3. Android is a Linux-based operating system for mobile
devices such as smartphones and tablet computers,
developed by Google in conjunction with the Open
Handset Alliance. Android was initially developed by
Android Inc, whom Google financially backed and later
purchased in 2005 The unveiling of the Android
distribution in 2007 was announced with the founding of
the Open Handset Alliance, a consortium of
86 hardware, software, and telecommunication companies
devoted to advancing open standards for mobile
devices. Google releases the Android code as open-source,
under the Apache License. The Android Open Source
Project(AOSP) is tasked with the maintenance and further
development of Android.
4. Android has a large community of developers writing
applications ("apps") that extend the functionality of
the devices. Developers write primarily in a
customized version of Java, and apps can be
downloaded from online stores such as Google
Play (formerly Android Market), the app store run
by Google, or third-party sites. In June 2012, there were
more than 600,000 apps available for Android, and the
estimated number of applications downloaded from
Google Play was 20 billion.
5. Android became the world’s leading smartphone
platform at the end of 2010. For the first quarter of
2012, Android had a 59% smartphone market share
worldwide.At the half of 2012, there were 400 million
devices activated and 1 million activations per day.
6. Handset layouts The platform is adaptable to
larger, VGA, 2D graphics library, 3D graphics library
based on OpenGL ES 2.0 specifications, and
traditional smartphone layouts.
Storage SQ Lite, a lightweight relational database, is
used for data storage purposes.
ConnectivityAndroid supports connectivity
technologies
including GSM/EDGE, IDEN, CDMA, EV-
DO, UMTS, Bluetooth, Wi-Fi, LTE, NFC and WiMAX.
7. Connectivity Android supports connectivity

DO, UMTS, Bluetooth, Wi-Fi, LTE, NFC and WiMAX.
Multiple Language Support - Android supports
multiple languages .
Web browser- The web browser available in Android
is based on the open-source WebKit layout engine,
coupled with Chrome's V8 JavaScript engine. The
browser scores 100/100 on the Acid3 test on Android
4.0.
8. Streaming media support RTP/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).
9. Java support
While 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.
10. Media support -Android supports the following
audio/video/still media
formats: WebM, H.263, H.264 (in 3GP or MP4
container), MPEG-4 SP, AMR, AMR-WB (in 3GP
container), AAC, HE-AAC (in MP4 or 3GP
container),MP3, MIDI, Ogg
Vorbis, FLAC, WAV, JPEG, PNG,GIF, BMP, WebP.
11. Additional hardware support
-Android can use video/still
cameras, touchscreens, GPS, accelerometers, gyroscop
es, barometers, magnetometers, dedicated gaming
controls, proximity and pressure
sensors, thermometers, accelerated 2D bit blits (with
hardware orientation, scaling, pixel format conversion)
and accelerated 3D graphics.
12. Multitasking of applications, with unique handling
of memory allocation, is available
Voice based features – Google search through voice
has been available since initial release. Voice actions
for calling, texting, navigation, etc. are supported on
Android 2.2 onwards.
Tethering Android 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
13. Screen capture
-Android supports capturing a screenshot by pressing
the power and volume-down buttons at the same
time. 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.
14. External storage
-Most 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 as USB 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.
15. 1. Samsung Galaxy S3
Probably the best smartphone the world has ever
seen. The Samsung Galaxy S3 has a giant 4.8-inch
display which offers up a brilliant picture regardless of
viewing angle or light condition. The phone runs
Android 4.0 ICS, with Samsung’s own TouchWiz UI for
added user experience. There is an 8-MP camera with
an array of features and an impressive 1.4GHz quad-
core processor with 1GB RAM for superior
performance. A truly awesome phone.
16. 2.)The HTC One S is the ultimate multimedia phone,
from gaming to music to snapping high quality photos.
3.) Samsung Galaxy Nexus
The best Android phone to date, the Galaxy Nexus
dazzles with its curved display, sleek design, fast
performance, and, of course, the Ice Cream Sandwich
update.
17. 4.) Motorola DROID RAZR MAXX
The Droid Razr Maxx packs in a dual-core processor,
large battery and LTE in a very thin frame.
5.) 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.
18. 6.) 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.
7.) 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.
19. 8.)Samsung Galaxy S II (T-Mobile)
Like the rest of the Galaxy S II series, the Galaxy S II on
T-Mobile is one of the best phones currently available,
hands down.
9.)HTC Evo 3D
Uneven call quality doesn't stop the Evo 3D from being
the best phone currently available on Sprint.
