Quick Start

What You Need

1. RayNeo X3 Pro AR glasses with USB debugging enabled
2. Sunshine installed on your PC (streaming host)
3. Your PC and glasses on the same WiFi network
4. ADB on your computer (download here)

Need help? Watch Informal Tech's video on how to sideload apps on the X3 Pro.

Install

1. Download RayDesk-v1.0.0.apk from the Releases page
2. Connect your glasses to your PC via USB
3. Install the APK:

   adb install RayDesk-v1.0.0.apk

4. Launch RayDesk from the glasses app drawer
5. Make sure your PC and glasses are on the same WiFi network
6. Your PC should appear automatically -- enter the pairing PIN shown on the glasses into the Sunshine web UI on your PC

ADB not detecting your glasses? The RayNeo X3 Pro sometimes requires the Zadig USB driver tool. Open Zadig, select your device, and install the WinUSB driver. Then retry adb devices. See the sideloading video for a step-by-step walkthrough.

Troubleshooting

If something goes wrong, capture a log and include it when filing an issue:

adb logcat -d -s Streaming:V *:E > raydesk-log.txt

Building from Source

Most users should download the pre-built APK from Releases. Building from source requires two proprietary dependencies:

Dependency	Source	Notes
Mercury SDK	Contact RayNeo for developer access	Place the AAR in a sdk/ directory
Moonlight Core	Build from moonlight-android + moonlight-common-c	Add as a :moonlight-core library module

# Requirements: JDK 17, Android SDK 34

# 1. Place Mercury SDK AAR in sdk/
# 2. Add moonlight-core as a library module
# 3. Uncomment the two dependency lines in app/build.gradle.kts
# 4. Add include(":moonlight-core") to settings.gradle.kts
# 5. Build:
./gradlew assembleDebug
