barayefarda/-livdub-app ? reverse-engineered prompt

I want you to build an Android app called Livdub that can dub the sound playing on my phone in real time. It should work with audio from other apps like YouTube, Instagram, Telegram, browsers, and podcasts, without using the microphone, and it should feel native and modern with a clean Compose UI.

The app needs a floating bubble that stays on top of other apps, so I can start and stop dubbing with one tap while something is playing. It should capture internal audio, send short audio chunks to Gemini 2.0 Live API over a live connection, and play the translated dub back immediately with very low delay. Please make it work smoothly on Android 10 and up, and include a simple place for me to enter my API key and get started easily. If you need to check current Android or Gemini docs while building it, go ahead.
