Android is an open-source mobile operating system that powers a wide variety of smartphones. It allows for extensive customization at a low cost. Android phones can download apps, access the internet, manage contacts and calendars, and more. While Android offers developers flexibility, individual phone manufacturers may restrict some phone functions. Choosing an Android phone requires considering factors like carrier, screen size, memory, processor, and more to find the best match for individual needs and usage.

2. Android is a mobile software platform and an
operating system too
• Its an open source which helps you do OS level
customization at minimal cost.
• It has the real power to completely change the
look& feel and the functions of a mobile device.
• Android provides support for Java to develop an
application.
• Third party applications can be created using
Java and Android framework.
• It has approximately 10,072 applications in
market.

3. •An Android™ phone, sometimes called a Droid™
phone, is a mobile telephone that uses the
Google-developed Android™ operating system.
This operating system has become a popular
option in recent years for so-called "smart phones,"
because developers and manufacturers may freely
customize it to their specific needs. This
customization means that different Android™
phones can have widely varying user interfaces.
Most smart phones including those using
competing operating systems offer similar overall
capabilities, however, including Internet browsing,
personal information management, video
streaming, and access to a large repository
of freeware and pay ware applications.

4. Initially, Google partnered with the High Tech Computer
Corporation (now HTC Corporation) to build the first mobile
phone to run the Android™ platform, known as the G1™ in the
United States. In 2008, T-Mobile premiered the G1™ Android™
phone to the American public. Since then, dozens of manufacturers
have brought hundreds of phones with this operating system to
market.
Different generations of smart phones have run various versions of
Android™. Each major software version is identified by a code
name that is usually related to some sort of dessert. While many
phones can be updated to newer versions of the operating system,
this usually cannot be done indefinitely, because of the hardware
limitations of the individual phones. For example, early phones like
the G1™, which initially ran the 1.0 version of Android™, were
eventually upgradable to version 1.6 (Donut), but could not be
upgraded to later versions such as 2.3 (Gingerbread) or 4.0 (Ice
Cream Sandwich), which require more robust hardware.

5. Android platform helps you develop innovative and
dynamic applications and has phenomenal
advantages.
Android offers various advantages to create inventive and modern
mobile applications, follows
• GSM, EDGE, CDMA, Bluetooth, Wi-Fi, EV-DO and
UMTS technologies to send/receive data across mobile
networks.
• Comprehensive libraries for 2D and 3D graphics.
•A wide range of libraries for image, audio and video files.
• Features of Video camera, Touchscreen, GPS,
•accelerometer and magnetometer.
• Interprocess communication (IPC) message passing.
• P2P using Google Talk.
• SQLite for data storage.

6. Android platform also have different disadvantages.
- it force closes apps if they are too large
- it over heats easily during summer
- swipe feature does not work on most texting apps and is
not given on the messaging tool your phone is set with.
the phone itself has very little memory storage, so you
have to keep large apps, videos, and photos on a card.

11. •Android™ offers a Software Development Kit
(SDK) to help developers create functional
applications. While some parts of the Android™
operating system are protected under the
Apache™ License to guard against applications
that could compromise the phones' basic
functionality, much of it is released under the
General Public License, which invites developers
to freely make modifications. The SDK includes
extensive resources and tools to facilitate this sort
of development. It is updated regularly, together
with the operating system itself, and a priority is
placed upon supporting work on both newer and
older versions of Android™.

12. Despite the relatively open structure of the operating system, manufacturers of
many devices that use Android™ do frequently restrict user access to certain
resources and functions within the structure of the software. Typically,
manufacturers do this in order to ensure a consistently stable and predictable
experience by all users, and possibly to maintain a certain level of control over
how their products are used.
"Rooting" is the slang term for using software hacks to circumvent these
restrictions in Android™. Some users opt to do this either in order to expand the
capabilities of a phone or simply as a hobby and for purposes of experimentation.
The process varies, but commonly involves downloading a special file from the
Internet and installing it on the phone from an external memory card. Detailed
instructions on how to root a specific Android™ phone are broadly available
online, though users should be aware that there are risks to doing this. In many
cases, rooting will void a phone's warranty, and there is also a potential that a
device could be rendered useless should something go wrong.

13. •An Android™ phone can run multiple
applications at the same time in the
background, making multitasking easier. This
makes the functionality of the phone more fluid
than some competing platforms, although the
extent of this capability depends on the
hardware of the individual phone. Some
handsets use multicore processors, which are
more useful for "power users" who need their
phones to run multiple simultaneous
operations.

14. Some comparable devices using other operating systems are
governed by strict proprietary rules. Developers interested in writing
applications for the iPhone™, for example, may not be permitted to
create programs that closely mirror applications owned by Apple, such
as iTunes™. All applications must be approved by Apple before they
are permitted to appear in the Apple App Store™. This is not the case
with applications for Android™ phones, which are developed under
the auspices of the Open Handset Alliance, a consortium that
encourages the use and advancement of open source software for
mobile phones.
Another important distinction of the Android™ platform is that it is not
tied to a specific hardware manufacturer. Any manufacturer interested
in producing its own version of an Android™ phone is welcome to use
the operating system. The result is that many competing cellphone
companies now use this platform to power their mobile phones and to
market their devices.

15. 1. Select a cellular carrier that is currently carrying Android phones. Some
carriers may have a carrier-specific version of Android, which could
ultimately impact your decision.
2. Decide between a multi-touch display, a traditional physical QWERTY
keyboard, or a hybrid; this will greatly narrow down your search.
3. Decide on the size and quality of the screen. Four inches has become
the norm for multi-touch screens on smart phones, though they can go as
big as five inches and as small as three. If you plan on watching HD video,
1280 x 720 (720p), is ideal. Any lower than that and the screen will be
more pixilated and worse. Avoid lower than 320 x 480 resolution.

16. 4. Choosing a phone with the technology you require is key. For example, if you
would like to take high quality pictures, a device with a high mega-pixel camera is
ideal. Likewise, if you’d like to use specific third-party peripherals, Bluetooth
technology or integrated ports may be necessary.
5. Consider the memory capacity. Those that want to store music, videos, photos,
and other files on their device will require higher internal memory storage or the
ability to add expandable memory storage.
6. Consider the CPU (or processor) that the phone runs on. This is very important,
as a higher CPU operating frequency allows you to do heavier multitasking and
assures quicker global phone responsiveness and operation. A Quad Core
processor is the fastest currently available. It is ideal if you plan to play games with
amazing graphics. If you are on a budget but still want to use your phone for games,
a Dual Core smartphone is also good. Unless you are only using the phone for the
bare essentials, your Android performance will be hindered by any processor less
than 1Ghz Single Core..

17. 7. Pick a device that supports what most carriers refer to as “multitasking”.
This refers to the ability to use voice and data simultaneously. This is
necessary to take advantage of the Android operating system’s full
capabilities.
8. Select a phone that meets your requirements in terms of weight and
size. Android devices come in various sizes, ranging from tall, slender
touch screens, to more compact designs. Selecting a device with a larger
display will sacrifice portability and vise versa.
9. Compare the battery talk time and standby stats. For those that are
using their device for work or other situations where a long lasting battery
is key, this will be a major consideration when comparing devices.

18. 10. Selecting a device that is capable of handling 4G technology is
necessary to take advantage of 4G networks, which all carriers will
be moving to soon. If you purchase a device that is only 3G-
capable, you will not be able to benefit from the faster 4G networks
once they become available.
