Several years ago when Amazon launched their Prime Instant video service they made the rather odd decision to offer fairly limited on-device support and even much more limited support for portable devices like Android based smartphones and tablets. However, the company has recently began working to alleviate that issue, offering minor updates to their applications. The roll-out of these updates has been a rather slow process though, with Android smartphones receiving the updated app late last summer.
Today, thanks to an update to the Amazon Prime Instant Video app (version 188.8.131.520), Amazon is finally offering support for those users who want to stream video content to their Android tablets (via Android Police). Previously, Prime Instant Video only worked with Android phones, and more recently with Fire devices and iOS devices.
Now watch Amazon Instant Video on your Android phones and tablets. Instantly stream thousands of movies and TV episodes, including Amazon Originals, at no additional cost with your Amazon Prime membership. You can also rent or buy from our catalog of hundreds of thousands of videos, including new release movies and current TV shows. On Android phones, this app lets you watch videos from the Amazon app for Android phones, available from http://www.amazon.com/androidapp. On Android tablets, this app enables watching videos in your mobile web browser.
The functionality of the app is still fairly limited, so not much has really changed there—to find and view content users need to launch Prime Instant Video from their devices web browser, but they will then be able to watch on their tablets. Additionally the app is currently only available through Amazon's own Appstore so you will need to install it directly from there. You can find the direct link here.
