Danny,

Android already keeps a global registry of pending intents, so keeping a parallel hash map should not be necessary.

To cancel an alarm, you don't need a reference to the original Java object, you can just construct a pending intent the same way as you did when setting the alarm (including the request code).

The hash table can go away with the process, while alarms persist (with them being inside Android). If you're relying on the map being an up-to-date representation of your alarms, make sure that it's correctly reconstructed from scratch - or get rid of it altogether.

Good Morning!

Wow, you helped me to get it work. I create a PendingIntent with a
unique id and store the intent mapped to their IDs in a HashMap. I
collect all intents with the known id and can the cancel them using
the AlarmManager. I dont know if it is recommended and efficient to
store those intents in a HashMap, but I need the PendingIntent when
I'll cancel the alarm and it worked.

Maybe I have to optimize something, but now I understood how to work
with the AlarmManager AND multiple scheduling tasks.

Thans a lot!

Danny,

The issue with multiple alarms comes up quite often, this is one of
several responses:

Hi,
the AlarmManager is exactly what I need. It works fine, but I don't
figured out yet how to set more than 1 alarm on a AlarmManager.
I am using a BroadcastReceiver to receive that is called if the
scheduling time is reached. First I forgot to add the receiver- Tag in
the AndroidManifest.xml and wondered why the alarm is not fired ^^ But
now it works, but only for the last data I set on the manager.
Hope you can help, meanwhile I go home and do some searches on
Google :D
´Thanks!

Hi,
I have a service that is running in background. It needs to send
notifications to the user. In my application you can create data with
date and time. The service now can fetch this data and give the user a
notification t-x minutes before the saved time is reached ("remind for
appointments").
Can I set a fix moment when the service should send the user a
notification instead of listen/check all the time for (approximately)
time identity?
See AlarmManager
And a secondary question: how can I set "Autostart" for the
applications service?
See Intent.ACTION_BOOT_COMPLETED

Thanks a lot!
