The document discusses an introduction to Android development. It covers topics like what Android is, its features, architecture, and how to set up the Android Development Tools (ADT) plugin for Eclipse. It describes Android applications and their fundamental components like activities, services, broadcast receivers, and content providers. It also explains how to start an activity and work with views and view groups to define a user interface.

7. Working with Android
Development Tools (ADT)
 The Android Development Tools (ADT) plugin
for Eclipse adds powerful extensions to the
Eclipse integrated development environment.

It gives you access to other Android development
tools from inside the Eclipse IDE.

It provides a New Project Wizard It automates and
simplifies the process of building your Android
application.

It provides an Android code editor that helps you write
valid XML for your Android manifest and resource
files.

It will even export your project into a signed APK,
which can be distributed to users.

10. Application Fundamentals
 Applications are written using Java
 The Android Asset Packaging Tool
generates apk (Android Package) files
containing the code and any data and
resources needed
 Each application runs in its own Linux
process
 Each application has its own VM
 Each application has its own user id,
permissions are set accordingly
PROF. ERWIN M. GLOBIO, MSIT

11. Application Components
 A central feature of Android is that one
application can make use of elements of
other applications (provided those
applications permit it)
 Android applications don't have a single
entry point for everything in the application
(no main() function, for example)
 They have essential components that the
system can instantiate and run as needed
PROF. ERWIN M. GLOBIO, MSIT

12. Application Components
 Activities - An activity presents a visual user interface
for one focused endeavor the user can undertake.
 Services - A service doesn't have a visual user
interface, but rather runs in the background for an
indefinite period of time.
 Broadcast Receivers - A broadcast receiver is a
component that does nothing but receive and react to
broadcast announcements
 Content Providers - A content provider makes a
specific set of the application's data available to other
applications. The data can be stored in the file system, in
an SQLite database, or in any other manner that makes
sense.
 Intent - An intent is an Intent object that holds the
content of the message
PROF. ERWIN M. GLOBIO, MSIT

13. Starting with an Activity
 The main starting point of most applications
 There is no concept of “main” program
 Each activity can be executed or invoked at any
time
 One application can have multiple “activities”
 An example of activity would be “Searching for
an application in the store”
 An Activity can have several “Views” or “View
Groups” to define its user inteface.
