2. The Android operating system has grown from a small
development project into one of the most widely
used mobile operating systems that people use on a
daily basis. It has had many stages in growth and
development that has led into the technology that
powers many smart phones and tablet PCs today.
Different versions have been released and
perfected since the original release in 2008.

3. Founded by Andy Rubin and Rich Minor of Palo Alto
teamed up with Chris White and Nick Spears who worked
together to develop the software and associated
technology to produce the highly efficient Android
operating system. While there have been many different
versions of this technology, it is important to realize that
each version of the operating system has helped to
develop the most efficient operating system that is best
for the customer of that point in time.

4. For example, smart phone technology has advanced
so much in the past four years alone, the operating
system of Android needed to advance as well in order
to meet the needs of customers and to be able to
compete with other operating systems on the market
such as that of the Apple iPhone or the
Blackberry.http://eglobiotraining.com/android
5. Android OS Names
While it was only released about four years ago, the
Android operating system has gone through several
different names and versions before settling on the
Android name that is commonly known today. Previous
names include Cupcake, Honeycomb and Jelly Bean among
many others. The Android company worked on developing
this product since the company's inception in 2003 in Palo
Alto, California.

6. ll with backgrounds in IT and web development as well as
software technology, the four men worked on the
software and continued to do so after the company was
acquired by Google in 2005. Since Google had the financial
means as well as the man power to develop the Android
software technology to the maximum extent, this was a
great move for the Android company and led to substantial
advances in the Android operating system and the
product's release in 2008.

source WebKit layout engine, coupled with Chrome's V8 JavaScript engine.
The browser scores 100/100 on the Acid3 test on Android 4.0.Java
supportWhile most Android applications are written in Java, there is no Java
Virtual Machine in the platform and Java byte code is not executed. Java
classes are compiled into Dalvik executables and run on Dalvik, a specialized
virtual machine designed specifically for Android and optimized for battery-
powered mobile devices with limited memory and CPU.J2ME support can be
provided via third-party applications.Media supportAndroid supports the
following audio/video/still media formats: WebM, H.263, H.264, AAC, HE-
AAC (in 3GP or MP4 container), MPEG-4 SP, AMR, AMR-WB (in 3GP

9. Streaming media supportRTP/RTSP streaming (3GPP PSS, ISMA), HTML progressive
download (HTML5 <video> tag). Adobe Flash Streaming (RTMP) and HTTP Dynamic
Streaming are supported by the Flash plugin. Apple HTTP Live Streaming is supported
by RealPlayer for Android, and by the operating system in Android 3.0
(Honeycomb)Additional hardware supportAndroid can use video/still
cameras, touchscreens, GPS, accelerometers, gyroscopes, barometers, magnetometer
s, dedicated gaming controls, proximity and pressure sensors, thermometers,
accelerated 2D bit blits (with hardware orientation, scaling, pixel format conversion)
and accelerated 3D graphics.Multi-touchAndroid has native support for multi-
touch which was initially 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
natively.[9]BluetoothSupports A2DP, AVRCP, sending files (OPP), accessing the phone
book (PBAP), voice dialing and sending contacts between phones. Keyboard, mouse
and joystick (HID) support is available in Android 3.1+, and in earlier versions through
manufacturer customizations and third-party applications.

10. Video callingAndroid does not support native video calling, but some
handsets have a customized version of the operating system that supports
it, either via the UMTS network (like theSamsung Galaxy S) or over IP. Video
calling through Google Talk is available in Android 2.3.4 and later.
Gingerbread allows Nexus S to place Internet calls with a SIP account. This
allows for enhanced VoIP dialing to other SIP accounts and even phone
numbers. Skype 2.1 offers video calling in Android 2.3, including front
camera support. Users with the Google+ android app can video chat with
other google+ users through hangouts.MultitaskingMultitasking of
applications, with unique handling of memory allocation, is
available.AccessibilityBuilt in text to speech is provided by Talk back for
people with low or no vision. Enhancements for people with hearing
disabilities is available as is other aids.

11. Voice based featuresGoogle search through voice has been available since initial release. Voice
actions for calling, texting, navigation, etc. are supported on Android 2.2 onwards. As of Android
4.1, Google has expanded Voice Actions with the ability to talk back and read answers from Google's
Knowledge Graph when queried with specific commands. The ability to control hardware has not
yet been implemented.TetheringAndroid supports tethering, which allows a phone to be used as a
wireless/wired Wi-Fi hotspot. Before Android 2.2 this was supported by third-party applications or
manufacturer customizations.Screen captureAndroid supports capturing a screenshot by pressing
the power and volume-down buttons at the same time.[16] Prior to Android 4.0, the only methods of
capturing a screenshot were through manufacturer and third-party customizations or otherwise by
using a PC connection (DDMS developer's tool). These alternative methods are still available with
the latest Android.External storageMost Android devices include microSD slot and can read
microSD cards formatted with FAT32, Ext3 or Ext4 file system. To allow use of high-capacity storage
media such asUSB flash drives and USB HDDs, many Android tablets also include USB 'A' receptacle.
Storage formatted with FAT32 is handled by Linux Kernel VFAT driver, while 3rd party solutions are
required to handle other popular file systems such as NTFS, HFS Plus and exFAT.

17. Motorola DROID RAZR MAXX
The Droid Razr Maxx packs in a dual-core processor,
large battery and LTE in a very thin frame.
http://eglobiotraining.com/android
18. Samsung Epic Touch 4G
The slim and speedy Samsung Epic Touch 4G is
excellent for gaming, Web browsing and watching
video, but the plasticky design feels a bit on the
cheap side.
http://eglobiotraining.com/android
19. Motorola Droid Razr
The thin and elegant Motorola Droid Razr is smoking
when it comes to data speeds and performance, but
the short battery life is a disappointment.
http://eglobiotraining.com/android
20. Motorola Droid Bionic
The long-awaited Droid Bionic is blazing fast and has a
slew of great entertainment and business features,
but the high price might make it a hard sell.

available, hands down.
