7. SETUP
 Download the Android SDK.
 Install the ADT plugin for Eclipse (if you’ll use the
Eclipse IDE).
 Download the latest SDK tools and platforms using
the SDK Manager.

11. Activity
An Activity is an application component that provides
a screen with which users can interact in order to do
something, such as dial the phone, take a
photo, send an email. Each activity is gives a window
in which to draw its user interface.
An Application usually consists of multiple activities
that are loosely bounded to each other.

13. CREATING A PROJECT
13

14. PROJECT COMPONENTS
 src – your source code
 gen – auto-generated code (usually just
R.java)
 Included libraries
 Resources
 Drawables (like .png images)
 Layouts
 Values (like strings)
 Manifest file 14

15. XML
 Used to define some of the resources
 Layouts (UI)
 Strings
 Manifest file
 Shouldn’t usually have to edit it
directly, Eclipse can do that for you
 Preferred way of creating UIs
 Separates the description of the layout
from any actual code that controls it
 Can easily take a UI from one platform to
another 15

16. R CLASS
 Auto-generated: you shouldn’t edit it
 Contains IDs of the project resources
 Enforces good software engineering
 Use findViewById and Resources object to
get access to the resources
 Ex. Button b =
(Button)findViewById(R.id.button1)
 Ex.
getResources().getString(R.string.hello));
16

17. LISTVIEW
ListView is a view group that displays a list of scrollable items.
17

18. INTENT
Intent are asynchronous messages which allow application
components to request functionality from other Android
components. Intents allow you to interact with components from
the own and other applications. For example an activity can start
an external activity for taking a picture.
Ex. Intent in=new Intent(Act.this,Klm.class);
startActivity();
current
class
reference
new
Activity

20. SHAREDPREFERENCES
For any particular set of preferences, there is a single instance of this
class that all clients share. Modifications to the preferences must go
through an SharedPreferences.Editor object to ensure the preference
values remain in a consistent state and control when they are committed
to storage.

21. ABOUT SQLITE
 SQLite is an embedded SQL database engine.
 SQLite does not have a separate server process.
 SQLite reads and writes directly to ordinary disk files.
21

22. SQLITE DATABASE
 SQLiteDatabase has methods to create, delete, execute SQL
commands, and perform other common database
management tasks.
 Database names must be unique within an application, not
across all applications.
