AiixiBear/media_control ? reverse-engineered prompt

I want you to build an Android app in Traditional Chinese that can act like a local media remote for my phone.

The app should let me open a web page from another device on the same Wi Fi network and see what is currently playing on the phone, including the app name, artist, album, progress, and play state. From that page I should be able to play, pause, skip to next or previous track, and scrub forward or backward. It should update automatically while the page is open.

Please also add a simple REST API that works in a Home Assistant style, so I can get the media player state and send control commands programmatically. The app needs to work on Android and ask for notification access so it can find active media sessions. Make the interface clean and easy to use, and keep the main language in Traditional Chinese. If you need to check current Flutter or Android docs while building it, go ahead and look them up online.
