5. •
Market share
============== the
By the fourth quarter of 2010 this had grown to 33% of the market, becoming
top-selling Smartphone platform.
•
By the third quarter of 2012 Android had a 75% share
of the global Smartphone market according to the
research firm IDC.
•
In July 2011, Google said that 550,000 new Android
devices were being activated every day.
•
In September 2012, 500 million devices had been
activated with 1.3 million activations per day.

6. Tablets
========
•
initially Android tablet adoption was slow. One of the main causes
was the chicken or the egg situation where consumers
were hesitant to buy an Android tablet due to a lack of high
quality tablet apps.
•
Furthermore, several Android tablets such as the
Motorola Xoom were priced the same or higher than the iPad,
which hurt sales.
•
This began to change in 2012 with the release of the
affordable Nexus 7 and a push by Google for developers
to write better tablet apps .

7. Memory management
Hardware requirements
============================
•
Android devices are incorporating many optional hardware
components, including still or video cameras, GPS, hardware orientation
sensors,
dedicated gaming controls, accelerometers, gyroscopes, proximity
sensors, pressure sensors, thermometers and touch screens.
•
As of November 2013, current versions of Android require at least 512 MB
of RAM and a 32-bit ARMv7, MIPS or x86 architecture processor,
together with an OpenGL ES 2.0 compatible graphics processing unit (GPU).
•
In 2012 Intel processors began to appear on more mainstream Android
platforms, such as phones.
•
Android manages the apps stored in memory automatically:
when memory is low, the system will begin killing apps and processes
that have been inactive for a while, in reverse order since they were
last used (i.e. oldest first), Some third-party task killers are generally
regarded as doing more harm than good.

8. •
Linux kernel
==============
As of November 2013, current Android versions consist of a kernel based on the
Linux kernel version 3.x ,while Android versions older than 4.0 Ice Cream Sandwich
were based on the Linux kernel 2.6.x
