While my application is in Active Frame mode I have an alarm that fires based on a users setting. The user gets to set the interval on how often the cover frame screen updates. 

While debugging my aplication using the DEV Alpha I noticed the Alarm keeps on firing even when the screen shuts off. In order to help reduce battery drain I would like the Cover alarm to stop firing when the screen turns off and start again when the screen is back on. Is this possible?

The alarm i set is : QNXSystem.system.setAlarm(1000*alarmTime, True);

Cancel the alarm with cancelAlarm()...

Yea but what event indicates that the screen turned off and turned back on?

[apman · Accepted solution]

IowWindowEvent.WINDOW_STATE_CHANGED  lets you monitor exactly whether your app is only minimized or completely hidden, so you can cancel the system events while they are not needed (IowWindowState.THUMBNAIL, IowWindowState.HIDDEN and IowWindowState.NORMAL

My app : Get set - Get up!   Get ready for the snooze revolution.

The very same page that documents setAlarm() and cancelAlarm() describes active, inactive and standby events...

Thanks that did the trick!! 

Also, found the documentation all here.. 

https://developer.blackberry.com/air/documentation/bb10/respond_change_application_state.html

It also notifies me when the application can't be seen.
