Notifier (.ShowChooseDialog) / bug after switching screen

[bodymindpower (Anke)]

The Notifier (.ShowChooseDialog) only works after the first initialization (Screen1.Initialize). If I switch to Screen2 and then back to Screen1, the Notifier no longer works. (You must reload Screen1)

How to switch screens correctly

I see many issues done by users because they switched screens not correct. This below is now just one of many other solutions: [blocks] If you dont open/close screens correct your app will get possible runtime errors. Possible errors: (example) Unable to add window -- token android.os.BinderProxy@45d459c0 is not valid; is your activity running? Iam sure you don’t want that. Then please do it in the future and switch screens correct. General Tips and Tricks for App Inventor/Makeroid …

It’s not a bug

to what extent no bug?

[Boban (Boban Stojmenovic)]

In Kodular it is not classified as a bug, they made it work like this

Notifier is not displayed after the screen change

Solution for all people that get the same issue Please open and close screens correct @ all https://puravidaapps.com/tribblehunter.php

Yes, it’s a big bug​

[AvTaar]

Please open and close screens correct @ all

In some apps, for some reason, we can’t close all screens

[bodymindpower (Anke)]

it’s a big bug

Yes, and I need it in every one of my apps.
Why doesn’t it work with Kodular in particular? With all other AI distributions there are no problems.
Reloading the screens can be time-consuming and annoying on older devices.

Btw, there are no problems with .ShowAlert (instead of .ShowChooseDialog).

in starting i also face that and tried to hard to get rid of it until i have seen how to switch screen correctly, after closing other screen, this will not work, so close you screen before opening other screen.

I have this same problem too. And I just needed to close the screen open and keep the main one without reloading. But it seems that this only happens when there is the “Notifier” component on the new open screen. If not, it works normally.

I got your point … and tested your app …
But still a problem with that …

Because my app have a screen with a notifier and this screen has a listview
…
When choosing from the list view … it changes the data of the list to a sublist and the slection from the sublist opens a nother screen

I need when the second screen closed to be back again on the sublist …with a working notifier …

Could you help?

[janieltoncnn (Janielton Santos)]

Are you using the notifier component on the second screen?

[drpeterramsis2007 (Peter Salib)]

Yes … notifier is verg necessary

[janieltoncnn (Janielton Santos)]

Well, in my project I had to adapt the other page to not need the notifier and I removed it. That was the only way I found, other than that I don’t know how to make it work.

Maybe I catched (finally) today the bug.
It was a static variable to the activity.

Hopefully this bug will be gone in next release
