Android Question B4X question about heavy sub in the background

Erel said:

First step is to measure the actual time that it takes the heavy sub to complete. Make sure to test it in release mode.

No need to move the Sub.

I assume they are calculations inside For-Next (or Do While/Until) loops. Put a Sleep(30) inside one or more of them (30 is an approximate value).
Note that the Sub containing Sleep becomes a Resumable Sub, so treat it as such, in the way you execute it (using Wait For) and for the data type it returns.



The "progress bar" as you described it is not a progress bar, but something that rotates until the processing is complete. You can find some like that on the site.

Its something like this you describe. However, i feel that adding sleeps in between steps would increase the waiting time unnecessarily, wouldnt it?

Yes but it is necessary, otherwise no animation.
The alternative would be to use threads.

That's true. You need to call Sleep(0) inside your code. Don't call it every loop.

Do something like:

If index Mod 100000 = 0 Then Sleep(0)
