2.  Android is a Linux-based operating system
for mobile devices such as Smartphone's
and tablet computers.
 It is currently the most used OS in today's
Smartphone's and Tablet’s.
 It is an open source OS which is what makes
it to fully harness it’s capability to its fullest.
 It is owed by Google.

4.  Application framework enabling reuse and replacement of components
 Dalvik virtual machine optimized for mobile devices
 Integrated browser based on the open source WebKit engine
 Optimized graphics powered by a custom 2D graphics library; 3D graphics based on
the OpenGL ES 1.0 specification (hardware acceleration optional)
 SQLite for structured data storage
 Media support for common audio, video, and still image formats
(MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, GIF)
 GSM Telephony (hardware dependent)
 Bluetooth, EDGE, 3G, and WiFi (hardware dependent)
 Camera, GPS, compass, and accelerometer (hardware dependent)
 Rich development environment including a device emulator, tools for
debugging, memory and performance profiling, and a plugin for the Eclipse IDE

5.  Android is a open development platform.
 Android offers developers the ability to
build extremely rich and innovative
applications.
 Developers are free to take advantage of
the device hardware, access location
information, run background services, set
alarms, add notifications to the status
bar, and much, much more.

6.  Developers have full access to the same
framework APIs used by the core
applications.
 The application architecture is designed to
simplify the reuse of components; any
application can publish its capabilities and
any other application may then make use
of those capabilities (subject to security
constraints enforced by the framework). This
same mechanism allows components to be
replaced by the user.

7. Android has seen a number of updates since its original release, each fixing bugs and adding
new features. Each version is named, in alphabetical order, after a dessert.
 2.3 Gingerbread refined the user interface, improved the soft keyboard and copy/paste
features, better native code support (which improves gaming performance), added SIP
support (VoIP calls), and added support for Near Field Communication.
 3.0 Honeycomb was a tablet-oriented release which supports larger screen devices and
introduces many new user interface features, support for multi-core processors, hardware
acceleration for graphics and full system encryption.
 3.1 Honeycomb, released in May 2011, added support for extra input devices, USB host mode
for transferring information directly from cameras and other devices, and the Google Movies
and Books apps.
 3.2 Honeycomb, released in July 2011, added optimization for a broader range of screen
sizes, new "zoom-to-fill" screen compatibility mode, loading media files directly from SD
card, and an extended screen support API.
 4.0 Ice Cream Sandwich, announced on October 19, 2011, brought Honeycomb features to
Smartphone's and added new features including facial recognition unlock, network data
usage monitoring and control, unified social networking contacts, photography
enhancements, offline email searching, app folders, and information sharing using NFC.
Android 4.0.4 is the latest Android version that is available to phones.

8.  Up to today there is only one company
who has given an Android a tough
competition and you might be aware of
that.
 And yes!! What you are thinking is right ?
Apple iOS is the only OS which has given
Android a tough Competition.
 Android and iOS together compromise of
95% of the total OS currently used in
Smartphone’s and Tablet’s.

9.  Other OS are also available in the market but they
are not as famous and efficient as Android and iOS.
 To name a few such as –
i. Symbian OS which is used in Nokia Smartphone’s .
ii. BlackBerry OS for BlackBerry Phones and Tablets.
iii. Windows OS which is also used in Nokia
Smartphone’s as well as in some other phone’s too.

10.  Sometimes people do get confuse in term of
comparing Android with Apple.
 What they forget is that Android is just an OS
which is used in various Smartphone’s and
Tablet’s but an iPhone is a device
(hardware)which has iOS as Operating System
so comparing an iPhone with Android is
baseless.
 And so the power of Android OS depend on
the configuration of the Smartphone’s and
Tablet’s as well.

13.  A tablet is a device which is in between the
Smartphone and laptop.
 Which mean it should be more powerful
than a Smartphone and more portable
then a Laptop.

14.  Now days tablet is more used then a
laptop.
 Due to its portability it is easy to carry a
tablet then a laptop.
 And due to emerging of more powerful
and portable tablet , it has fill the space
between laptop and Smartphone very
efficiently.

15.  With the booming business in field of
tablets there are variety of tablets
available in market.
 Ranging from iPad(Apple) to
Playbook(Blackberry) to a large number
of Android tablet available in the
Market.

16.  Google Play is an online software store developed by Google for Android
devices. An application program ("app") called "Play Store" is preinstalled on
most Android devices and allows users to browse and download apps
published by third-party developers, hosted on Google Play. As of October
2011, there were more than 500,000 apps available for Android, and the
estimated number of applications downloaded from the Play Store as of
December 2011 exceeded 10 billion. The operating system itself is installed on
130 million total devices.
 Only devices that comply with Google's compatibility requirements are
allowed to preinstall and access the Play Store .The app filters the list of
available applications to those that are compatible with the user's
device, and developers may restrict their applications to particular carriers or
countries for business reasons.
 Google has participated in the Play Store by offering many free applications
themselves, including Google Voice, Google Goggles, Gesture
Search, Google Translate, Google Shopper, Listen and My Tracks. In August
2010, Google launched "Voice Actions for Android", which allows users to
search, write messages, and initiate calls by voice.

19.  Android has more dependable features that iOS fails to
bring to their consumers.
 For one thing, Android is an open source platform. Users
are able to customize it according to their own
convenience.(If you know Android Programming)
 Android products are way cheaper than iOS.
 There are many Android platform devices to choose from.
 A large number of paid app in App Store (of apple iOS) are
free for android(in Google Play).

20.  Android allows any app to run on their platform. The
iOS platform apps are only limited to those that are
available in the App Store and nothing else.
 You can make your own theme and install it in cell
phone. The iOS however, cannot give you this
feature. Themes an options that iOS has to offer are
very limited.
 Devices with the Android platform have more
hardware choices. You can configure hardware on
Android and in the iOS, you cannot.
