@Taifun I just started testing ...
First problem: on an Android 5 device I get an error (End Application):
This date format works: MM/dd/yyyy
But even when I changed that, I get a Runtime Error, after clicking on Start.

I unlist this thread meanwhile we are doing some more tests...
@Anke please first test using the newer devices, i.e. Android 11, 10, 9 and 8
also from your feedback I can't see, what exactly you are testing... it seems to be, yo are testing the FormatDate block?
if you like to start an alarm only once, you have to pass an instant as input parameter for the datetime

I tested the alarmmanager2.apk on some of my test devices.
It works on:
- Pixel 2XL (Android 11) → works
- Galaxy Note8 (Android 9) → works
- Xiaomi Redmi Note 5 (Android 9) → works
- Nexus 5x (Android 8.1) → works
- Galaxy A3 (2017) (Android 8.0) → works
- Galaxy S6 (Android 7) → works
- Galaxy Note 3 (Android 5) → works
Does not work on:
-
Xiaomi Redmi Note 5 (Android 9) → doesn't work (also not in foreground)
(EDIT: Notifications were disabled, no idea why) -
Galaxy S6 (Android 7) → doesn't work (also not in foreground)
(EDIT: new test APK works now) -
Galaxy Note 3 (Android 5) → crash (as already reported → date format)
(EDIT: new test APK works now)

I tested it on my Pixel 4a (Android 11) and your alarmmanager is working and showing the notification.

That error with date format YYYY vs yyyy looks to be a can of worms, from what I see about week years in
https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
and
Beware of Java version changes for week year formatting.

So just format it like this: → MM/dd/yyyy, then there shouldn't be any problems with any Android version.

I'll buy it if it runs in the background
without that it would be useless...

I tried the version 4 of the alarm with the "alarm manager example app", but it did not send notification until I fully closed the app. I tried on different devices and made sure the Android version is up to 5, but it still did not work.
@Nelly Add this block and try again.
Do you see the "ALARM !!!" notifier, if the app is in the foreground or in background (but not closed)?
Note: You also get the message "Welcome back, you are amazing" at the bottom of the screen.
Thank you for your reply!
I've tried this, but sadly it still did not work 
Really Thanks a lot for your help!
I downloaded the app and tried a few time, but it still send the notification only when the app is fully closed.
My device type is HTC One A9s, and my android version is 6.
The question was:
Try this:
Put the app in the background by clicking on the device Home button and wait ...
The app will be opened at the picked alarm time:
