Question

My app will have several alarms set simultaneously. Unfortunately, each alarm is being set with the same PendingIntent object. Here’s the code I’m using to set the alarm:

//Use AlarmManager to trigger the notification/alarm.
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

//PendingIntent to launch activity when the alarm triggers.                    
Intent i = new Intent("com.testapp.DisplayNotification");

//Assign the reminder's primary key as the notification ID.
i.putExtra("Reminder_Name", editRemindMeTo.getText().toString());
i.putExtra("Reminder_Primary_Key", reminderPrimaryKey);

PendingIntent displayIntent = PendingIntent.getActivity(
getBaseContext(), 0, i, 0);               

//Set the alarm to trigger.
alarmManager.set(AlarmManager.RTC_WAKEUP, 
c.getTimeInMillis(), displayIntent);

I know that I can delete an alarm by using the following code:

AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); 

Intent i = new Intent(context, MyPendingIntentService.class);
PendingIntent displayIntent = PendingIntent.getService(context, 0, i, 0);

alarmManager.cancel(displyIntent);

However, using this code will delete ALL my alarms (correct me if I’m wrong here). Is there a way to delete just the alarm that a user has deleted from the database? The alarm should be deleted from my app right after the user deletes an alarm entry in my app’s database. I’m guessing that using different PendingIntent names would be the way to go, but I have no idea how to do this for each new alarm that a user creates. Thoughts on how to do this? Thanks!

See the same problem i faced here previously…
So the solution is to pass unique pending intent to the alarm service.. So here i how it can be done

PendingIntent pIntent = PendingIntent.getBroadcast(context, (int) alarm_id, intent, PendingIntent.FLAG_CANCEL_CURRENT);

here in the pending intent i have passed unique request id to the pending intent. Which you have to remember while cancelling the alarm.
So in my case what i have done to generate the unique id is put it in the database i have retrieved the id of the tables row and passed to the pending Intent.
So if you want to cancel the particular alarm you have to remember the same request id of the pending intent with the use of the same table entry…

I am sure it will work..
