# 🔔 Comprehensive Notification Integration - Implementation Summary

## ✅ **What Was Implemented**

I've successfully integrated notifications with your library and Trakt system, adding automatic background notifications for all saved shows. Here's what's now working:

---

## 🚀 **1. Library Auto-Integration**

### **Automatic Notification Setup**
- **When adding series to library**: Notifications are automatically scheduled for upcoming episodes
- **When removing series from library**: All related notifications are automatically cancelled
- **Real-time sync**: Changes to library immediately trigger notification updates

### **Implementation Details:**
```typescript
// In catalogService.ts - Auto-setup when adding to library
public async addToLibrary(content: StreamingContent): Promise<void> {
  // ... existing code ...
  
  // Auto-setup notifications for series when added to library
  if (content.type === 'series') {
    await notificationService.updateNotificationsForSeries(content.id);
  }
}
```

## 🎬 **2. Trakt Integration**

### **Comprehensive Trakt Support**
- **Trakt Watchlist**: Automatically syncs notifications for shows in your Trakt watchlist
- **Trakt Collection**: Syncs notifications for shows in your Trakt collection
- **Background Sync**: Periodically checks Trakt for new shows and updates notifications
- **Authentication Handling**: Automatically detects when Trakt is connected/disconnected

### **What Gets Synced:**
- All series from your Trakt watchlist
- All series from your Trakt collection
- Automatic deduplication with local library
- IMDB ID mapping for accurate show identification

---

## ⏰ **3. Background Notifications**

### **Automatic Background Processing**
- **6-hour sync cycle**: Automatically syncs all notifications every 6 hours
- **App foreground sync**: Syncs when app comes to foreground
- **Library change sync**: Immediate sync when library changes
- **Trakt change detection**: Syncs when Trakt data changes

### **Smart Episode Detection:**
- **4-week window**: Finds episodes airing in the next 4 weeks
- **Multiple data sources**: Uses Stremio first, falls back to TMDB
- **Duplicate prevention**: Won't schedule same episode twice
- **Automatic cleanup**: Removes old/expired notifications

---

## 📱 **4. Enhanced Settings Screen**

### **New Features Added:**
- **Notification Stats Display**: Shows upcoming, this week, and total notifications
- **Manual Sync Button**: "Sync Library & Trakt" button for immediate sync
- **Real-time Stats**: Stats update automatically after sync
- **Visual Feedback**: Loading states and success messages

### **Stats Dashboard:**
```
📅 Upcoming: 12    📆 This Week: 3    🔔 Total: 15
```

---

## 🔧 **5. Technical Implementation**

### **Enhanced NotificationService Features:**

#### **Library Integration:**
```typescript
private setupLibraryIntegration(): void {
  // Subscribe to library updates from catalog service
  this.librarySubscription = catalogService.subscribeToLibraryUpdates(async (libraryItems) => {
    await this.syncNotificationsForLibrary(libraryItems);
  });
}
```

#### **Trakt Integration:**
```typescript
private async syncTraktNotifications(): Promise<void> {
  // Get Trakt watchlist and collection shows
  const [watchlistShows, collectionShows] = await Promise.all([
    traktService.getWatchlistShows(),
    traktService.getCollectionShows()
  ]);
  // Sync notifications for each show
}
```

#### **Background Sync:**
```typescript
private setupBackgroundSync(): void {
  // Sync notifications every 6 hours
  this.backgroundSyncInterval = setInterval(async () => {
    await this.performBackgroundSync();
  }, 6 * 60 * 60 * 1000);
}
```

---

## 📊 **6. Data Sources & Fallbacks**

### **Multi-Source Episode Detection:**
1. **Primary**: Stremio addon metadata
2. **Fallback**: TMDB API for episode air dates
3. **Smart Mapping**: Handles both IMDB IDs and TMDB IDs
4. **Season Detection**: Checks current and upcoming seasons

### **Notification Content:**
```
Title: "New Episode: Breaking Bad"
Body: "S5:E14 - Ozymandias is airing soon!"
Data: { seriesId: "tt0903747", episodeId: "..." }
```

---

## 🎯 **7. User Experience Improvements**

### **Seamless Integration:**
- **Zero manual setup**: Works automatically when you add shows
- **Cross-platform sync**: Trakt integration keeps notifications in sync across devices
- **Smart timing**: Respects user's preferred notification timing (1h, 6h, 12h, 24h)
- **Battery optimized**: Efficient background processing

### **Visual Feedback:**
- **Stats dashboard**: See exactly how many notifications are scheduled
- **Sync status**: Clear feedback when syncing completes
- **Error handling**: Graceful handling of API failures
