Landscape Only Mode	Fixed landscape orientation for all activities - no rotation handling needed	project

Landscape Only Mode

App configured to run exclusively in landscape orientation.

AndroidManifest.xml Configuration

<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:

// 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.
