Android, also known as Droid, is the operating system for last generation mobile phones. The OS has been developed by Google and is now the most widely distributed operating system for smartphones in the world, used by more than 33% of the market. Android also runs tablets developed by Google Inc.
The acquisition of Android by Google occurred 6 years ago, 2005 and for the first time it was distributed in November 2007. The exclusion was announced by the establishment of the Open Handset Alliance, which is a group of 80 IT companies working for mobile phone improvements. Most of the code for Android was released by Google under the Apache License, which makes Android licensed as free software.
The operating system is based on Linux kernel and is written with middleware, libraries and C-language APIs, and also contains Java-compatible libraries. Like other popular OS in the market, Apple in iOS, Android is a large database of third-party applications developed by independent programmers or companies, most of which are written in Java. Over 250,000 apps are now available on the Android Market that Google operates. You can also download applications from other sites but it is recommended to use the versions from the official market OS.
Android is now the most popular and world-class smartphone platform, according to Canalys and comScore. Google OS was best sold in the fourth quarter of 2010.
From the original release, some updates were made for Android. Each version of Android has a code number and nickname and the latest versions are: 2.0 Eclair, 2.1 Eclair, 2.2 Froyo, 2.3 Gingerbread, 3.0 Honeycomb, 3.1 Honeycomb and 3.2 Honeycomb. The 4.0 Ice Cream Sandwich version is set to release in the fourth quarter of 2011, which is currently under development and testing.
Android is mainly powered by hardware from ARM architecture. The Android-x86 project offers support for x86 and Google TV uses a special version of Android, which also works on x86. The first smartphone to use Android was HTC Dream, released in October 2008. Google collaborates with HTC for its first Android device, Google Nexus One, but the 2010 version was made in collaboration with Samsung: Google Nexus S.
While it works on Linux kernel, Android had some security issues at the time. In August 2010, SMS Trojan infected a lot of devices, but in March 2011 Google found 58 malicious apps on the Android Market, which were downloaded to about 260,000 devices. Most of the programs were hiding trojans and infecting many devices. The latest survey conducted in August 2011 revealed that about half of Android users were infected with malware in the first half of 2011.
Yet, Android is still one of the most popular operating systems in the world and the only competitor, Apple's iOS , is still set at a distance in ranks.
