<span style="text-align: left;">NASA the space agency is sending Android-powered mini-satellites into space sometime in 2013. Its easy-to-use and tweak-able operating system is likely the reason why NASA chose to send these mini-computers into space to help ‘capture digital imagery of the Earth’.</span><br />

Nonetheless, commercial products are the ones that come from military prototypes, not the way around, which begs the question, how did Android made the climb to stellar proportions, literally, in less than a decade? We take a look at the mobile operating system powering today’s Android devices.<span id="more-1254" style="border: 0px; font-family: inherit; font-style: inherit; font-weight: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;"></span></div>

The acquisition of Android Inc by Google in 2005 marked Google’s entry into the smartphone market. Today, <a href="http://www.prweb.com/releases/2012/5/prweb9514037.htm" rel="external" sl-processed="1" style="-webkit-transition: all 0.2s ease-in; border: 0px; color: #e94f1d; font-family: inherit; font-style: inherit; font-weight: inherit; margin: 0px; outline: 0px; padding: 0px; text-decoration: none; transition: all 0.2s ease-in; vertical-align: baseline;" target="_blank">Android is on over 331 million smartphones</a> with close to a million joining every day. Its popularity was encouraged by monthly billion-app downloads from Google Play. The Android app store <a href="http://www.engadget.com/2012/06/27/google-play-hits-600000-apps/" rel="external" sl-processed="1" style="-webkit-transition: all 0.2s ease-in; border: 0px; color: #e94f1d; font-family: inherit; font-style: inherit; font-weight: inherit; margin: 0px; outline: 0px; padding: 0px; text-decoration: none; transition: all 0.2s ease-in; vertical-align: baseline;" target="_blank">features 600,000 apps</a> so far.</div>

<div style="text-align: justify;">
Android runs on more than 250 devices, inclusive of tablets and smartphones that are produced by 23 different manufacturers, and has gone through more than ten OS updates from Android 1.0 (presumably named Astro) until the much-anticipated Android 4.1, Jelly Bean, released in June this year.</div>
</div>
<h3 style="border: 0px; clear: both; color: #36312d; font-family: Muli, Helvetica, Arial, sans-serif; font-size: 3rem; font-style: inherit; font-weight: 300; letter-spacing: -0.04em; line-height: 1.6; margin: 0px 0px 2.4rem; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;">
Android 1.0 Astro</h3>
<div style="border: 0px; color: #36312d; font-family: inherit; font-size: 14px; font-style: inherit; font-weight: inherit; line-height: 22px; margin-bottom: 2.4rem; outline: 0px; padding: 0px; vertical-align: baseline;">
<div style="text-align: justify;">
Android 1.0 was launched in Sept 2008, with features that were mainly oriented for business and work purposes.</div>
</div>
<div style="border: 0px; color: #36312d; font-family: inherit; font-size: 14px; font-style: inherit; font-weight: inherit; line-height: 22px; margin-bottom: 2.4rem; outline: 0px; padding: 0px; vertical-align: baseline;">
<div style="text-align: justify;">
This version was packed with great apps and support for using the Internet and Internet-based services such as: full HTML support in the browser, video playback with a YouTube app, and Google services like GTalk, Gmail, Google Maps and Google Sync.</div>
</div>
<div style="border: 0px; color: #36312d; font-family: inherit; font-size: 14px; font-style: inherit; font-weight: inherit; line-height: 22px; margin-bottom: 2.4rem; outline: 0px; padding: 0px; vertical-align: baseline;">

<img alt="" height="375" src="http://media02.hongkiat.com/android-evolution/android-astro.jpg" style="max-width: 100%;" width="500" /></div>

<div style="text-align: justify;">
It was also the first mobile operating system to pull off the pull-down notification window, and users first learn of the uses of Widgets and apps that can be downloaded and updated via the Android Market even though the market wasn’t as heavily populated then as it is now.</div>
</div>
<div style="border: 0px; color: #36312d; font-family: inherit; font-size: 14px; font-style: inherit; font-weight: inherit; line-height: 22px; margin-bottom: 2.4rem; outline: 0px; padding: 0px; vertical-align: baseline;">
<div style="text-align: justify;">
Thus, this version was mainly focused on lifting the business side of smartphones, with a lack of focus on entertainment features – Android users have minimal control over the Camera, and there’s no support for video playback in its media player. Android 1.1 (presumably Bender) featured mostly bug fixes and updates, and was the first ever software update for Android.</div>

<div style="text-align: justify;">
<strong style="border: 0px; font-family: inherit; font-style: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">Cupcake</strong> was Android’s second major release, but the first commercially available version, which featured a good amount of bug fixes, and plenty of good features. It was introduced together with Android’s first touchscreen-only phone: the HTC Magic.</div>
</div>
<div style="border: 0px; color: #36312d; font-family: inherit; font-size: 14px; font-style: inherit; font-weight: inherit; line-height: 22px; margin-bottom: 2.4rem; outline: 0px; padding: 0px; vertical-align: baseline;">

<div style="text-align: justify;">
Widgets were introduced; Google started allowing third parties to produce widgets for Android use. Cupcake also enabled the copy-and-paste feature – which we so take for granted now – from plain text on a page to internal apps.</div>
</div>
<div style="border: 0px; color: #36312d; font-family: inherit; font-size: 14px; font-style: inherit; font-weight: inherit; line-height: 22px; margin-bottom: 2.4rem; outline: 0px; padding: 0px; vertical-align: baseline;">
<div style="text-align: justify;">
Users can easily swap between Still Camera and Video Camera modes with a single touch and without leaving the camera app. Video recording was made available in MP4 and 3GP formats and the auto screen rotate that we see in our devices was added in this version.</div>
</div>
<div style="border: 0px; color: #36312d; font-family: inherit; font-size: 14px; font-style: inherit; font-weight: inherit; line-height: 22px; margin-bottom: 2.4rem; outline: 0px; padding: 0px; vertical-align: baseline;">

<div style="text-align: justify;">
App screenshots are now available in the Android Market. The new update also allow for WVGA Screen Resolutions and better performance. The Gallery was fully integrated with the Camera apps for better and faster viewing of photos taken from the camera.</div>

<div style="text-align: justify;">
Eclair, Android 2.0 and its update 2.1, was released in Oct 2009, bringing in a revamped user interface (UI) and the introduction of Live Wallpapers (animated wallpapers at the homescreen).</div>
</div>
<div style="border: 0px; color: #36312d; font-family: inherit; font-size: 14px; font-style: inherit; font-weight: inherit; line-height: 22px; margin-bottom: 2.4rem; outline: 0px; padding: 0px; vertical-align: baseline;">

<div style="text-align: justify;">
Android users were also treated to the virtual keyboard for a faster typing experience and if typing takes too long, then the speech-to-text technology is the best alternative. There’s also Bluetooth 2.1 support for faster file transfers.</div>
</div>
<div style="border: 0px; color: #36312d; font-family: inherit; font-size: 14px; font-style: inherit; font-weight: inherit; line-height: 22px; margin-bottom: 2.4rem; outline: 0px; padding: 0px; vertical-align: baseline;">
<div style="text-align: justify;">
Users who have multiple emails could browse their multiple accounts at the same time and the Account sync enables synchronization of email and contacts easily. Calling or texting friends has become a lot easier by using a long press over the wanted Contact Name, then selecting to Call or Text them. The Camera app on Android 2.0 has flash support, Scene Modes, white balance, and digital zoom among others. That double-tap that allows you to zoom into text on a browser?</div>

<div style="text-align: justify;">
Come May 2010, Android 2.2 or “Froyo” – Frozen Yogurt – blew the competition away in terms of OS speed thanks to the Java V8 engine and JIT compiler which launched apps faster than ever.</div>

<div style="text-align: justify;">
Android users can also now run Flash on their Android device and are treated to picture preview stacks in the 3D photo shots gallery without selecting to see the full photo first. Also worth mentioning is the remote wipe features that allow you to wipe out your data in the event of a lost or stolen phone for better data protection.</div>

<div style="text-align: justify;">
Android 2.3 (Gingerbread) came to light at the end of the year, a mere six months later after Froyo made headlines. Users are able to quickly switch between front and back camera in the modified camera app. Copy-paste can now be done word by word (press-hold to select) rather than by blocks of text.</div>

This version also has better battery management tools allowing users to see which app is zapping battery juice the most. Its last update v2.3.7 introduced Google Wallet which utilizes near field communication to store cards, redeem promotions and even make secure payments from your phone.</div>

Android 3 (Honeycomb)</h3>

<div style="text-align: justify;">
Taking a break from smartphones is the Android 3.0, Honeycomb update which was designed with tablets in mind. Everything is on the UI now with no need for physical buttons. The Back and Home keys get perpetual spots at the bottom of the screen. Widgets become more prominent as developers get more room to play with due to the larger screen size.</div>
</div>
<div style="border: 0px; color: #36312d; font-family: inherit; font-size: 14px; font-style: inherit; font-weight: inherit; line-height: 22px; margin-bottom: 2.4rem; outline: 0px; padding: 0px; vertical-align: baseline;">
<div style="text-align: justify;">
In the main view, one can see two bars: at the top the Action bar, which gives access to individual apps and widgets, at the bottom, the System bar showing notifications and soft navigation buttons.</div>

<div style="text-align: justify;">
The additional space also allows for a better, redesigned keyboard for more accurate presses and efficient typing. Browsers carry multple tabs and is available in ‘incognito’ mode, while the Contacts and Email UI carry two panes now for better organization and access of data. This version also has better hardware acceleration and 3D graphics support. Later updates (still under Honeycomb) added connectivity of USB accessories such as external keyboards or gamepads as well as improved handwriting prediction for Chinese characters.</div>

<div style="text-align: justify;">
Android 4, first released on Oct 2011 and updated in March 2012, is also known as Ice Cream Sandwich, continuing the dessert-naming convention. It had then unmatched performance and speed, carrying many of the features that Honeycomb installed in tablets over to smartphones including being rid of physical buttons for navigation.</div>

The launcher is now customizable and users can add both apps and widgets (which has since been separated) into their homescreens or panels via drag-and-drop. Default keys docked at the bottom of the homescreen can also be customized and carry multiple folders (or apps) which appear stacked together. Select icon once to see options; select again to launch the app.</div>

Users can now use video chat in GTalk in this version, which also carries Face Lock. The Task Manager now carries screenshots of recently open or currently in use apps which can be dismissed (and closed) individually by swipping them off the screen.

Usage can be broken down by time spent on any and all apps, for better battery management and users can also receive warnings when breaching data limit, or disable data usage once it surpasses a preset limit. It also has an integrated snapshot capture feature which is initiated by pressing both the power button and the volume-down button together. A shutter sound indicates that a shot has been taken. Screenshots take up a separate folder in the gallery.</div>

Initiate it by holding down the Home button and swiping up to get predicted suggestions and updates on Cards, based on your past searches and latest locations. At least, Google is putting all that gathered intelligence to good use – you get your own personal assistant, who knows you inside out and brings updates to your attention even before you ask for it.</div>

Voice search is part of the implementation in Google Now (so ask away), as Voice dictation is now an offline, integrated feature. Jellybean is already running on Google Nexus smartphones and the tablet</div>

</div>
<div style="margin-left: 10px; margin-right: 10px;">
The following description assumes that you already have a flavor of the Eclipse IDE installed which you want to update to develop Android applications. Use the Eclipse update manager via <b><span class="guimenu" style="font-style: italic;">Help</span> → <span class="guisubmenu" style="font-style: italic;">Install new software</span></b> and start the <b><code class="filename" style="font-style: italic;">android</code> </b>to install all available components for the Android Development Tools (ADT) from the following URL:</div>
<div style="margin-left: 10px; margin-right: 10px;">
</div>
<pre class="programlisting" style="background-color: #ffffee; border-bottom-left-radius: 9px; border-bottom-right-radius: 9px; border-top-left-radius: 9px; border-top-right-radius: 9px; border: 1px solid rgb(187, 187, 187); font-family: 'Droid Sans Mono', Monaco, 'Bitstream Vera Sans Mono', 'Lucida Console', Terminal, monospace; font-size: 12px; line-height: 15px; margin: 10px; overflow: auto; padding: 1em; word-wrap: break-word;"><a href="https://dl-ssl.google.com/android/eclipse/" target="_blank">https://dl-ssl.google.com/android/eclipse</a></pre>
<div style="margin-left: 10px; margin-right: 10px;">
</div>
<div style="margin-left: 10px; margin-right: 10px;">
After the new Android development components are installed, you will be prompted to install the Android SDK. You can use the following wizard or go to the next section to learn how to do it manually.</div>

<div style="margin-left: 10px; margin-right: 10px;">
After the installation of the ADT the Eclipse tooling allows to download the Android SDK automatically. Alternatively you can also manually download the Android SDK from the Android SDK download page.</div>
<div style="margin-left: 10px; margin-right: 10px;">
</div>
<pre class="programlisting" style="background-color: #ffffee; border-bottom-left-radius: 9px; border-bottom-right-radius: 9px; border-top-left-radius: 9px; border-top-right-radius: 9px; border: 1px solid rgb(187, 187, 187); font-family: 'Droid Sans Mono', Monaco, 'Bitstream Vera Sans Mono', 'Lucida Console', Terminal, monospace; font-size: 12px; line-height: 15px; margin: 10px; overflow: auto; padding: 1em; word-wrap: break-word;"><a href="http://developer.android.com/sdk/index.html">http://developer.android.com/sdk/index.html</a> </pre>
<div style="margin-left: 10px; margin-right: 10px;">
</div>
<div style="margin-left: 10px; margin-right: 10px;">
The download contains a zip file, which you can extract to any place in your file system, e.g., on my Linux system I placed it into the <code class="filename" style="font-style: italic;">/home/vogella/android-sdks</code> folder. Avoid using spaces in the path name, otherwise you may experience problems with the usage of the Android SDK.</div>
<div style="margin-left: 10px; margin-right: 10px;">
You also have to define the location of the Android SDK in the Eclipse Preferences. In Eclipse open the Preferences dialog via the menu <span class="guimenu" style="font-style: italic;">Window</span> → <span class="guisubmenu" style="font-style: italic;">Preferences</span>. Select Android and enter the installation path of the Android SDK.</div>
