问题 I've read some of the other posts on this subject and I think my code should be sounding an alarm, but it's not. It does vibrate, but no sound. Any suggestions on how to get this to convey sound ? Another part of the program is able to play a ringtone so the problem seems to be specific this routine. This is in a class that extends Service @Override public int onStartCommand(Intent intent, int flags, int startId) { Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

问题 Is there any way in Android to detect when a user swipes a notification to the left and deletes it? I'm using an alarmmanager to set a repeating alert and I need my repeating alert to stop when the notification is cancelled by the user.

问题 I'm trying to create a reminder application that pops up a reminder in the status bar. As I understand, the Android NotificationManager is the standard tool to use to schedule notifications however a BootService is needed in order to re-schedule notifications as scheduled events do not survive across boots.
