Hints of Android devices streaming their screens to a Chromecast appeared months ago and now the feature is live. Officially announced at Google(s goog) I/O, certain Android devices can now mirror their display to a large screen using a Chromecast. The feature is technically a beta and Google says support for additional devices is coming soon. To use the feature, Android users will need the updated Chromecast version 1.7 app found in the Google Play Store. With the right device and updated app, anything you see on your Android’s small screen can now be shared on a larger screen.
