Google Videos App which allowed Android users to rent movies was only compatible with Android 2.3 (Gingerbread) till today, but Google has updated the App recently for Android that allows even Froyo (Android 2.2) users to take advantage of the movie rentals feature. Once you get the Google Movies App from the Android market, you can rent movies directly from your Android device, and the App will also display all the movies already present on your device.
The App has been designed to work with the newest and updated version of Google Market. As soon as you hit the “Market” icon on the screen within the App, it takes you to the “Movie Rentals” section of the market assuming you already have the latest version. Movie rentals are available for 30 days, but once you start playing the movie, you have only 24 hours to complete it.
Movies can also be streamed over Wi-Fi. You can get the App from here.
