Hi I am developing an application like alarm clock that will allows the user to set a time and sound url. And when the time runs out the application should start automatically by playing the sound url. How this can be possible in Blackberry 10.Any one know the answer please help me.
The current way to approach this is by using a long-running headless application.
Check here for more info on headless apps.
Your long-running headless application would run in the background and process any alarms the user sets. You could store the alarms in QSettings.
In the upcoming OS 10.3 Gold SDK, you'll be able to use a short-running headless app with a timer trigger.
