There are currently over

Android that are made
accessible through the
Android Market, which is
the online app store run
by Google.
The apps are primarily
written in Java.

Android Inc. was founded in
Palo Alto, California in
October, 2003 by Andy
Rubin, Rich Miner, Nick
Sears, and Chris White.
Their goal was to develop a
"smarter mobile device that
was more aware of its
owner's location and
preferences.”
They operated secretively,
admitting only that they
were working on software
for mobile phones.



Google acquired Android
Inc. in August, 2005,
making Android Inc. a
wholly owned part of
Google Inc.
Nick Sears was the only
original founder that did
not stay with Android Inc.
after the acquisition.
At this point in time,
many assumed that
Google was planning to
enter the mobile phone
market with this move.



Once at Google, Rubin led
a team to develop a
mobile device platform
powered by the Linux
kernel.
Google marketed the
platform to handset
makers and carriers with
the intent of providing a
flexible, upgradable
system.
This caused speculation
about Google's intention
to enter the mobile
communications market
to build.
On October 21st, 2008,
Android 1.0 became
available to the public.
 "Today's announcement is
more ambitious than any
single 'Google Phone' that the
press has been speculating
about over the past few
weeks. Our vision is that the
powerful platform we're
unveiling will power
thousands of different phone
models.“
-Eric Schmidt, former
Google Chairman/CEO

Android has support for
multi-touch which was
originally made available
in handsets such as the
HTC Hero.
The feature was originally
disabled at the kernel
level (possibly to avoid
infringing Apple's patents
on touch-screen
technology at the time).
Google has since released
an update for the Nexus
One and the Motorola
Droid which enables
multi-touch.
