Question

I am setting up AlarmManager with a PendingIntent in activity A.
Then I would like to be able to call cancel() on the same PendingIntent from a different activity B.

The Android documentation says the following:

“If the creating application later re-retrieves the same kind of PendingIntent (same operation, same Intent action, data, categories, and components, and same flags), it will receive a PendingIntent representing the same token if that is still valid, and can thus call cancel() to remove it.”

Is it possible to store a PendingIntent in a database
and retrieve it from a different activity?

Answer 1

If you are not creating your PendingIntent in a dynamic way, then you just need to create it the same way.

I would recommend creating a singleton that will create and deliver your PendingIntent. That way, you could call something like this from anywhere in your application:

PendingIntent pi = PendingIntentHelper.getInstance().buildPendingIntent();
am.cancel(pi);
