OllamaVerse features an advanced file caching system that dramatically improves performance by eliminating redundant file processing operations.

The system creates unique cache signatures for each file using SHA-256 hashing based on:

• File path and name
• File size
• Last modification timestamp

When you upload a file that's been processed before, the system instantly retrieves the cached content instead of re-processing it from scratch.

• 99% Speed Improvement: Previously processed files load in under 50ms instead of several seconds
• Resource Efficiency: 50-90% reduction in CPU usage for repeated file operations
• Seamless Experience: Zero waiting time for cached files in multi-turn conversations
• Batch Optimization: Multiple file uploads are intelligently optimized with cache detection

• Automatic Size Control: 200MB cache limit with Least Recently Used (LRU) eviction
• Data Freshness: 30-day automatic expiration ensures up-to-date content
• File Change Detection: Cache automatically invalidates when source files are modified
• Error Resilience: System gracefully falls back to processing if cache fails

• Real-time Statistics: Monitor cache size and entry count in Settings
• Manual Cache Clearing: Clear cache instantly with immediate UI feedback
• Transparent Operation: Works seamlessly behind the scenes with no user intervention required
• Storage Integration: Cache management integrated with existing cleanup system

This caching system is particularly beneficial for Ollama workflows involving:

• Document Analysis: Instantly re-analyze PDFs, research papers, or reports across multiple chats
• Code Review: Rapidly iterate on code files without processing delays
• Image Processing: Immediate access to previously uploaded images for vision models
• Multi-session Workflows: Same files available instantly across different conversations

• Unified Operation Tracking: New isAnyOperationInProgress getter tracks all types of operations (generation, file processing, sending)
• Comprehensive Cancellation: Stop button now properly cancels all operations including file processing
• Proper State Reset: Cancellation correctly resets all operation flags and clears any ongoing streams
• Persistent State Fix: Prevents stop button state from persisting when switching/deleting chats during operations
• Smart Button Logic: Button dynamically switches between send and stop modes based on any ongoing operation
• Immediate Response: Stop button provides immediate feedback and cancellation without delays

If you're experiencing connection issues on Android when trying to connect to a remote Ollama instance:

1. "Connection Failed" or "Connection timed out" errors:

   • Check Network Connectivity: Ensure your Android device is connected to the same network as your Ollama server
   • Verify Server Address: Make sure you're using the correct IP address and port (not localhost or 127.0.0.1 when connecting remotely)
   • Test Server Accessibility: Try accessing http://YOUR_SERVER_IP:11434/api/tags in a web browser on your Android device

2. Firewall and Network Configuration:

   • Server Firewall: Ensure your Ollama server's firewall allows connections on port 11434
   • Router/Network Firewall: Check if your router or network firewall is blocking the connection
   • Ollama Binding: Make sure Ollama is bound to 0.0.0.0:11434 (not just 127.0.0.1:11434)

3. Android-Specific Network Issues:

   • Clear DNS Cache: Go to Android Settings > Apps > OllamaVerse > Storage > Clear Cache
   • Network Security: The app is configured to allow HTTP connections for development
   • Mobile Data vs WiFi: Try switching between mobile data and WiFi to isolate network issues

To allow remote connections to your Ollama server:

1. Set Environment Variable (recommended):

   export OLLAMA_HOST=0.0.0.0:11434
   ollama serve

2. Or start with host binding:

   ollama serve --host 0.0.0.0:11434

3. For systemd services, edit the service file:

   sudo systemctl edit ollama

   Add:

   [Service]
   Environment="OLLAMA_HOST=0.0.0.0:11434"

1. From your computer: curl http://YOUR_SERVER_IP:11434/api/tags
2. From Android browser: Navigate to http://YOUR_SERVER_IP:11434/api/tags
3. In the app: Go to Settings and use "Test Connection"

• Local network: 192.168.1.100:11434
• Docker: Ensure port mapping -p 11434:11434
• Cloud server: Use public IP and ensure security groups/firewall rules allow port 11434

If issues persist, check the app logs in Settings > About for detailed error messages.
