I have made an app. in which I use DatePicker, see attached blocks. This app works OK with Android 10.3.2 while it does prompt an error that clock should have format MM/dd/YYYY - see attached image:
well the problem was that blocks would not work on Android 6.0.1. It all worked well on OnePlus 6T (i.e. Android 10).
I did find out another “hickup”; namely Android 10 phone sends AM or PM information in local language, which in my case is “dop.” and “pop.”, while Android 6 refuses to send AM/PM in local language and keeps sending AM/PM no matter what I set on the phone. I did overcome that issue on the side of program that runs on my MCU.
