Android

Myself

               Hello friends this is Bhanu working as a software engineer on Java and android platform. This is my New Blog here i am going to explore some important and useful topics on Android which helps you to develop Android Apps Hands on friendly.First of all we have to know that what is Android?How it developed?What are the uses of Android Apps.

Android ?

              Android is an open source and Linux-based Operating System for mobile devices such as smartphones and tablet computers. Android was developed by the Open Handset Alliance, led by Google, and other companies.

Android offers a unified approach to application development for mobile devices which means developers need only develop for Android, and their applications should be able to run on different devices powered by Android.

The first beta version of the Android Software Development Kit (SDK) was released by Google in 2007 where as the first commercial version, Android 1.0, was released in September 2008.

On June 27, 2012, at the Google I/O conference, Google announced the next Android version, 4.1 Jelly Bean. Jelly Bean is an incremental update, with the primary aim of improving the user interface, both in terms of functionality and performance.

The source code for Android is available under free and open source software licenses. Google publishes most of the code under the Apache License version 2.0 and the rest, Linux kernel changes, under the GNU General Public License version 2.

Creators of Android
                   The original creators were Android Inc. — led by Andy Rubin, who became the head of Android development at Google after the acquisition in 2005. Google bought the company because they thought Android Inc. had a interesting and important concept — of creating a powerful, yet free, mobile operating system — and its considerable mobile arsenal. Android helped Google to reach a younger audience as well as give the company a number of brilliant employees from Android Inc.

In March 2013, Andy Rubin decided to leave the company he founded, Android, to move on to other projects. However, Android hasn’t missec a step, and replaced him with Sundar Pichai. Pichai used to be the head of Chrome OS — Google’s desktop operating system (for laptops and desktops) — so his experiences leading development teams should be beneficial to Google.

Andy Rubin
                                      
                    Over the course of his 29-year career in Silicon Valley, Andy Rubin has become known as a technical genius, a skilful businessman, and a dynamic leader.

Above all, Rubin is an entrepreneur who loves to create things, whether it's writing code or building robots.

His knack for engineering was evident in Building 44, where Android lives on Google's campus. There, Rubin spent his spare time programming a gigantic robotic arm to make him coffee each time he sent it a text message. The machine was on the second floor of Building 44, and it was large enough to lift cars, a former Googler says.

Another one of Rubin's projects involved flying a massive remote-controlled helicopter on Google's lawn.

"It's this huge $5,000 helicopter - he's trying to pilot it and it takes off and flips over upside down," said Sumit Agarwal, a former head of mobile product management at Google. "And it doesn't explode, but you've got this helicopter that's literally ripped itself apart out on the lawn in front of Building 44.
                                                     In the early 2000s, carriers controlled everything from the way a phone was marketed to how much it would cost. Carriers called the shots back then, and they were determined to keep it that way. They didn't want any company - large or small - infringing on their profits, which is why most of the tech industry thought an idea like Rubin's was impossible, say sources who worked at Google in Android's early days.

While the carrier system was closed and siloed, Android is open. The term "open source" means anyone can take the original source code that makes up Android and use it on their gadgets free. Anyone can build on that code or modify it.

Rubin initially tried to design Android for cameras but couldn't get traction from investors. So he teamed up with Chris White, who previously designed the interface for WebTV, and Nick Sears, a former T-Mobile marketing executive Rubin had worked with when launching the Danger Hiptop, or T-Mobile Sidekick as it was widely known. Rubin explained his idea to create an open-source operating system for phones. Rich Miner, another Android cofounder who leads the East Coast investment team at Google Ventures, joined the group in February 2004.
