Android Question Firebase Exception: Can't start async operation (refresh inventory) because ...

[Deleted member 103]

Hi,

I have a Firebase Exception here, I can not find a bug in my code.

Can't start async operation (refresh inventory) because another async operation(refresh inventory) is in progress.

Which should be the second "async operation"?

Firebase Exception:

Fatal Exception: java.lang.IllegalStateException: Can't start async operation (refresh inventory) because another async operation(refresh inventory) is in progress.

You are setting the Cancelable parameter in the call to ProgressDialogShow2 to true. This means that the user can cancel the dialog and quickly click on the button again. This will cause two requests to be sent.

WOW! How easy is the solution?
Thanks Erel
