LinkBridge

A lightweight, offline, local-WiFi-only link/text bridge between an Android Phone and an Android TV. No Google services, no cloud, no accounts — just your local network.

How It Works

1. TV App runs an HTTP server on port 9090 and listens for incoming links.
2. Phone App registers as a "Share" target. Select any text/link → Share → LinkBridge → sends it to the TV.
3. TV receives the link, saves it to history, and automatically opens the "Open With" dialog.
4. Discovery: The phone can auto-discover TVs on the same WiFi network via UDP broadcast.
