The blocks (image at the beginning of discussion) show the whole project.
Actually i was having problem in other project . That crashes again and again when it has to some message. So i created a new simple project to test notifier in order to confirm the problem.

Please show a picture of your notifier designer properties.

The error log tells me that you have no background color set.

properties_notifier

everything is in default

#13

What is if you set the background color to a other color?

#14

Still crashing :frowning:

EDIT:
@ All
Please test the apk, write your android version and if you see or don’t see the toast message.
Thanks

I can’t rebuild your error.
I have created a new project.
All I have done is added a button and the notifier component.
I have nothing changed on the notifier properties.

My blocks:
blocks (4)

Here is the apk:
toast.apk (2,3 MB)

The apk works for me and shows the toast without issue:

I dont know why it is not working for me.
But finally i have fixed it through other way.
I decompiled the apk file using apk tool .
Went to
Smali > com> google>appinventor>component>runtime

Replace the notifier.smalli file with another same project created on mit app inventor.

It is old not like toast but working without crash.

Which android version had your device before you install the custom Rom?
Maybe the custom rom is the issue creator.

Because i can not rebuild your issue.
