Android Question need assistance with firebase report

[tsteward]

Gday all smarter than me
My app crashes for some users but not all. I don't understand why.
I have installed firebase Crashlytics to try and figure this out. One problem it reports is height and width must be > 0
I have attached the stack trace. Is anyone able to explain to me how to determine from this what the error is and where?
I believe its in b4xmainpage

Help please

You are calling B4XCanvas.Initialize with a zero sized panel.
It happens in B4XMainPage.B4XPage_Create.
