- 2. Objectives Define Android Enumerate Android Versions Identify tools in Android Development State components in Eclipse Run Android Application in Emulator
- 4. What is Android? o Open mobile platform by Google o Defined as Software Stack for mobiles o Start of Open Handset Alliance o Maintained by Android Open Source Project o Brought from Danger Inc. by Google
- 6. Android Version Market Share
- 7. What will you need?
- 10. 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
- 11. Activities
- 12. 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
- 14. XML • Used to define some of the resources o Layouts (UI) o Strings • Manifest file • Shouldn’t usually have to edit it directly, Eclipse can do that for you • Preferred way of creating UIs o Separates the description of the layout from any actual code that controls it o Can easily take a UI from one platform to another
- 15. 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 resources
- 16. Layouts • Eclipse has a great UI creator o Generates the XML for you • Composed of View objects • Can be specified for portrait and landscape mode o Use same file name, so can make completely different UIs for the orientations without modifying any code
- 17. 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 emulator o Otherwise, it should be smart and use whichever one is available
