•Android is an open source and Linux-based Operating System for cell
phones, for example, cell phones and tablet PCs. Android was created
by the Open Handset Alliance, drove by Google, and different
organizations.

3. Android offers a brought together way to deal with application
improvement for cell phones which implies engineers require
create for Android, and their applications ought to have the
capacity to keep running on various gadgets controlled by
Android.
Android Applications:-
Android applications are normally created in the Java dialect
utilizing the Android Software Development Kit.
Once created, Android applications can be bundled effortlessly
and sold out either through a store, for example, Google Play,
SlideME, Opera Mobile Store, Mobango, F-droid and the

MP3, MIDI, Ogg Vorbis, WAV, JPEG, PNG, GIF, and BMP.
5.Messaging:
SMS and MMS

6. 6.Web program:
In light of the open-source WebKit design motor, combined with
Chrome's V8 JavaScript motor supporting HTML5 and CSS3.
7.Multi-touch:
Android has local help for multi-touch which was at first made
accessible in handsets, for example, the HTC Hero.
8.Multi-entrusting:
Client can hop starting with one undertaking then onto the next and same
time different application can run at the same time.
9.Resizable gadgets:
Gadgets are resizable, so clients can grow them to demonstrate more
substance or psychologist them to spare space.
10.Multi-Language:
Backings single course and bi-directional content.

7. 11.GCM:
Google Cloud Messaging (GCM) is an administration that gives
engineers a chance to send short message information to their
clients on Android gadgets, without requiring a restrictive
synchronize arrangement.
12.Wi-Fi Direct:
An innovation that lets applications find and combine
straightforwardly, finished a high-transmission capacity distributed
association.
13.Android Beam:
A prevalent NFC-based innovation that lets clients in a split second
offer, just by touching two NFC-empowered telephones together.

8. Set-up Java Development Kit (JDK):-
•You can download the most recent rendition of Java JDK from
Oracle's Java website − Java SE Downloads. You will discover
directions for introducing JDK in downloaded documents, take after
the offered guidelines to introduce and arrange the setup.
•At last set PATH and JAVA_HOME condition factors to allude to
the catalog that contains java and javac, commonly
java_install_dir/receptacle and java_install_dir individually.
Android IDEs:-
There are such a large number of refined Technologies are accessible
to create android applications, the recognizable advancements,
which are dominatingly utilizing devices as takes after
1.Android Studio
2.Obscuration IDE(Deprecated)

9. Architecture:-

10. Android Libraries:-
•This class includes those Java-based libraries that are particular to
Android improvement. Cases of libraries in this class incorporate
the application system libraries notwithstanding those that
encourage UI building, designs drawing and database get to. A
rundown of some key center Android libraries accessible to the
Android engineer is as per the following −
•android.app − Provides access to the application demonstrate and
is the foundation of all Android applications.
•android.content − Facilitates content access, distributing and
informing amongst applications and application parts.

11. •android.database − Used to get to information distributed by
content suppliers and incorporates SQLite database administration
classes.
•android.opengl − A Java interface to the OpenGL ES 3D
illustrations rendering API.
•android.os − Provides applications with access to standard
working framework administrations including messages,
framework benefits and between process correspondence.
•android.text − Used to render and control message on a gadget
show.
•android.view − The key building squares of utilization UIs.

12. android.widget − A rich accumulation of pre-manufactured UI segments,
for example, catches, marks, list sees, design administrators, radio
catches and so on.
android.webkit − An arrangement of classes planned to permit web-
perusing capacities to be incorporated with applications.
Having secured the Java-based center libraries in the Android runtime, it
is currently time to turn our consideration regarding the C/C++ based
libraries contained in this layer of the Android programming stack.
Android Runtime :-
This is the third segment of the design and accessible on the second layer
from the base. This segment gives a key part called Dalvik Virtual
Machine which is a sort of Java Virtual Machine uncommonly outlined
and improved for Android.

13. •The Dalvik VM influences utilization of Linux to center
highlights like memory administration and multi-threading,
which is inherent in the Java dialect. The Dalvik VM
empowers each Android application to keep running in its own
particular procedure, with its own case of the Dalvik virtual
machine.
•The Android runtime likewise gives an arrangement of center
libraries which empower Android application designers to
compose Android applications utilizing standard Java
programming dialect.
Application Framework:-
•The Application Framework layer gives numerous larger
amount administrations to applications as Java classes.
Application engineers are permitted to make utilization of
these administrations in their applications.

14. •The Android system incorporates the accompanying key
administrations −
•Action Manager − Controls all parts of the application lifecycle
and movement stack.
•Content Providers − Allows applications to distribute and share
information with different applications.
•Asset Manager − Provides access to non-code installed assets,
for example, strings, shading settings and UI designs.
•Warnings Manager − Allows applications to show cautions and
notices to the client.
•View System − An extensible arrangement of perspectives used
to make application UIs.

15. Applications:-
•You will discover all the Android application at the best
layer. You will compose your application to be
introduced on this layer as it were. Cases of such
applications are Contacts Books, Browser, Games and so
forth.
•Application segments are the basic building pieces of an
Android application. These parts are approximately
coupled by the application show record
AndroidManifest.xml that depicts every segment of the
application and how they cooperate.
