Android 0.3.12 — channels, links and QR Codes

MeshCrossway Android 0.3.12 — channels, links and QR Codes

Install as an update over your existing app. The permanent certificate is unchanged and versionCode increases to 33. Do not uninstall or clear storage.

• Meshtastic: create private secondary channels, edit channel name/key and MQTT flags, leave secondary channels, and share primary/selected secondary settings using official ChannelSet links. Primary slot 0 is retained. A secondary share also contains the primary key; confirmation explains this.
• MeshCore: retain private/hashtag/Public creation, editing, removal, scope checks and verified readback.
• Both networks: share a link or QR image, scan a QR Code with the camera, read a saved QR image, paste a channel link or open supported official links in the app. Camera access is optional; image/link import remains available.
• Imports require review and explicit Save to radio. Meshtastic multi-channel links let you choose channels individually. Different LoRa parameters require a separate confirmed save before importing; local region, power and transmit policy are preserved. Join the shared primary first when a secondary needs its automatic frequency. Other slots are not silently replaced.
• Wait for radio readback before sending or sharing during Meshtastic channel/LoRa edits. Historical messages are retained; old channel-key targets cannot send after replacement.

Validation gates include protocol/channel fixtures, QR encoding/decoding unit checks, API 29/35 channel-manager and deep-link instrumentation, migration/persistence, build, lint and permanent certificate verification. Physical-radio, camera and cross-app RF testing are still required; this is a beta.

MeshCore and Meshtastic remain independent, with no cross-network forwarding. The APK checksum and certificate fingerprint are attached.
