For example, An activity might present a list of menu items; Or shows a list of contacts to send messages to Work together to form a cohesive user interface Each activity is independent of the others. Can communicate together One of the activities is marked as the first one Moving from one activity to another is accomplished by having the current activity start the next one. An activity can also make use of additional windows. For example, A pop-up dialog that calls for a user response in the midst of the activity. A view hierarchy is placed within an activity's window by theActivity.setContentView() method. The content view is the Viewobject at the root of the hierarchy.Android, a Linux-based Mobile Phone Operating System Android, a Linux-based Mobile Phone Operating System 6 7. 6/30/09 Layout & View Service res/layout/main.xml Doesn't have a visual user interface Runs in the background for an indefinite period of time. Keep the music playback service running even after the activity that Exposed by the service. E.g., interface allows pause, rewind, stop, and restart the playback. Android, a Linux-based Mobile Phone Operating SystemAndroid, a Linux-based Mobile Phone Operating System Life cycleBroadcastReceiver Does nothing but receive and react to announcements. Many broadcasts from the system, timezone has changed battery is low, picture has been taken, or that the user changed a language preference. Applications can also initiate broadcasts Data has been downloaded, etc. An application can have any number of broadcast receivers Receivers extend the BroadcastReceiver base class. Broadcast receivers do not display a user interface. May start an activity in response May use the NotificationManager to alert the user Flashing the backlight, vibrating the device, etc. Place a persistent icon in the status bar Android, a Linux-based Mobile Phone Operating SystemAndroid, a Linux-based Mobile Phone Operating System 7 8. 6/30/09 ContentProviderIntent Make application data available to other applications. Activities, services, and broadcast receivers are activated through intents. Can be stored in the file system, Facility for late run-time binding between components In an SQLite database, Passive data structure holding an abstract description of an operation to beperformed Or in any other manner that makes sense. To launch or get an activity, an Intent object is passed to Implementa standard set of methods Context.startActivity(), Activity.startActivityForResult() Context.startService() to initiate a service Enables other applications to retrieve and store data Context.bindService() to establish a connection Applications do not call methods directly broadcast methods Context.sendBroadcast(), Context.sendOrderedBroadcast(), ContentResolver object is used Context.sendStickyBroadcast()) Can talk to any content provider System finds the appropriate activity, service, or set of broadcast receivers Cooperates with the provider to manage any interprocess Intent passed to startActivity() is delivered only to an activity, never to a service communication that's involved. or broadcast receiver, etc.Android, a Linux-based Mobile Phone Operating System Android, a Linux-based Mobile Phone Operating System Activity, Intent, and ServiceRPC Android, a Linux-based Mobile Phone Operating System Android, a Linux-based Mobile Phone Operating System8 9. 6/30/09 From Source to Deployment WhychoosingAndroid ?Android, a Linux-based Mobile Phone Operating System Android, a Linux-based Mobile Phone Operating System Im freeIm openAndroid, a Linux-based Mobile Phone Operating System Android, a Linux-based Mobile Phone Operating System9 10. 6/30/09 Android Perspectives Im a communityAndroid, a Linux-based Mobile Phone Operating System Android, a Linux-based Mobile Phone Operating System Android on the phone marketAndroid on other markets Moreand more handset manufactures are choosing Androidis already used on Android Tablet PC To compete with the iPHONE HP Is 'Studying' Android for PC Use Android Eee PCs are also announced Anychance of success ?
