Twitter updated its Android client with long overdue usability enhancements and a host of little improvements and bug fixes. Apart from the usual assortment of bug fixes, improvements and polish, Twitter for Android version 3.1, a free download from Android Market, brought back the handy swipe shortcut. Just swipe a tweet in your home timeline to reply, retweet, favorite or share it, or view the Twitter user’s profile without leaving your timeline.

A new confirmation alert was added to the Find Friends feature that now clearly explains that uploading contacts’ email addresses and phone numbers to the Twitter cloud is only used for finding friends on Twitter, provided are discoverable by email or phone number.

The company also said this version of Twitter is optimized for Android devices running Ice Cream Sandwich, as well as on the Kindle Fire, the Barnes & Noble Nook Color, and Nook Tablet. Sadly, you still cannot send long tweets. Release notes after the break.

More information on the changes is available in a post over at the Twitter blog. If you have a Google TV device, Twitter dedicated a client for your set-top box, too. The micro-blogging service also overhauled its iOS client with iPhone-only enhancements, including swipe shortcut, copy, and paste between tweets and profiles, and more.
