What is Android??
How Does Android Operating system evolved?
Android was an advance OS which was actually developed for DIGITAL CAMERAS. But, The founder Andy Rubin then realised that the market for digital cameras was not large enough. So, The company diverted their effort to produce a new open source operating system(based on Linux kernel) for smartphones. this aspect totally convinced Larry Page(Founder of the Google search engine) and gave birth to the Mobile division in Google. After that Android Inc. was acquired by Google Inc. on August 17, 2005 with Andy Rubin, Rich miner and chris white and many others.

Android version 1.0 :
After all the attempts google released their first version on october 22nd 2008. Android 1.0 was a great first start, but there were still so many gaps in functionality. Physical keyboards and tons of hardware buttons were mandatory, as Android devices were still not allowed to be sold without a d-pad or trackball. Base smartphone functionality like auto-rotate wasn't here yet, either. Updates for built-in apps weren't possible through the Android Market the way they were today. All the Google Apps were interwoven with the operating system. If Google wanted to update a single app, an update for the entire operating system needed to be pushed out through the carriers.
Android Version 1.1 :
The android platform was updated for the first time in February 2009. This update was not a revolutionary update. It just included all the patches for the long lengthy bugs list.
As Everyone knows that Each android major release is named in Alphabetical order after a dessert or sugary treat and they started that from now and released the future updates with a dessert name but the name started with letter 'C' instead of 'A'. No one knows what made google to start the name with letter 'C'. This might be because they released 2 updates and next update was 3rd so they might have started name just because of that and now the first update with a sugary treat was Cupcake.......
