6. Why Android
 Since in the today’s marketing system
of smart phones , 81%of the users are
using android mobile operating system
and 15% -apple and 4%-windows .
 Besides the technicians of various other
companies are also joining OHA ,since
they don’t have their own Operating
System.
 Gradually one day Android Operating
System only will work on all the smart
phones.

7. Android Life cycle
 If an activity is paused or stopped, the system
can drop it from memory either by asking it
to finish(calling its finish() method) or simply
killing its process.
 When it is displayed again to the user, it must
be completely restarted or restored to its
previous state.
 As an activity transactions from state to state.
It is notified if the change by calls to the
following protected transmission methods.
 Void onCreate(Bundle savedInstanceState),
onStart(), onRestart(), onResume(), onPause(),
onStop(), onDestroy().

8. Project:- E-Store
 In this E-Store app, we can purchase
the goods simply by sitting in our
home.
The different categories of goods
available are :
 Clothing
 Electronics and
 Books
Benefits Of E-Store:-
 Convenience.
 Better prices.
 More variety:
 You can send gifts more easily.
 Fewer expenses.
 Price comparisons.
 No crowds.

9. Different kinds of files in Android:
 AndroidManifest.xml file:
 R.Java file:
 APK file:
 MainLayout.xml file:
 JAR file:-
About .dex files and benefits:-
 Android programs are compiled into .dex (Dalvik
Executable) files, which are in turn zipped into a
single .apk file on the device.
 Dex file is a class in Java. This class is similar in
principle to Zip File.
 Due to its light weighted nature, it is implemented in
Android Applications.

10. Layouts
A layout defines the visual structure for a user interface, such as the UI for an activity of an app.
Different kinds of layouts are:-
Linear Layout:- A layout
that organizes its children into
a single horizontal or vertical
row. It creates a scrollbar if the
length of the window exceeds
the length of the screen.

11.  Relative Layout:-Enables
you to specify the location of
child objects relative to each
other (child A to the left of child
B) or to the parent (aligned to
top of the parent).

12. on Create() function:-
 onCreate(Bundle) is where you initialize your activity. When Activity is started and
application is not loaded, then both onCreate() methods will be called.
 Generally for C,C++ or Java language the execution of the program starts from the
main() function . But in Android , there exists no such main() function. The execution of
the program in Android starts with onCreate() function.
Syntax:-
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

13. Intents:
Android Intent is the message that is passed between components such as activities, content
providers, broadcast receivers, services etc.
Android intents are mainly used to:
 Start the service
 Launch an activity
 Display a web page
 Display a list of contacts
 Broadcast a message
 Dial a phone call etc.

14. Sqlite Database
 SQLite is an open-source relational database i.e. used to perform database
operations on android devices such as storing, manipulating or retrieving persistent
data from the database.
 It is embedded in android bydefault. So, there is no need to perform any database
setup or administration task.
 SQLiteOpenHelper class provides the functionality to use the SQLite database.
 SQLiteDatabase class:
It contains methods to be performed on sqlite database such as create, update,
delete, select etc.
