The Android era: From G1 to KitKat

Android 4.4 KitKat refreshed the operating system with a new design, and ushered in a plan to deal with fragmentation. CNET weighs in on how far the Android OS has come and where it's going next.

Google has come a long way since the early days when it struggled to convince the world that its friendly green extraterrestrial could make applesauce of the revolutionary iPhone.

In truth, Google's first Android phone, the HTC-made T-Mobile G1, wasn't much to look at when it debuted in October 2008, with its trough for a keyboard and its bizarrely jutting chin. HTC was hardly a known brand, and we weren't even sure if we were getting a single Google Phone or an entire operating system. Still the humble G1, with its ugly design and few apps, kicked off an Android avalanche just the same.

Now in 2014, Android and iOS both command the smartphone market (CNET's Jason Parker outlines the history of iOS here). Yet for all the platform's success, too many versions of the operating system are available at the same time across handsets and carriers. Whether you call that fragmentation or not, Google is actively trying to change it. When the company released version 4.4 KitKat in 2013, it made a big push to make its operating system smaller, so that it could run on budget devices with small amounts of internal storage and just 512MB of RAM (most flagship Android phones have 1GB or more). And yet, while some Android device manufacturers are starting to build KitKat phones, we still see plenty of brand-new low-end devices released with Jelly Bean 4.3 and 4.2. At least for the foreseeable future, the fragmentation problem is here to stay.

A little perspective tends to go a long way, and in light of that, here's a look at the major milestones in Google's Android operating system, from its humble beginnings to its current ambitions in smartphone and tablet domination.

Android 4.4 KitKat

Android KitKat was released on October 31, 2013, and brought with it a bunch of design changes, most of which were only noticeable on the new Nexus 5 handset. While there have always been differences between Android on a Nexus device and Android on every other phone or tablet, the Nexus 5 took on a completely new look thanks to the Google Now launcher (originally called the Google Experience launcher), a home screen replacement with a transparent app drawer, large icons, and a dedicated Google Now screen.

On other Android phones and tablets, KitKat's additions are a bit more subtle. On most phones, you'll now see a transparent status bar, instead of the earlier black bar, on the home screen and in some apps. KitKat also brings wireless printing to the entire OS, so you can print photos, websites, documents, and more from your phone or tablet, as long as you've set up Google Cloud Print.

Android's future

At the time of this update, we are a little more than a month away from Google I/O 2014, the company's development conference, where it often announces new products, software updates, and more. What we'll see at the event is still up in the air, but it's possible we'll get a shiny new Android update. It might be version 4.5, or Google could finally jump to a new number with 5.0. Either way, rumors say the next flavor of Android will be named Lollipop, and debut on a new 8-inch Nexus tablet. We can't wait to sink our teeth into it.
