+# Android Reference Map
+
+## Core Docs
+
+- Get started: https://developers.zoom.us/docs/virtual-agent/android/get-started/
+- Integration scenarios: https://developers.zoom.us/docs/virtual-agent/android/integration-scenarios/
+- JavaScript events: https://developers.zoom.us/docs/virtual-agent/android/javascript-events/
+- Resources: https://developers.zoom.us/docs/virtual-agent/android/resources/
+
+## Observed Sample Patterns
+
+- Java and Kotlin implementations follow the same bridge contract.
+- Bridge command routing centers around `commonHandler` JSON payloads.
+- `support_handoff` events are emitted from JS and consumed in native layer.
