Android Question Wait For

[Dey]

Hello to all
I have a class with a timer that keeps a table from a server
This class is initialized in an activity 1
Step to other activities eg. 2 3 without making 1.Finish
Occasionally happens that the pass or return to activity 1 generates this error
I think due because activity 1 is paused or pauses
How can I fix it?
I also put a Try Catch but it is not intercepted
Unfortunately and random I can not replicate it ...
Thank you

                CallSubDelayed2(Me,"TavoloRichiestaSingolo_result",st)

What is the signature of this sub (first line)?

This is the sub
This is the sub
The problem may come from the statement
Dim st As ts_tav
And Wait For Returns the same variable name?
Thanks Erel

Dim st As ts_tav
And Wait For Returns the same variable name?

It shouldn't matter.

Are you sure that there is no sub named TavoloRichiestaSingolo_result? Or another place where you wait for this event?
