Last month, Roku updated its iOS app to let users shoot videos from their iPhones or iPads directly to their Roku devices — a handy, Airplay-style way for those without an Apple TV to liberate video from your iOS device. Now, Roku has gone ahead and added the same functionality to its Android app, which you can download now from the Google Play store. Unfortunately, not all Android users will get this functionality. For starters, it's limited those who own the Samsung Galaxy S III, Galaxy S4, Nexus 4, HTC One, and last-year's Nexus 7. That's a fairly limited set of devices, and Roku didn't say if or when it would roll out functionality to more phones or tablets. Still, it's also some of the most popular devices released in the last year, so many Roku users should be able to take advantage of the new feature.
