Overview
An Android RDP server experiment that explores how far a normal installed app can go toward exposing the Android screen over RDP without relying on ADB as the runtime architecture. Built in Kotlin with a Go core via gomobile, reusing the go-rdp protocol stack for the RDP wire format. Screen capture uses MediaProjection; input injection uses the Accessibility Service API.
How it works
The Kotlin app hosts a foreground service that acquires a MediaProjection virtual display for screen capture. Frames are handed to the Go RDP encoder (linked via gomobile) which handles the RDP protocol, bitmap compression, and client sessions. Input events from RDP clients are translated into Android accessibility actions — taps, swipes, and key presses — through a bound AccessibilityService. No root, no ADB tunnel required.
Features
No ADB required
Runs as a normal installed Android app — no root, no developer mode, no USB tunnel.
go-rdp core
Reuses go-rdp's protocol stack via gomobile — RDP encoding, session management, bitmap compression.
MediaProjection capture
System-level screen capture through Android's MediaProjection API.
Accessibility input injection
RDP mouse/keyboard events translated to Android taps, swipes, and keys via AccessibilityService.
Desktop mock server
Includes a standalone Go mock for testing RDP clients without an Android device.
