Brillo and Weave Internals
summary
Brillo is a stripped-down Android distribution that removes the Java framework and application layer so the runtime image shrinks to roughly a tenth of Android’s, and instead runs native C services that open HAL modules directly. Communication moves from D‑Bus to binder-based IPC, with Weave implemented as on-device daemons (weaved + webservd) that parse cloud REST calls and dispatch to registered handlers. The repo uses a Brillo manifest on android.googlesource.com; the sample LED flasher example uses AIDL and hw_get_module to drive the lights, and a Node.js Weave server prototype already demonstrates the protocol is easy to replicate.
