# UI Modernization Tasks - Capture Mode

## Overview
This document outlines the planned modernization of the capture mode UI, transforming it from a basic floating button system to a modern, feature-rich interface.

## Implementation Journey & Current Status

### ✅ **What We Successfully Implemented**
- **Decoupled Architecture**: FloatingUIActivity + ScreenCaptureService with Binder communication
- **Material 3 Compose FAB**: Beautiful, animated FAB with proper Material Design
- **Expandable Menu**: Smooth animations, haptic feedback, proper Material 3 theming
- **Service Communication**: Clean Binder-based API for detection commands

### ❌ **Critical Issues Encountered**

#### 1. **Activity-Based Approach Issues**
- **Problem**: FloatingUIActivity not truly "floating" - positioned like regular activity
- **Symptom**: Couldn't drag freely, brought up navigation/status bars
- **User Feedback**: "It's not floating, I can drag it to the left a little but that's it"

#### 2. **ComposeView in Overlay Context**
- **Problem**: `ViewTreeLifecycleOwner not found` when using ComposeView in WindowManager overlay
- **Root Cause**: ComposeView requires LifecycleOwner, but overlay context has none
- **Attempts Made**:
  - Created custom `OverlayLifecycleOwner` implementing LifecycleOwner + SavedStateRegistryOwner
  - Tried `ViewTreeLifecycleOwner.set()` - API not available
  - Tried View.setTag() with lifecycle IDs - didn't work
  - Simplified approach without explicit lifecycle - still crashed

#### 3. **Transparency & System UI Issues**  
- **Problem**: Activity showed system bars, wasn't truly transparent
- **Symptoms**: Navigation bar visible, black status bar, couldn't see underlying apps
- **Attempts**: Immersive mode, SYSTEM_UI_FLAG_*, WindowInsetsController - partially worked

### 🔄 **Current Architecture State**

```
MainActivity → ScreenCaptureService → FloatingComposeOverlay (BROKEN)
                                   ↓
                              ComposeView + WindowManager (Crashes on lifecycle)
```

**Files Modified:**
- `FloatingUIActivity.kt` - Working Compose UI (but not truly floating)
- `FloatingComposeOverlay.kt` - Crashes due to lifecycle issues
- `ScreenCaptureService.kt` - Clean service communication
- `AndroidManifest.xml` - Activity registration with transparent theme

## Phase 1: Core Modernization ⚡

### 1.1 Material 3 Floating Action Button
**Priority: HIGH**  
**Status: PENDING**

Convert the current basic floating orb to a proper Material 3 FAB:
- Use Material 3 FAB component with proper elevation and shadows
- Smooth expand/collapse animations using AnimatedVisibility
- Material 3 color theming and dynamic colors
- Proper ripple effects and touch feedback
- Size variants (mini FAB for menu items)

**Technical Details:**
- Replace `Button` with `FloatingActionButton` in Jetpack Compose
- Implement `AnimatedVisibility` for menu expansion
- Use `Material3` theme colors and elevation tokens
- Add haptic feedback for interactions

### 1.2 Visual Design Modernization
**Priority: MEDIUM**  
**Status: PENDING**

- **Glass-morphism Effects**: Semi-transparent backgrounds with blur
- **Smooth Animations**: Choreographed transitions between states
- **Modern Icons**: Vector icons with proper scaling
- **Color Schemes**: Material You dynamic theming
- **Typography**: Material 3 typography scale

**Technical Details:**
- Implement blur effects using `Modifier.blur()`
- Custom animation specs for fluid motion
- Vector Drawable icons with animated state changes
- Dynamic color extraction from wallpaper (Android 12+)

## Phase 2: Enhanced Functionality 📊

FloatingActionButtonUI (Compose)
├── FABCore (Material 3 FAB)
├── ExpandableMenu (AnimatedVisibility)
├── DetectionOverlay (Canvas)
├── SettingsPanel (BottomSheet/Drawer)
└── StatusIndicators (Badges/Chips)
```

### Performance Considerations

**Sprint 2 (Week 3-4)**: Visual design modernization  
**Sprint 3 (Week 5-6)**: Detection results overlay
**Sprint 4 (Week 7-8)**: Enhanced UX patterns
**Sprint 5+ (Future)**: Advanced features as needed

## 🎯 Critical User Requirements (UPDATED)

### **Core Floating Behavior**
- ✅ **"Floating Action Button"** - Not basic Button, actual FAB with Material 3 design
- ✅ **"Truly floating"** - Like CalcIV, draggable anywhere on screen
- ✅ **"Not bringing up navigation bar"** - System UI completely hidden
- ✅ **"Show underlying apps"** - Transparent background, no window blocking content
- ❌ **"Blocky static developer UI"** - Must be polished, smooth, professional

### **🆕 NEW Requirements (Critical for Implementation)**
- 🎯 **"Soft dock to screen edges"** - When dragged within ~50px of left/right edge, animate to snap against edge
- 🎯 **"Touch-through for underlying apps"** - User must be able to interact with Pokemon GO UI:
  - Scroll through Pokemon lists
  - Tap buttons, menus, items
  - Pinch to zoom, swipe gestures
  - Only FAB itself should intercept touches, everywhere else passes through

### **Technical Implications of New Requirements**

#### **Edge Docking Implementation**
```kotlin
// Pseudo-code for edge snapping:
onDragEnd { finalPosition ->
    val screenWidth = getScreenWidth()
    val snapThreshold = 50.dp.toPx()
    
    val targetX = when {
        finalPosition.x < snapThreshold -> 0f // Snap to left edge
        finalPosition.x > screenWidth - snapThreshold -> screenWidth - fabWidth // Snap to right edge  
        else -> finalPosition.x // Stay where dropped
    }
    
    animateToPosition(targetX, finalPosition.y)
}
```

#### **Touch-Through Requirements**
This is the **most complex requirement** and changes our approach significantly:

**Option A Issues**: Activity approach likely won't work - Activities capture all touches within their bounds

**WindowManager Requirements**:
```kotlin
// Window must have precise touch handling:
WindowManager.LayoutParams(
    WRAP_CONTENT, WRAP_CONTENT, // Only FAB size, not fullscreen
    TYPE_APPLICATION_OVERLAY,
    FLAG_NOT_TOUCH_MODAL or  // Don't capture outside touches
    FLAG_LAYOUT_NO_LIMITS,   // Allow positioning anywhere
    PixelFormat.TRANSLUCENT
)

// FAB must be exactly positioned with minimal window size
// Everything outside FAB boundaries must pass through to underlying app
```

### **Revised Option Analysis**

#### **Option A: Activity Approach** - ⚠️ **PROBLEMATIC**
- **Major Issue**: Activities have window boundaries that may interfere with touch-through
- **Edge Docking**: Possible with window positioning
- **Touch-Through**: Very difficult - Activity windows tend to capture touches

#### **Option B: WindowManager + Views** - ⭐ **BEST FOR TOUCH-THROUGH**
- **Touch-Through**: Excellent - Window can be sized exactly to FAB dimensions
- **Edge Docking**: Perfect control with WindowManager.updateViewLayout()
- **Polish**: Need to ensure Material 3 styling with Views

#### **Option C: Advanced Compose** - ❓ **RESEARCH NEEDED**
- **Touch-Through**: Unknown if ComposeView can be made touch-through
- **Edge Docking**: Would work if lifecycle issues solved
- **Complexity**: High due to lifecycle issues

### **RECOMMENDED APPROACH: Option B Enhanced**
Given the new requirements, **WindowManager + Views** is now the clear winner:

1. **Precise Touch Handling**: Window sized exactly to FAB, everything else passes through
2. **Edge Snapping**: Full control over window positioning and animations  
3. **No Lifecycle Issues**: Views work perfectly in overlay context
4. **Material 3 Polish**: Use `com.google.android.material.floatingactionbutton.FloatingActionButton`

```kotlin
// Implementation approach:
class EnhancedFloatingFAB {
    // Material 3 FloatingActionButton with proper theming
    // ObjectAnimator for smooth edge snapping
    // WindowManager for precise positioning
    // Touch handling only within FAB bounds
}
```

## Success Metrics

- **Touch Behavior**: FAB interactive, underlying app fully usable
- **Edge Snapping**: Smooth 300ms animation to screen edges
- **Visual Polish**: Indistinguishable from Compose Material 3 FAB
- **Performance**: 60fps animations, no interference with underlying app

**UPDATED STATUS**: Option B (WindowManager + Material Views) now recommended due to touch-through requirements. Ready to implement enhanced version with edge snapping and precise touch handling.
