Android: Manage variable value with alarm manager event?

Question

In my code, I have an AlarmManager and it triggers a notification when the time elapses, which works fine. When setting the alarm, the alarm details are saved into DB, when the alarm is set off, I need to recall the alarm information, is there some form of variable I can save into the DB.

Answer 1

The key you were looking for is PendingIntent.

long dbid = db.insert("<query>"); // or any other db transaction

Now create normal intent for AlarmManager.

Intent intent = new Intent(this, AlarmEventReceiver.class);
alarmIntent.putExtra("dbId", dbid); 

Then add to Pending Intent.

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0,  intent, 0);

In onReceive method on AlarmEventReceiver

long dbid = intent.getLongExtra("dbId", 0);

Note: AlarmEventReceiver is subclass of BroadcastReceiver
