Android Development Tool

Application Components

Activity - java class that extends Activity

Services - runs in background for period of time

Broadcast Receivers - receives and react to broadcast announcement

Content Providers - store and retrieve data for all applications

Intents - the intention of an action

Activities

Services

• Run in the background

• Can be bound to an application

• Needs to be declared in manifest file

• Like Activities, has a structured life cycle

Project Components

XML

• Used to define some of the resourceso Layouts (UI)o Strings

• Manifest file

• Shouldn’t usually have to edit it directly, Eclipse can do that for you

• Preferred way of creating UIso Separates the description of the layout from any

actual code that controls ito Can easily take a UI from one platform to another

R Class

• Auto-generated: you shouldn’t edit it

• Contains IDs of the project resources

• Enforces good software engineering

• Use findViewById object to access the resourceso Ex. Button b = (Button)findViewById(R.id.button1)

Layouts

• Eclipse has a great UI creatoro Generates the XML for you

• Composed of View objects

• Can be specified for portrait and landscape modeo Use same file name, so can make completely different

UIs for the orientations without modifying any code

Running in Eclipse

• Similar to launching a regular Java app, use the launch configurations

• Specify an Android Application and create a new one

• Specify activity to be run

• Can select a manual option, so each time program is run, you are asked whether you want to use the actual phone or the emulatoro Otherwise, it should be smart and use whichever one

is available
