1. Android

2. • Android is a mobile operating system (OS) based on
the Linux kernel and currently developed by Google.
With a user interface based on direct manipulation,
Android is designed primarily for touchscreen mobile
devices such as smartphones and tablet computers, with
specialized user interfaces for televisions (Android TV),
cars (Android Auto), and wrist watches (Android Wear).
The OS uses touch inputs that loosely correspond to
real-world actions, like swiping, tapping, pinching, and
reverse pinching to manipulate on-screen objects, and a
virtual keyboard. Despite being primarily designed for
touchscreen input, it has also been used in game
consoles, digital cameras, regular PCs, and other
electronics. As of 2015, Android has the largest installed
base of all general-purpose operating systems.

3. • As of July 2013, the Google Play store has had
over one million Android applications ("apps")
published, and over 50 billion applications
downloaded.A mobile developer survey
conducted in April–May 2013 found that 71% of
those developers develop for Android with
Android the "priority" target platform in more
cases than iOS or other platforms as of 2015.
At Google I/O 2014, the company revealed that
there were over one billion active monthly
Android users, up from 538 million in June 2013.

4. Android Architecture

5. Android Features

• SQLite
• Video and audio codecs
• Bluetooth, EDGE, 3G, and Wi-Fi
• Camera, GPS, compass, and accelerometer

6. Applications

7. Challenges
• CPU typically runs 500-600 MHz
• RAM available to an App may only be a few megabytes
• Disk (flash) access is very slow
• Lifecycle - apps must pause/quit often, and restore to give
the illusion that they are always running
• UI design
o typical screen may be HVGA (320x480)
o may be in portrait or landscape
o very high DPI - small text may not be readable
o touch resolution is very low (~25 pixel)
• Network access may be slow and (very) intermittent

8. Opportunities
• 100s of millions of mobile phone users
• Very high growth, esp. in Asia
• "Wild wild west" of application development
o think 1985 on the desktop (if you were born by then)
o no dominant 3rd party developers.... yet
o what will the killer app categories be?
o what does it mean to have any app + the internet in
your pocket?
• You can develop for it today!
