Display Bridge v0.3.2 — Wi-Fi Direct coexistence hotfix

Fixes Wi-Fi Direct coexistence with Hi Rokid and other applications.

• Never adopts or removes a Wi-Fi Direct group before Display Bridge ownership is verified.
• Leaves pre-existing Wi-Fi Direct sessions untouched instead of resetting them.
• Verifies the DNS-SD-discovered phone before the glasses accept a group.
• Uses non-persistent Display Bridge groups on Android 10 and newer.

Both APKs are signed production release builds.

Display Bridge v0.3.1 — Wired selection hotfix

Display Bridge v0.3.1

Wired connection selection hotfix.

Fixed

• Selecting Wired and pressing Connect no longer switches the Connection control back to Wireless because of a stale wireless transport snapshot.
• Wired Connect now explicitly stops Wi-Fi Direct and wireless recovery, clears stale wireless state, and starts a USB/AOA connection attempt.
• Restored USB auto-connect-on-attach after switching back from Wireless without performing a duplicate immediate USB scan.

The Glasses APK has no behavioral changes in this hotfix; its version was advanced to 0.3.1 (7) so both release artifacts remain aligned.

Both APKs use the existing Display Bridge release certificate and update in place from v0.3.0.

Display Bridge v0.3.0 — Wireless mode

Display Bridge v0.3.0

Wireless display transport and companion UI release.

Highlights

• Added optional local Wi-Fi Direct transport alongside USB/AOA.
• Added one-time trust-on-first-use pairing, authenticated reconnect, Android-Keystore-encrypted peer trust, fresh ECDH keys, and AES-256-GCM-protected DBP1 records.
• Added bounded Wi-Fi Direct recovery and transport-neutral DBP1 ownership.
• Reworked the companion Connection screen, navigation drawer, Layout favorites, and Technical details.
• Remembered Output mode and apply it after either Wired or Wireless connection.
• Added selective USB autostart for Rokid glasses and direct glasses exit; double tap remains reserved for exit.
• Improved proxy/VPN route-change resilience by binding wireless sockets to the Wi-Fi Direct network.

Privacy and security

Wireless mode is local-only and needs no router, cloud account, QR code, typed PIN, gesture code, or USB pairing. Android's INTERNET permission is used only for local Java TCP sockets.

Both APKs use the existing Display Bridge release certificate and update in place from v0.2.3.

Display Bridge v0.2.3 — Android 16 hotfix

Display Bridge v0.2.3

Android 16 foreground-service startup hotfix.

Fixed

• Restored the normal CHANGE_NETWORK_STATE permission used by Android as a prerequisite for starting a connectedDevice foreground service before USB device or accessory permission exists.
• Added manifest regression coverage for the prerequisite.
• Verified on Pixel 10 user 0 that the release-signed companion cold-starts without the v0.2.2 fatal SecurityException and remains in the foreground.
• Installed and hash-verified the matching release-signed glasses APK on the target RG_glasses device.

The application does not use this permission to change routing, Wi-Fi, Bluetooth, or the user's audio route.

Both APKs use the existing Display Bridge release certificate. Updating from v0.2.2 works in place.

Display Bridge v0.2.2

Display Bridge v0.2.2

This release prepares the MVP repository for later public access while preserving the release-signing certificate introduced in v0.2.1.

Changes

• Changed the AOA manufacturer to Zhilin.
• Changed the AOA URI to https://github.com/azhilin246/RokidDisplayBridge.
• Removed the unused CHANGE_NETWORK_STATE permission.
• Removed unused FileProviders and their path resources from both APKs.
• Added PolyForm Noncommercial 1.0.0 licensing, a required copyright notice, privacy/security documentation, contribution rules, and Dependabot configuration.
• Removed the five legacy project-name references from OpenSpec and repaired duplicate task numbering without changing completion status.

Upgrade note

The AOA identity changed. Update the companion and glasses APKs together; a mixed v0.2.1/v0.2.2 pair will not match the same accessory manufacturer filter.

Both APKs retain the existing dedicated release certificate, so v0.2.2 can update a release-signed v0.2.1 installation in place.

Verification

• 84 unit tests passed: protocol 13, companion 39, glasses 32.
• Both lintRelease tasks passed.
• Both signed assembleRelease tasks passed.
• APK Signature Scheme v2 and the dedicated release certificate were verified for both artifacts.
• Both OpenSpec changes pass strict validation.
• The release keystore and ignored signing properties were backed up and verified as Bitwarden Secure Note attachments through CLI.
• git diff --check passes.

Long-run, full reconnect/mode-switch, and complete physical gesture acceptance remain explicitly tracked as unfinished OpenSpec tasks.
