If you stick it in a dock and leave the app running in the foreground, sure–the local zone can be made un-private in settings, and we support synchronization with all RAAT zones, including Android ones.
There’s a small amount of work needed for us to turn that into “RoonBridge for android”. Some settings + network state management to make sure that the RAAT bits boot at startup, keeps the WiFi from turning off, etc. That will happen at some point.
