Multi-device Development
summary
Google publicly launches the Cross-device SDK as a developer preview, restricted to Play Services beta with weekly updates, open sourced on GitHub and backed by Kotlin and Java sample apps. It currently supports phone↔tablet only, limits sessions to two devices, and exposes a higher-level Sessions API for transfer versus share semantics (transfer moves state, share creates a bi directional secondary session). For testing Google builds NetSim integrated with AVDs and Mobly (2017 project used by millions of tests per month) to simulate BLE Wi‑Fi UWB NFC radios and packet loss.
