Begginer's Guide for Android



Introduction :-

       Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android was developed by Google and the Open Handset Alliance (OHA), a coalition of hardware, software and telecommunications companies. More than 30 companies were involved in the OHA, including QualcommBroadcomHTC, IntelSamsungMotorolaSprintTexas Instruments and Japanese wireless carriers KDDI and NTT DoCoMo.

       Android began its life as a Palo Alto-based startup company, founded in 2003. That company was subsequently acquired by Google in 2005. The Android platform includes an operating system based upon Linux, a GUI, a Web browser and end user applications that can be downloaded. Although the initial demonstrations of Android featured a generic QWERTY smartphone and large VGA screen, the operating system was written to run on relatively inexpensive handsets with conventional numeric keypads.

Memory Management :-

           Since Android devices are usually battery-powered, Android is designed to manage processes to keep power consumption at a minimum. When an application is not in use the system suspends its operation so that, while available for immediate use rather than closed, it does not use battery power or CPU resources.

Android manages the applications stored in memory automatically: when memory is low, the system will begin invisibly and automatically closing inactive processes, starting with those that have been inactive for longest. Lifehacker reported in 2011 that third-party task killers were doing more harm than good.

Virtual Reality :-

       At Google I/O on May 2016, Google announced Daydream, a virtual reality platform that relies on a smartphone and provides VR capabilities through a virtual reality headset and controller designed by Google itself. The platform will be built into Android starting with version N, differentiating from standalone support for VR capabilities. The software is available for developers, and will be widely released later in 2016.
