Android Question Chrono not working

[Rogerardo]

I have a program which has been live on multiple Samsung Galaxy tablets for many years. The program relies on the "Chrono" function for part of it's functionality.
Over the past weeks my customer had been updating tablets to Samsung Galaxy Tab A with Android version 9.
The Chrono function does not appear to work on these tablets.
Is there an alternative for the "Chrono" function or is there a workaround?
The program FTP's a few files from a Windows server and the Chrono stops the program continuing until the last of these files has been received but as Chrono does not work the program just hangs.

What is "the "Chrono" function"?

In what way does it not work?

Chrono is a timing function which allows the program to "wait" until something external happens. I use it with FTP. I issue multiple FTP's then a Chrono function keeps checking to see if the FTP's have finished. If not they delay the program for a second or 2 to see if the FTP's have completed yet.
I have an olded Galaxy tablet and a new one side by side, each doing the same task. The older one works fine. The newer one seems to just ignore the Chrono subroutine. I have around 200 older tablets which work. Around 30 newer ones (All Samsung Tab A) which fail. It is as if the Chrono subroutine is completely ignored.

That doesn't tell me what the Chrono function is. It is not a B4A keyword so what is it? Is it a library object? If so what library is it in?

Post some code showing how you use it.

Have you try It with wait for?

Android version 9

As this is a new device and i know you should use a recent B4A Version to get apps working on newer Devices

What B4A Version are you using?

 

[Rogerardo]

I am using version 7.01

I am using version 7.01

I guess you need to have at least B4A 8+ to get the app on Android 9 working correctly.
There are some changes which you need to take care of.

Check this thread:

I suggest to update to B4A 9.3

I have upgrdaded to the latest version. Chrono still does not work.
Fine on emulator. Fine on older tablets. Fails on newer tablets.
I am trying to program around it.
