Class Overview

The AlarmClock provider contains an Intent action and extras that can be used to start an Activity to set a new alarm or timer in an alarm clock application. Applications that wish to receive the ACTION_SET_ALARM and ACTION_SET_TIMER Intents should create an activity to handle the Intent that requires the permission com.android.alarm.permission.SET_ALARM. Applications that wish to create a new alarm or timer should use Context.startActivity() so that the user has the option of choosing which alarm clock application to use.

Constants

public static final String ACTION_SET_ALARM

Added in API level 9

Activity Action: Set an alarm.

Activates an existing alarm or creates a new one.

This action requests an alarm to be set for a given time of day. If no time of day is specified, an implementation should start an activity that is capable of setting an alarm ( EXTRA_SKIP_UI is ignored in this case). If a time of day is specified, and EXTRA_SKIP_UI is true , and the alarm is not repeating, the implementation should remove this alarm after it has been dismissed. If an identical alarm exists matching all parameters, the implementation may re-use it instead of creating a new one (in this case, the alarm should not be removed after dismissal). This action always enables the alarm.

Request parameters

Constant Value: "android.intent.action.SET_ALARM"

public static final String ACTION_SET_TIMER

Activity Action: Set a timer.

Activates an existing timer or creates a new one.

This action requests a timer to be started for a specific length of time.

If a length is specified, and EXTRA_SKIP_UI is true , the implementation should remove this timer after it has been dismissed. If an identical, unused timer exists matching both parameters, an implementation may re-use it instead of creating a new one (in this case, the timer should not be removed after dismissal). This action always starts the timer.
