Versions
If you've heard of Android, chances are you've heard all about its various versions. Some call it fragmentation, some say it's the nature of open-source, but in reality it's both a curse and a blessing. Regardless, it's good to have a little context about what all these version numbers and names mean when you see them posted on the Internet.
KitKat
Google announced that the next version of Android would be named for their favorite
confectioneries —Kit Kat bars — on September 3, 2013. We're not yet sure what manner of goodies we'll fine in the next version of Andorid, because Google has been understandably cryptic with details.
Their US partner in the deal, Hershy, hasn't been so quiet. They promise an update that really does taste as good as it looks, and offers adjustable orientation that works perfectly in portrait or landscape. If you enjoy a little tongue-in-cheek humor, have a look here and speculate with everyone else.
Android 4.1-4.3 - Jelly Bean
Jelly
Bean arrived at Google IO 2012,
with the release of the ASUS
Nexus 7, followed by a quick update for unlocked Galaxy Nexus phones. Later
in the year, the release of the Nexus 10 and Nexus 4 updated things from 4.1
to 4.2 and on to 4.3, but the version remained Jelly Bean. The release polished
the UI design started in Ice Cream Sandwich,
and brought several great new features :- 
Android 4.0 - Ice Cream Sandwich
The follow-up to Honeycomb was announced at Google IO in May
2011 and released in December 2011. Dubbed Ice Cream Sandwich and finally
designated Android 4.0, Ice Cream Sandwich brings many of the design elements
of Honeycomb to smartphones, while refining the Honeycomb experience.Android 3.X - Honeycomb
Android 2.3
Android 2.3 came out of the oven in December 2010, and like Eclair, has a new "Googlephone" to go along with -- the Nexus S. Gingerbread brings a few UI enhancements to Android, things like a more consistent feel across menus and dialogs, and a new black notification bar, but still looks and feels like the Android we're used to, with the addition of a slew of new language support.
Gingerbread brings support for new technology as well. NFC (Near Field Communication) is now supported, and SIP (Internet calling) support is now native on Android. Further optimizations for better battery life round out a nice upgrade.
Behind the scenes, the fellows at Mountain View spent time with more JIT (the Just-In-Time compiler) optimizations, and made great improvements to Androids garbage collection, which should stop any stuttering and improve UI smoothness. Round that out with new a multi-media framework for better support of sound and video files.
Android 2.2 - Froyo
Android 2.2 was announced in May 2010 at the Google IO conference in San Francisco. The single largest change was the introduction of the Just-In-Time Compiler -- or JIT -- which significantly speeds up the phone's processing power.Along with the JIT, Android 2.2 also brings support for Adobe Flash 10.1. That means you can play your favorite Flash-based games in Android's web browser. Take that, iPhone!
Froyo also brought native support for tethering, meaning you could use your Android smartphone's data connection to provide Internet (wirelessly or with a USB cable) to just about any device you want. Sadly, most carriers will strip this native support in exchange for some sort of feature they can charge for. (Can't really blame them, can you?)
Android 2.0/2.01/2.1 - Eclair
Eclair was a pretty major step up over its predecessors. Introduced in late 2009, Android 2.0 first appeared on the Motorola Droid, bringing improvements in the browser, Google Maps, and a new user interface. Google Maps Navigation also was born in Android 2.0, quickly bringing the platform on par with other stand-along GPS navigation systems.
Android 1.6 - Donut
Donut, released in September 2009, built on the features that came with Android 1.5, and expanded them. While not very rich in the eye-candy department, Android 1.6 made some major improvements behind the scenes, and provided the framework base for the amazing features to come. To the end user, the two biggest changes would have to be the improvements to the Android Market, and universal search.
Android 1.5 - Cupcake
Cupcake was the first major overhaul of the Android OS. The Android 1.5 SDK was released in April 2009 and brought along plenty of UI changes, the biggest probably being support for widgets and folders on the homescreens.
There were plenty of changes behind the scenes, too. Cupcake brought features like improved Bluetooth support, camcorder functions, and new upload services like YouTube and Picasa.
