Display Bridge v0.2.0 — MVP

Display Bridge v0.2.0 — MVP

This is the first published MVP preview of Display Bridge for a Pixel phone and Rokid Glasses.

Highlights

• Universal Android presentation display over USB/AOA.
• Whole-screen mirroring after explicit Android consent.
• Hardware AVC encoding and decoding at up to 480×640 and 30 fps.
• Video-only transport: sound remains on the phone or its selected Bluetooth route.
• Low-latency bounded queues, adaptive bitrate, decoder feedback, and keyframe recovery.
• Material You phone UI and pure-black glasses UI.
• Configurable glasses gestures and Android media-key forwarding.
• Frame placement with preview, precise X/Y, favorites, and drag-and-drop sorting.
• First-frame wake, playback keep-awake, clean detach, and idempotent session switching.

Install

The two attached APKs are debug-signed MVP builds:

1. Install display-bridge-companion-v0.2.0-debug.apk on the phone owner profile.
2. Install display-bridge-glasses-v0.2.0-debug.apk on the glasses.
3. Open Display Bridge on the phone and connect the glasses by USB.

Known limitations

• External Display works only with Android applications that support presentation displays.
• Screen Mirror requires fresh MediaProjection consent for every session.
• Android may stop MediaProjection when the phone locks.
• Secure and DRM-protected content may render black.
• The APKs are debug-signed and intended for direct MVP testing, not store distribution.
• Remaining hardware acceptance is tracked in openspec/changes/ and docs/verification.md.
