AI-Powered Extension Generator for Visual Android Development

This video showcases an intelligent solution that uses artificial intelligence to simplify and speed up the creation of custom extensions for visual Android app development environments.

Through natural language interaction, the system understands project structures, components, and logic, then automatically generates Java-based extensions tailored to specific needs. It can analyze uploaded project files, interpret schemas, and propose multiple optimized extension alternatives for the developer to choose from.

Key features:

  • Conversational creation of extensions
  • Automatic analysis of components and properties
  • Generation of multiple extension ideas and implementations
  • Scalable, clean, and professional architecture
  • Ideal for learning, teaching, and real-world app development

This approach removes technical barriers and empowers creators to extend visual apps with advanced native features, combining simplicity with professional-grade results.

Watch the video and discover how AI can elevate visual Android development to the next level.

Probably we should wait for the author @JEWEL to publish this himself?
The better category probably would be Extension Development. I now moved it there.

Our focus should also extend to the code editor, enabling users to navigate to and modify source code. Integrating a code suggestion feature would be beneficial if feasible.

Additionally, we must carefully consider our strategy for managing the premium features of FAST-CLI.

Why do we need to upload an aia file?

This upload is to generate an extension for custom component beautification. If you want to generate a custom extension, I suggest using the chatbot.

Could you please provide instructions on how to create, navigate, and modify these files?
Additionally, it would be beneficial if we could create and modify sources even if they are not directly associated with the base package name.

AI Code Generation Improvements

  • Automatic Code Organization: AI now automatically creates multiple files when needed - helper classes, enums, and separate extensions appear organized in the directory tree
  • Enums with @Options: Automatic creation of Enums annotated with @Options for parameters accepting selectable values (like colors, modes, shapes)
  • Smart Modularization: Code over 50 lines is automatically separated into helper classes for better maintainability
  • Multiple Extensions: Complex projects (200+ lines or independent features) are divided into separate extensions

File Management

  • IDE-Style File Explorer: IDE-like interface with folder tree to manage multi-file projects
  • Library Upload: Support for manual .jar and .aar file uploads in the "Libs" tab
  • Manual File Creation: Add new Java, XML, or resource files directly in the explorer

Compilation

  • Automatic Fast Sync: Automatic download of remote dependencies before compilation
  • Headless Mode: Java compilation optimized for server environment

Interface

  • Monaco Editor (VS Code): Professional editor with syntax highlighting and Java autocomplete
  • Voice Input: Voice support to describe your extension
  • Configurable Font Size: Adjust chat font size in settings

Project Backup System

  • Save manual backups of your project at any time
  • History stores up to 10 backups locally in your browser
  • Automatic backup created before each compilation
  • Restore any previous version with one click
  • Each backup preserves all files, Java code, configurations, and helpers

Extension Icon Upload

  • Upload PNG/JPG icons directly in the "Options" tab
  • The fast.yml file is automatically updated with the assets: section
  • All Java extensions are updated with iconName = "your_icon.png"
  • Icon preview with option to remove
  • Icon automatically included in compilation

AI Chatbot Improvements

  • File autocomplete with "/" - type "/" in the chat to select specific files
  • AI preserves existing files - helpers and extensions are never auto-deleted
  • Intelligent merge system - updates files by name, adds new ones, preserves unmodified
  • Analysis/verification responses don't modify your code

I believe it would be beneficial to allow users to navigate their entire projects. This would enable them to upload any assets they wish and edit them as they deem appropriate. Additionally, they could upload local dependencies to the 'deps' directory, and all sources could be modified from the 'src' directory, providing an experience similar to a local explorer.

File Explorer Enhancements

  • Resizable file tree - Users can now drag the right edge to resize the file explorer width (200-600px range)
  • Individual file download - Ultimate users and admins can download any file via the three-dot context menu

Code & Options Tab

  • Removed redundant icon upload - The separate icon upload section was removed since images can now be uploaded directly to the assets folder in the file tree

Bug Fixes

  • Fixed config files disappearing - Configuration files (fast.yml, README.md, AndroidManifest.xml, proguard-rules.pro) were intermittently disappearing from the file tree; this has been resolved by properly preserving existing config files during state updates
