Android Operating System

Android is based on a modified version of the Linux kernel and other open source software. Designed primarily for touchscreen mobile devices such as smartphones and tablets. It is also a mobile operating system purchased and developed by Google.

Initially developed by Android Inc. and bought by Google 2005. Google released its Beta mobile phone operating system, Android, on the 5 November 2007. The same year Apple also launched the iPhone, with Google releasing its first SDK one week later, on 12 November.

Android is also linked with a host of top software developed by Google, known as Google Mobile Services (GMS) that often comes pre-installed in devices. These software usually includes the Google Chrome web browser and Google Search and always includes default apps for services such as Gmail. Also, digital distribution platform Google Play, and associated development platform, as well as the application store.

The version history of the Android mobile operating system started with the public discharge of the Android beta on November 5, 2007. The first commercial version, Android 1.0, was also released on September 23, 2008. During the early stages of its accelerated development, Android had a very aggressive release schedule. We often saw multiple releases per year, and at its peak in 2009 Android received no-less than four significant updates. More recently, Google has settled into yearly major updates.
