Specifies whether user interface should be skipped. Default is true.
Event raised after setting the alarm.
Note: you have to build the app to be able to use this method!
Q1: I find it a bit strange that your error messages say something like "hour should be < 24" while you just test for the text field being empty.
A: Yes, you are correct. The better solution is to check for empty string and additionally for hour < 24 and minute < 60.
Developing and maintaining snippets, tutorials and extensions for App Inventor takes a lot of time.
