Android Question NullPointerException in zoomimageview

[angel_]

I have this error in Firebase that occurs (rarely) when starting the application:

page_app.Initialize
B4XPages.AddPageAndCreate("app_page", app_page)

Any idea why?

Fatal Exception: java.lang.NullPointerException

Is it possible that the initialization of app_page is not finished?
If so, add a Wait for App_Page_Ready.

And put CallSubDelayed(B4XPages.MainPage, "App_Page_Ready") at end of Initialize of the page.

Thank you for the response, it happens when Initialize or AddPageAndCreate the page during the startup of the app, I really can't get to that page, I don't have more information since I can't reproduce the error.

I appreciate that the code will be too large to post, and/or you can't share it.
Could you just post the initialize sub and B4Xpage_created sub?
Or PM those two subs (zipped if too large). I'll look at it. Perhaps fresh eyes will notice something.

I'm testing to see if I can reproduce the error since it doesn't always appear.
