If you've been watching television in the United States over the past couple of months, you've probably heard all about what "Droid Does." Verizon and Motorola launched their latest Droid handset with a media blitz touting both the phone and the Android OS that powers it.

For many consumers, this was probably the first time they'd heard of Android. So before your end users call you up and pepper you with questions about the mobile OS, check out this cheat sheet for Android.

The basics

Android is an open source software stack for mobile devices being developed by Google and the Open Handset Alliance. It includes an operating system, middleware, and key applications such as Maps.

Android runs on the Linux kernel, and the source code is available under an Apache License. There is also an SDK and an API that allows developers to create apps for Android handsets.

There are several online resources dedicated to Android. If you want to dig deeper into the technology side of Android, see:

Like the iPhone and its iTunes store, there is an Android Market that allows users to download both free and paid apps for their Android handsets. There are currently over 20,000 apps available.

Because Google has been so involved with the development of the OS, many of its apps are front and center in Android, including Gmail for email, Google Maps for navigation, Google Search and Voice Search for search, YouTube for video, and Picasa for photos.


There are currently around 20 Android-powered mobile handsets available worldwide, with seven of those available in the United States. Android has also been included in netbooks by Acer, tablets by Archos, and e-readers such as the Barnes & Noble nook. The following table lists the seven mobile handsets that are currently available in the United States.

The future

All of the buzz around Android in the past couple of months has focused on the Google Nexus One (aka "The Google Phone") handset. While the initial launch was met with a lot of anticipation, sales haven't (yet) lived up to the expectations. Screen issues and a 3G bug haven't helped things in the weeks following the launch.

Despite these issues, the Nexus One is significant for the following reasons:

  1. It was offered exclusively through a software company, not from a major wireless provider, and was sold directly to consumers.
  2. Despite being coupled with T-Mobile USA at launch, the long-term plan is for the Nexus One to be carrier-agnostic.
  3. It was offered with two payment options: contract-subsidized ($179) and contract-free ($529).
  4. It showed that an Android phone could build the kind of buzz that had previously been reserved for the iPhone.

Not to be outdone by the Nexus One, AT&T kicked off 2010 with the announcement of five new Android handsets at the Consumer Electronics Show (CES) in Las Vegas. This means that, in the first half of this year, U.S. consumers will be able to choose Android on the four largest carriers.
