Adobe AIR native extension

Access to application options and device information

The extension is available here: com.distriqt.Application


The Alarm Manager functionality allows you to use the Android Alarm manager to set your application to receive events at a particular time. It also allows you to launch your application into the foreground if you require.

Android: Manifest Additions

There are some manifest additions required for this functionality, add the following to your manifest. There are two receivers and an activity required. The first receiver is required to restore alarms after a reboot and the second to actually receive the alarms.

<manifest android:installLocation="auto">
	<uses-permission android:name="android.permission.INTERNET"/>
	<uses-permission android:name="android.permission.READ_PHONE_STATE"/> 
	<uses-permission android:name="android.permission.WAKE_LOCK" />
	<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
		<receiver android:enabled="true" android:name="com.distriqt.extension.application.receivers.ApplicationStartupReceiver" android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
				<action android:name="android.intent.action.BOOT_COMPLETED" />
				<category android:name="android.intent.category.DEFAULT" />
		<receiver android:name="com.distriqt.extension.application.alarms.AlarmReceiver" android:enabled="true" />
		<activity android:name="com.distriqt.extension.application.alarms.AlarmActivity" />

Checking Availability

You should check whether the alarm manager functionality is available on the current device before attempting to use any of the functions below.

if (Application.service.alarmManager.isSupported) 
	// AlarmManager functionality is available

The Alarm Manager will not be available on some platforms eg iOS does not currently support this functionality.

Register for Events

Next you will need to do is add an event listener for the alarm events and register for the events. The AlarmEvent.ALARM is dispatched whenever an alarm occurs.

Calling register() will not only register for alarms but also check if the application was launched from an alarm, so an alarm event may be dispatched immediately after a call to this function.

Application.service.alarmManager.addEventListener( AlarmEvent.ALARM, alarmHandler );


private function alarmHandler( event:AlarmEvent ):void
	trace( "alarmHandler: [" "] " );

Creating an Alarm

To create an Alarm you use the setAlarm function of the AlarmManager and an AlarmBuilder.

The AlarmBuilder is a helper class giving you the easy ability to setup an alarm correctly.

You can pass a String as the data of the alarm that will be returned in the alarm event. This can be used to distinguish which alarm occurred in your application. We suggest using an stringified JSON Object as below.

var data:Object = {}; = Math.floor(100*Math.random());
data.message = "a distriqt alarm";

var timestamp:Number = new Date().time + 10000 ;

	new AlarmBuilder()
		.setId( )
		.setTime( timestamp )
		.setData( JSON.stringify( data ))

Cancelling an Alarm

Cancel by ID

The simplest way to cancel an alarm is to cancel the alarm by the ID of the alarm:

Application.service.alarmManager.cancelAlarmById( id );

This id should be the same as the id passed to your AlarmBuilder.setId( ) call.

Cancel by Alarm

You can also cancel an alarm using the Alarm object that you previously built and passing that to the cancelAlarm function.

Application.service.alarmManager.cancelAlarm( alarm );

This alarm object can either be stored from the setAlarm call or reconstructed using an AlarmBuilder with exactly the same parameters as used previously. For example matching the call above:

	new AlarmBuilder()
		.setId( )
		.setTime( timestamp )
		.setData( JSON.stringify( data ))

Cancel All Alarms

To cancel all previously set alarms, simply call the cancelAllAlarms function.
