flyun/chatAir ? reverse-engineered prompt

Build me a native Android app for chatting with AI models like ChatGPT, Gemini, Claude, and DeepSeek. I want it to feel fast and smooth, with a clean chat interface, support for Markdown and code highlighting, and a nice dark mode with a few theme options.

Please include the ability to sign in or configure API settings, switch between models, change temperature, reply length, and history settings, and also let me use custom server addresses like OpenRouter, One API, or Ollama if needed. I’d also like image recognition so I can send a picture and get it analyzed.

Make it support multiple languages, including English and Chinese, and keep the whole thing polished enough for daily use. If you need to look up current docs online to make sure the integrations are done right, go ahead and do that.
