Android is a Linux-based operating system designed primarily for touchscreen mobile devices such as smartphones and tablet computers. The Android platform today has built outstanding careers in technology innovation and application development. This platform virtually creates superstar developers who can think differently and who can build small applications quickly. Since its open source, the scope to learn and work is infinite.
Android's source code is released by Google under open source licenses, although most Android devices ultimately ship with a combination of open source and proprietary software. Initially developed by Android, Inc., which Google backed financially and later bought in 2005, Android was unveiled in 2007 along with the founding of the Open Handset Alliance—a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices.
