Hello ponraj

We need to know precisely when your App crashes - during the install? When a specific button is tapped? When swapping Screens?

What error messages do you see?

how we can check our program is correct or not because some time when we check in AI companion the program is working well but the same program when we install the app it is getting we can do final check before we share to somebody or install our app.


It would help us to help you if you read my earlier response and answered it!

What do use for Screen1 Icon?
That can kill an install if it’s too big.

any error message?
you might want to set Clock1.Enabled to false before opening any another screen

You must stop the sound of screen 1 when you switch to screen 2, or you must close screen 1 if you switch to screen 2.

To switch screens correctly, try this (on each of your screens):


This way, only 1 screen is open at a time.

Greetings, I had not seen that these instructions should be done when you have multiple screens. Thanks for sharing

Greetings, friend, can you share the application to see it and comment with more ideas? I am also a teacher

Hi, my group has a similar problem with our app in which it works fine when connected to the AI companion but crashes when it is installed. We cannot seem to find the problem as it does not seem to be an issue of memory storage or overlapping resource button.
Here are the codes:

Any help would be much appreciated.
