I can't find in android documentation about alarm or something like that. I mean I found class NotificationManager but it doesn't work satisfactfully, for exmaple: when i use function notificationManager.cancel(id) then icon dissapear form status bar, vibration stops but a sound still play in the background. I use FLAG_INSISTENT (te best for alarm for me). I use this alarm for wake up and i want write snooze function too, so I don't know that NotificationManager is useful for this.
thank you in advance
