4. Future of Android
• Android is a mobile phone operating system powered by
Google
• Nearly every device in your house, from your television to
your refrigerator, is going to be networked and could very well
be Android-powered”, says Google Chairman Eric Schmidt
• Android had a worldwide smart-phone market share of 75%
by the third quarter of 2012, with 500 million devices
activated in total and 1.3 million activations per day

9. What is Android
 Open software platform for mobile development
 A complete stack – OS, Middleware, Applications
 An Open Handset Alliance (OHA) project
 Powered by Linux operating system
 Fast application development in Java
 Open source under the Apache 2 license

12. Application Building Blocks
 Activity
 IntentReceiver
 Service
 ContentProvider
TSCS (The School of Creative Sciences)

13. Activities
 Typically correspond to one UI screen
 But, they can:
 Be faceless
 Be in a floating window
 Return a value
 Activity refers to (J)Frame in Swing
TSCS (The School of Creative Sciences)

14. Intents
 Think of Intents as a verb and object; a description of what
you want done
 E.g. VIEW, CALL, PLAY etc.
 System matches Intent with Activity that can best provide the
service
 Activities and IntentReceivers describe what Intents they can
service
TSCS (The School of Creative Sciences)

15. Intent Receivers
 Components that respond to broadcast ‘Intents’
 Way to respond to external notification or alarms
 Apps can invent and broadcast their own Intent
TSCS (The School of Creative Sciences)

16. Services
 Faceless components that run in the background
 E.g. music player, network download etc…
TSCS (The School of Creative Sciences)

17. Content Providers
 Enables sharing of data across applications
 E.g. address book, photo gallery
 Provides uniform APIs for:
 querying
 delete, update and insert.
 Content is represented by URI and MIME type
TSCS (The School of Creative Sciences)

18. DIFFERENT LAYOUTS HIERARCHY OF SCREEN ELEMENTS
Linear Layout
Absolute Layout
Table Layout
ANDROID USER INTERFACES
TSCS (The School of Creative Sciences)

19. Activities in Android refers almost to a (J)Frame in Swing
Views in Android refers to (J)Components in Swing
TextViews in Android refers to a (J)Labels in Swing
EditTexts in Android refers to a (J)TextFields in Swing
Buttons in Android refers to a (J)Buttons in Swing
COMPARING ANDROID UI ELEMENTS TO SWING
UI ELEMENTS
TSCS (The School of Creative Sciences)

20. <application>
Root element containing declarations of the application-level components contained in the
package. This element can also include global and/or default attributes for the application,
such as a label, icon,theme, required permission, etc.Quantity: 0 or 1.
<activity>
An Activity is the primary thing for an application to interact with the user. The initial screen the
user sees when launching an application is an activity, and most other screens they use will be
implemented as separate activities declared with additional activity tags.
<intent-filter>
Declares what kind of Intents a component supports. In addition to the various kinds of
values that can be specified under this element, attributes can be given here to supply a
unique label, icon, and other information for the action being described.
TSCS (The School of Creative Sciences)

21. <action>
An action-type that the component supports. Example:
<category>
A category-type that the component supports. Example:
Some other Tags Available……
<meta-data>
<receiver>
<service>
<provider>

22.  Download and Install the
Android SDK and Test the
Emulator
 Installing JDK and JRE(1.5 or
above)
 Install Eclipse
 Install ADT plugin for Eclipse

30. Porting Applications to Mobile
 Resource files are bundled to .apk file archive
 Bundled by aapt tool
 One .apk file archive is a Single application
TSCS (The School of Creative Sciences)

31. Interesting things to do
 Android is open source
 Opportunities for researchers
 Get the source, compile and update the device image
