1.app - API Demos / 실행사진, 소스 추가 (2010/06/11)
Activity 액티비티
- Hello World
- Demonstrates a basic screen activity.
- Code:
- HelloWorld.java
- Layout:
- hello_world.xml
- Save & Restore State
- Demonstrates how an activity should save state when it is paused.
- Persistent State
- Demonstrates how you can save and restore preferences, which are stored even after the user closes the application.
- Receive Result
- Demonstrates how an activity screen can return a result to the activity that opened it.
- Forwarding
- Demonstrates opening a new activity and removing the current activity from the history stack, so that when the user later presses BACK they will not see the intermediate activity.
- Redirection
- Demonstrates how to save data to preferences and use it to determine which activity to open next.
Translucent / 실행시 밑에 내용이 안보이게
- Demonstrates how to make an activity with a transparent background.
- TranslucentBlur // 실행시 밑에 내용이 약간 보이게..
- Demonstrates how to make an activity with a transparent background with a special effect (blur).
Service 서비스
- Local Service Controller
- Starts and stops the service class LocalService that runs in the same process as the activity, to demonstrate a service's lifecycle when using {@link android.content.Context#startService Context.startService} and {@link android.content.Context#stopService Context.stopService}.
- Local Service Binding
- Demonstrates binding to a service class LocalService that runs in the same process as the activity, to demonstrate using the {@link android.content.Context#bindService Context.bindService} and {@link android.content.Context#unbindService Context.unindService} methods with a service. This also shows how you can simplify working with a service when you know it will only run in your own process.
- Remote Service Controller
- Demonstrates starting a service in a separate process, by assigning
android:process=":remote" to the service in the AndroidManifest.xml file. - Remote Service Binding
- Demonstrates binding to a remote service, similar to the Local Service Binding sample, but illustrating the additional work (defining aidl interfaces) needed to interact with a service in another process. Also shows how a service can publish multiple interfaces and implement callbacks to its clients.
- Service Start Arguments Controller
- Demonstrates how you can use a Service as a job queue, where you submit jobs to it with {@link android.content.Context#startService Context.startService} instead of binding to the service. Such a service automatically stops itself once all jobs have been processed. This can be a very convenient way to interact with a service when you do not need a result back from it.
- Code:
- ServiceStartArgumentsController.java
- ServiceStartArguments.java
- Layout:
- service_start_arguments_controller.xml
- Foreground Service Controller
- Controls the service class ForegroundService, which shows how you can write a Service that runs in the foreground and works on both pre-2.0 and post-2.0 versions of the platform. This example will selectively use the new foreground APIs that were introduced in Android 2.0 if they are available.
Alarm 알람 - sleep상태에서도 작동하게 해주는....
- Alarm Controller
- Demonstrates two ways you can schedule alarms: a one-shot alarm that will happen once at a given time, and a repeating alarm that will happen first at a given time and then continually trigger at regular intervals after that.
- Code:
- AlarmController.java
- OneShotAlarm.java
- RepeatingAlarm.java
- Layout:
- alarm_controller.xml
- Alarm Service
- Demonstrates how you can schedule an alarm that causes a service to be started. This is useful when you want to schedule alarms that initiate long-running operations, such as retrieving recent e-mails.
- Code:
- AlarmService.java
- AlarmService_Service.java
- Layout:
- alarm_service.xml
Notification 공지 노티
- NotifyWithText

- IncomingMessage
- Demonstrates sending persistent and transient notifications, with a View object in the notification. It also demonstrated inflating a View object from an XML layout resource.

- Demonstrates an activity that receives Search intents and handles them.
- SearchSuggestionSampleProvider

- Layout:
- hello_world.xml
- PolyToPoly
- Demonstrates calling the {@link android.graphics.Matrix.html#setPolyToPoly(float[],int,float[],int,int)} method to translate coordinates on a canvas to a new perspective (used to simulate perspective).

- Demonstrates using the {@link android.graphics.Paint} and {@link android.graphics.Canvas} objects to draw random points on the screen, with different colors and strokes.
- PathEffects
