I'll fix these video extraction issues and improve the service to automatically fetch video information. Let me update the video extraction service and related components.

Key Improvements Made:

Fixed Video Extraction Issues

• Updated Instagram extraction - Better handling of current Instagram structure
• Fixed TikTok extraction - Improved URL parsing and oEmbed usage
• Enhanced Twitter/X support - Handles both twitter.com and x.com URLs
• Better error handling - More descriptive error messages

Improved Download Functionality

• Fixed permission handling - Better iOS/Android permission management
• Simulated downloads - Works in Expo Go with mock files
• Better error messages - Clear feedback about Expo Go limitations

Enhanced User Experience

• Auto-fetch video info - Automatically fetches info when valid URL is pasted
• Real-time validation - Shows URL validation errors immediately
• Better loading states - Clear feedback during info fetching
• Improved UI feedback - Better error messages and success notifications

Platform-Specific Fixes

• YouTube - Uses oEmbed API for reliable info extraction
• Instagram - Multiple fallback approaches for different URL types
• TikTok - Handles shortened URLs and different formats
• Twitter/X - Updated for X rebrand and current API structure
• Facebook - Better HTML parsing for video detection
• Dailymotion - Uses official oEmbed API

Demo Mode Features

• Mock downloads - Creates demo files that work in Expo Go
• Progress simulation - Shows realistic download progress
• Clear notifications - Explains Expo Go limitations to users

The app now:

1. Automatically fetches video info when you paste a URL
2. Handles all major platforms with improved extraction
3. Works in Expo Go with simulated downloads
4. Provides clear feedback about what's happening
5. Validates URLs in real-time and shows helpful errors

For production use, you'd replace the mock download functionality with real video download libraries like yt-dlp or similar services.

You're right! The current implementation has several issues with the download simulation and progress tracking. Let me fix these problems:

Fixed Issues:

1. Progress Tracking Sync

• Fixed progress bar synchronization between download screen and Redux store
• Added proper progress updates with realistic timing
• Progress now shows actual percentage during download

2. File Creation & Location

• Creates actual demo files in app directory with proper content
• Shows exact file path after download
• Added "View App Directory" button to see all downloaded files
• Files now have proper naming with timestamps

3. Download Simulation

• Realistic download progress with variable timing
• Proper file creation with detailed content
• Cancel download functionality
• Better error handling and user feedback

4. User Experience Improvements

• Clear success messages with file location
• Button to view app directory and list files
• Disabled UI elements during download
• Cancel download option
• Better progress visualization

5. Expo Go Limitations Explained

• Clear messaging about Expo Go limitations
• Explains why files aren't in gallery
• Shows where files are actually saved
• Guidance for development build

Why Files Aren't in Gallery (Expo Go):

1. Expo Go Sandbox: Expo Go runs in a sandboxed environment
2. Limited Permissions: Cannot save to device gallery/photos
3. Demo Files: Creates text files (not actual videos) for demonstration
4. App Directory Only: Files saved to app's document directory

To Get Real Downloads:

1. Create Development Build: npx create-expo-app --template
2. Add Real Download Logic: Implement actual video download services
3. Proper Permissions: Request full media library permissions
4. Real Video Files: Download actual video files instead of demo text

The app now properly shows download progress, creates demo files, and clearly explains the limitations!
