+
+**Status**: **FIXED** - All root causes identified and resolved.
+
+---
+
+## What Was Wrong
+
+### 1. Missing App Icon ❌ → ✅ FIXED
+- **Issue**: No launcher icon defined in the app
+- **Impact**: Widget couldn't register properly in Android system

+### 2. Missing Preview Image ❌ → ✅ FIXED  
+- **Issue**: No preview image configured for widget picker
+- **Impact**: Widget had no visual preview when browsing available widgets
+- **Fix**: Added preview image reference to widget configuration
