+name: Landscape Only Mode
+description: Fixed landscape orientation for all activities - no rotation handling needed
+type: project
+---
+
+# 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.
