Amidst the clamoring of all things mobile at the Mobile World Congress in Spain, StumbleUpon announced an update to their mobile app for Android today that will feature a bevy of new features. Android users can look forward to a deeper integration to Google+ as well as improved sharing capability through Android Beam, the Bump-like app that allows users to share information by simply touching the backs of two Android devices together.

Unlike in previous versions, users will now be able to sign in to StumbleUpon using their Google Account. In doing so, users can create a new StumbleUpon account that will integrate their Google sign-in credentials. The interweaving of Google accounts will make it easier for users to share content they come across on StumbleUpon to their Google+ Circles (if that’s how you’re inclined). Users have previously been able to sign in and create accounts with StumbleUpon using Facebook and Twitter account info, but the addition of Google completes the tri-force of major social networking sites.

“We are excited to work with Android and showcase our updated mobile app more prominently on the Android platform,” said Garrett Camp, co-founder and CEO, StumbleUpon. “This integration will let many more people find new and interesting things from across the Web on their Android devices.”

Additionally, the StumbleUpon app update will include the native Android Action Bar, enabling users to explore the Web via the Android navigation interface.

Updates to iOS, NOOK Color, and Kindle Fire were released today as well, finalizing a cross-platform consistency with StumbleUpon in aesthetic and function.

One final note about StumbleUpon using Android Beam: for the sharing feature to work, both Android devices will need to be equipped with Android 4.0, Ice Cream Sandwich.
