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. Android TV devices may not support the alarm intents. /**

public final class AlarmClock {
    
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.
 This activity could also be started in Voice Interaction mode. The activity should check Activity.isVoiceInteraction, and if true, the implementation should report a deeplink of the created/enabled alarm using CompleteVoiceRequest. This allows follow-on voice actions such as ACTION_DISMISS_ALARM to dismiss the alarm that was just enabled. 
Request parameters

EXTRA_HOUR (optional): The hour of the alarm being set.
EXTRA_MINUTES (optional): The minutes of the alarm being set.
EXTRA_DAYS (optional): Weekdays for repeating alarm.
EXTRA_MESSAGE (optional): A custom message for the alarm.
EXTRA_RINGTONE (optional): A ringtone to play with this alarm.
EXTRA_VIBRATE (optional): Whether or not to activate the device
vibrator for this alarm.
EXTRA_SKIP_UI (optional): Whether or not to display an activity for
setting this alarm.

Activity Action: Dismiss an alarm.

The alarm to dismiss can be specified or searched for in one of the following ways:

The Intent's data URI, which represents a deeplink to the alarm.
The extra EXTRA_ALARM_SEARCH_MODE to determine how to search for the alarm. 

If neither of the above are given then:

If exactly one active alarm exists, it is dismissed.
If more than one active alarm exists, the user is prompted to choose the alarm to
dismiss.

 If the extra EXTRA_ALARM_SEARCH_MODE is used, and the search results contain two or more matching alarms, then the implementation should show an UI with the results and allow the user to select the alarm to dismiss. If the implementation supports Intent.CATEGORY_VOICE and the activity is started in Voice Interaction mode (i.e. check Activity.isVoiceInteraction), then the implementation should additionally use PickOptionRequest to start a voice interaction follow-on flow to help the user disambiguate the alarm by voice. 

If the specified alarm is a single occurrence alarm, then dismissing it effectively disables
the alarm; it will never ring again unless explicitly re-enabled.

If the specified alarm is a repeating alarm, then dismissing it only prevents the upcoming
instance from ringing. The alarm remains enabled so that it will still ring on the date and
time of the next instance (i.e. the instance after the upcoming one).

Activity Action: Snooze a currently ringing alarm.
 Snoozes the currently ringing alarm. The extra EXTRA_ALARM_SNOOZE_DURATION can be optionally set to specify the snooze duration; if unset, the implementation should use a reasonable default, for example 10 minutes. The alarm should ring again after the snooze duration.

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.
