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

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

Application Building Blocks Activity

IntentReceiver

Service

ContentProvider


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


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


Intent Receivers Components that respond to broadcast ‘Intents’

Way to respond to external notification or alarms

Apps can invent and broadcast their own Intent


Services Faceless components that run in the background

E.g. music player, network download etc…


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


ANDROID USER INTERFACES

DIFFERENT LAYOUTSLinear Layout

HIERARCHY OF SCREEN ELEMENTS


COMPARING ANDROID UI ELEMENTS TO SWING UI ELEMENTS

Activities in Android refers almost to a (J)Frame in SwingViews in Android refers to (J)Components in SwingTextViews in Android refers to a (J)Labels in Swing EditTexts in Android refers to a (J)TextFields in SwingButtons in Android refers to a (J)Buttons in Swing


<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.


<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>


APPLICATION DEVELOPMENT STEPS

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


APPLICATION DEVELOPMENT CNTD.

New > Project…

Select Android project in wizard menu



Main Activity>>

Main.xml>>



AndroidManifest.xml>>



>>Running Your First Application



Output in the emulator



UIs using Java way


Porting Applications to Mobile Resource files are bundled to .apk file archive

Bundled by aapt tool

One .apk file archive is a Single application


Interesting things to do Android is open source

Opportunities for researchers

Get the source, compile and update the device image
