In my app must the hundredths of seconds to be displayed without a stumble.
It is also important that the beep is output precisely to the hundredth of a second.
I do not need background thread but a multi-threaded or parallel thread.
At best, the same as the threading library of B4a.
Probably when I create a small project, then the timer does not have any problems. My project is very big and bulky and then it makes no sense. I had also tried using Android in the beginning with a timer and had exactly the same problems. Only with the threading library I could fix the problem.
