIT;

// NEW: Fixed landscape size
private static final int QR_SIZE = 360;  // 180dp x 2 for xhdpi
```

## Layout Structure

Only `res/layout/` exists - no `layout-land/` subdirectory needed.
All layouts are designed specifically for landscape (720x1280 on Galaxy S3).

## Benefits for Galaxy S3:

1. **Memory savings** - No duplicate layouts in memory
2. **Simpler code** - No orientation change handling
3. **Consistent UI** - Always optimized for 4.8" landscape display
4. **Better game experience** - Estrategemas minigame designed for wide screen

**Why:** User requested fixed landscape for consistent Helldivers 2 theme experience. Removes complexity of handling rotation on low-memory devices.

**How to apply:** When creating new activities, always add `android:screenOrientation="landscape"`. Never implement onConfigurationChanged(). Single layout folder only.
