14. Refined, Evolved UI
Beyond Smart
Your Android device is already smart, and it’s only
going to get smarter. Android was the first to bring you
features on certain devices like Face Unlock — which
uses facial recognition to let you unlock your device
with a smile,
Android Beam —
which lets you share contacts, directions and more by
touching two devices together, and Google Now —
which brings you just the right information, before you
even ask.

15. WIDGETS
 Put the important stuff
right within reach and
interact with your
favorite apps directly
from your home screen
with widgets — see the
latest sport scores, view
your favorite photos,
check the weather or
peek at your inbox all
without having to open
different apps or leave
the home screen.

16. Notifications
 An easy-to-read notification tray gives
you quick access to your calls, incoming
texts, and new emails in a non-intrusive
way.

17. Multi-Tasking
 With Android, you can quickly and
seamlessly switch between apps and pick
up whatever you were doing. Juggling
multiple tasks at once on a mobile device
has never been easier.

18. Voice Typing & Action
 Control your Android device with your
voice. Simply touch the microphone on
the keyboard and start talking to write
emails, SMS, or any other text — more
than 30 languages supported. Text
appears in real time, so there’s no waiting.

19. Photos & Videos
 Capture special moments with great
photos and videos, explore your shots and
quickly share your favourites in any way
that you want.

20. Conclusion
 Android development is based on Java
programming. A person has to be a good
Java programmer to learn Android
application development.
 Android applications doesn't get
developed in a day or two, it requires lots
of practice and hard work.
