As of 2011, Android has the largest installed base of any mobile OS and as of 2013, its devices also sell more than Windows, iOS, and Mac OS devices combined. As of July 2013 the Google Play store has had over 1 million Android apps published, and over 50 billion apps downloaded. A developer survey conducted in April–May 2013 found that 71% of mobile developers develop for Android. At Google I/O 2014, the company revealed that there were over 1 billion active monthly Android users (that have been active for 30 days), up from 538 million in June 2013.
Android's source code is released by Google under open source licenses, although most Android devices ultimately ship with a combination of open source and proprietary software. Initially developed by Android, Inc., which Google backed financially and later bought in 2005, Android was unveiled in 2007 along with the founding of the Open Handset Alliance—a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices.
Android is popular with technology companies which require a ready-made, low-cost and customizable operating system for hi- tech devices. Android's open nature has encouraged a large community of developers and enthusiasts to use the open-source code as a foundation for community-driven projects, which add new features for advanced users or bring Android to devices which were officially released running other operating systems. The operating system's success has made it a target for patent litigation as part of the so-called "smartphone wars" between technology companies
Advantages of Android over other OS are :-
2)Uses of tools are very simple.
3)Availability of Apps:-majority of the apps in Google Play are free as compared to the paid apps on iPhone.
4)Inbuilt support for the Flash.
5)Great social networking integration
6)Integrated Applications & Features:- Eg:Android allows an option to share, after taking a photo with the Camera.
7)Free to customizes:-You can customize widgets as you wish to.
8)Better Notification System(comprises emails, updates from various widgets.)
9)Updated user interface design
Disadvantages of Android OS
Cons of Android no.1 : Hangs a lotAndroid is good at lagging and continuously hanging your phone, whatever you do it annoys a lot. Whether you are playing “Temple Run” or you are browsing your gallery or you are surfing internet, its hangs a lot
Cons of Android no.2 : Drain battery
Another disadvantages of Android is its drain battery very fast. You play games for 5 minutes and your battery meter drop from 98 to 82. This is how android sucks and eat up your battery as soon as you touch your phone.
Cons of Android no.3 : Internet connection is important
From signing in to Google account (For Android) to do any
bull shit, it needs internet connection, thanks to all those telecom service
providers who offers discount on GPRS pack, or we have to move to Nokia 1100
Cons of Android no.4 : Over heats
This is serious problem for me, Android heats cell phone
often. However if you have a good cover on your cellphone you may feel less
heat, but if without cover just put your cellphone on your cheek you will find
what I mean
Cons of Android no. 5 : Box of Malware Google play store
I agree that Google play has some nice applications sorry
many nice applications but somehow spammers, hackers are ahead of putting
malware in Google play store. If you download 10 Applications a day, 6 will be
shit or malware, so be careful

Android is a relatively new mobile operating system, and if
you're not a tech whizz then getting to grips with all of Google Android's
features can be a bit of a daunting task. Don't worry though, because here's
our beginner's guide on how to use an Android smartphone and tablet.
The Android operating system has been around for years, but
the latest version - 4.4 KitKat - is better than ever and a great alternative
to Apple's iOS.
The latest Android smart phones and tablets provide such
good performance without breaking the bank, too. Although not hard to fathom,
if you are just starting out with Android, this guide is for you.
To get you up to speed, we’ll show you how to set up a new
phone and use it to do a range of tasks.
We’ll start with the basics such as making a call, sending a
text or email and taking a photo, and we’ll work our way up to more advanced
stuff like finding and installing apps, navigating using Google Maps, listening
to music, and watching videos.
We’ve chosen to illustrate this guide using the brilliant
Motorola Moto G, reviewed, which is one of the best budget smart phones ever
and runs the latest version of Android, namely 4.4 KitKat.
However, if you have a different phone, or perhaps even a
tablet, the vast majority of what we cover here will still apply. The exact
appearance of the screen may be different – because Samsung and other
manufacturers like to change Android around, tweaking the look of the launcher
and keyboard, for example – but the basic principles are the same.
How to use Android:: Getting Started
Before you can use your new phone you’ll need to enter a few
details and choose some settings. This is easy. You’ll be asked to choose your
language and select your home Wi-Fi connection so that you won’t pay to use data
over the mobile phone network (3G) when you’re at home. When the phone is
within range of the Wi-Fi network, it will automatically switch from mobile
data to use your wireless broadband connection instead.
Throughout the procedure, if you’re unsure about something
just accept the default since you can always change these settings later.
How to use Android: Google account
Of particular importance is a Google account. While you can
use the phone without providing account details, you’ll miss out on so much of
the Android experience. Only if you have a Google account, for example, can you
obtain apps from Google Play, synchronize your phone with online data in Google
Drive and so much more.
What’s more, quite a few of the instructions later in this
article assume you have a Google account so this is highly recommended. If you
already have an account you’ll only have to enter your username and password.
If not, you’ll have to set one up. You can do this either on your PC by going
to accounts.google.com or just follow the instructions on your phone.
One stage of the setup offers to migrate your settings from
an old phone. However, this only works if your old phone was a Android one.
We’ll see later how to transfer your contacts from a non-Android phone.
How to use Android: Wallpaper and home screen apps
To make you phone unique, how about picking a new wallpaper?
Just hold your finger on the current wallpaper for a second and, when ‘choose
wallpaper from’ appears, touch ‘Wallpaper’. Drag across the options at the
bottom to see full-sized previews and, when you’ve made your choice, touch ‘Set
wallpaper’.
Another aspect of customization is putting frequently used
apps on your home screen. Initially just a handful of commonly used apps will
be on your home screen but, to add more, touch the apps icon (the circle with
the six squares inside) and hold your finger on any apps you want to appear on
your home screen.
How to use Android: Turning Wi-Fi, Bluetooth, GPS on and off
To quickly turn features that drain your battery off when
you’re not using them, and back on again later, swipe down from the top of the
screen. Initially you’ll see status information in which case you should touch
the icon in the top-right corner. Now you can turn Wi-Fi, Bluetooth and Location
(i.e. GPS) on and off.
Finally, a few
general points before we continue. If you don’t do anything for a few seconds
the screen will turn off to save power.
Pressing the power button will bring it back but, unless you
do this immediately, the screen will be locked, as indicated by the padlock
symbol. To unlock, touch the padlock and drag it to the edge of the circle.
How to use Android: Android navigation controls
The backwards-pointing arrow at the bottom-left of the
screen will take you back to the previous page or menu, the house icon in the
center at the bottom will take you to your home page, and the icon that looks
like two sheets of paper at the bottom-right shows, and allows you to switch to
or close, recently used apps.
How to use Android: Beginner's guide to Android: Common
tasks
Let's look at how to perform common actions on your phone.
If the appropriate app is on the home page by default we’ll say so. Otherwise,
you’ll find it by tapping on the apps icon (the six white squares inside a
circle) from the home page, selecting the ‘Apps’ tab if the ‘Widgets’ tab is
displayed, and swiping left or right, as necessary, until you see it.
How to use Android: Secure your Phone
You already know that your phone will lock automatically so
it won’t inadvertently dial a number or send a text by rattling around in your
pocket or handbag. However, you can also ensure that no-one other than yourself
can unlock it.
In the Settings app, scroll down to the Personal section,
select ‘Security’, then ‘Screen lock’ and finally ‘PIN’. Now enter your chosen
PIN, which must be at least four digits long, confirming it when requested. In
future, whenever the screen locks and you press the power button, you’ll see a
keypad instead of the padlock icon. To unlock your phone, enter your PIN and
touch Enter at the bottom-right of the keypad.
If you prefer, you can alternatively set a pattern code, or
use an alpha-numeric password. The Moto G even offers a Face Unlock feature,
but we don't recommend using it as it's not as secure, and also means your
family can't unlock and use your phone.
How to use Android: Import Contacts from your Old Phone
There are easier ways of getting all your contacts into your
new phone than typing them all in from scratch. Here we’ll show you how to do
it if your old phone is non-Android although there are other options available
if you’re migrating from another Android device.
Your old phone should provide some means of exporting
contacts, even if it's simply copying names and numbers - those stored in the
phone's memory - onto the SIM card. You can then put the SIM card into your new
phone (if it doesn't fit, here's how to cut it down) and import the contacts.
Your old phone may have a way of synching or uploading its
stored contacts to a PC. Generally they’ll appear on your PC as either a comma
delimited file (.csv) or as one or more VCard files (.vcf). Google Play lists
several apps from importing contacts from .csv or .vcf files and you could try
these.
However, your Google account provides another option. Before
starting, though, if your contacts are stored on your PC as lots of .vcf files,
one per contact, you first need to combine them into a single file. To do this,
start the command line interpreter (Cmd in the Start Menu’s Search box), and go
to the folder in which your .cvf files are stored by typing, for example, ‘cd
\phone\contacts’. Now type ‘copy /b *.vcf merged.vcf’ to create a single file
containing all your contacts.
Now, log into google.com/contacts, select import contacts
and provide the name of your .csv or merged .vcf file. Next time your phone
synchronises, those contacts will automatically become available on your phone.
Alternatively, you can make your phone synchronise immediately in the Settings
app under ‘Accounts’, ‘Google’.
How to use Android: Beginner's guide to Android
Here we continue our guide to Android 4.4 KitKat, using a
Motorola Moto G.
How to use Android: Make a Phone Call
To make a phone call, tap the telephone handset icon that
will be visible near the bottom left of your home screen. If you want to call
someone in your address book, touch ‘All contacts’, scroll down to find the
person you want to talk to and select that name.
Alternatively, to dial someone who’s not in your address
book, after tapping the telephone icon, select the keypad icon in the middle at
the bottom. Now type the number and touch the telephone handset icon in the bar
at the bottom. Whichever method you choose to initiate a call, to end it just
touch the red telephone handset icon.
How to use Android: Send a Text Message
To send a text message, touch the Messaging icon which is
the square green smiley face at the bottom of your home page. Initially no
conversations will be display so tap the icon at the bottom left that looks
like a piece of paper with a plus sign.
A blank message and a QWERTY keyboard will appear – rotate
the screen through ninety degrees if you want a larger keyboard.
Initially the cursor will be in the ‘To’ area so start
typing a name and all the contacts in your address book that start what you’ve
typed so far will be shown. Make your choice by touching the appropriate
contact.
Add other contacts in just the same way if you want. Now
type your message, tapping on ‘Send’ when you’re done.
How to use Android: Select, Edit, Copy and Paste
Just as selecting, editing, copying and pasting text are
invaluable techniques on a PC, these are also actions that you’ll find useful
in Android. To make a selection, touch the text for a second and a word will be
highlighted in blue. To change the selection, drag the blue pointers at the
start and end to highlight more or less text. Whenever text is selected on
screen, the copy icon (two pieces of paper) will appear – tap it to copy the
selection text to the clipboard.
If you’re in an application where editing is permitted, for
example while composing a text or email, several other options are available.
For a start, when you select text, in addition to copying you can cut the
selected text using the cut icon (a piece of paper and scissors) or replace it
with the text in the clipboard using the paste icon (a clipboard). In addition,
if you only touch the text briefly the cursor will appear at that point (and
you can move it using the blue pointer), allowing you to insert text from the
keyboard, or the clipboard, or delete text.
How to use Android: Take a Photo
The Moto G has a both a main and a front-facing camera, but
the process is virtually the same with all Android phones. Some, though, have a
dedicated camera button which launches the app and can be used to take photos
or videos.
If there's no such button, such as on the Moto G, touch the
camera icon at the bottom-right corner of the home screen. The screen will show
a preview and tapping anywhere on the screen will take a photo. Alternatively,
to capture a video, touch the video camera icon at the bottom right. Recording
will start and a timer will appear at the top left. To stop recording press the
icon at the bottom right that will have changed to a square in a circle.
To see your photos and videos while in the camera app, touch
the right hand edge of the screen and drag to the left. Swipe left and right to
move between your photos and/or videos, touching a video if you want to play
it. The camera also has various options that you can select by dragging right
from the left hand edge of the screen. We’ll leave you to try these out. You
can view your photos later using the Gallery app
