Chrome to Phone is a service that allows users to send web page URLs and notifications from their PC's Chrome browser to their Android devices. It uses Google Cloud to Device Messaging (C2DM) and a Chrome extension to facilitate communication between the browsers and devices. Developers must register with C2DM to receive messaging IDs to identify approved senders. Notifications and URLs are sent from the Chrome extension through C2DM servers to the Android application, allowing users to access web pages on the go.
