AirCast for Android streams to Chromecast from your Gallery, Dropbox, Google Drive
Those who have read our review already know that Google's Chromecast is a great little gadget. It does have its limitations, however, and one of them is that only a handful of Android apps, such as YouTube or Google Play Music, can stream data to the dongle. Koushik Dutta, who is known for his work on ClockworkMod and CyanogenMod, wasn't happy with this so he made AirCast. It is an easy-to-use Android app that beams media over to Chromecast from apps that are not officially supported at this time. These include Dropbox, Google Drive, and the stock Android Gallery application.
But while AirCast is free to download, Koush notes that his app is in an early stage of its development, released for the purpose of collecting user feedback and bug reports. Nevertheless, anyone who has a Chromecast dongle (or an Android device running CheapCast) is free to give it a try.
