Android Question Strange (?) error with msgBox from firebase crash reports

[mc73]

I occasionally receive this:

Exception anywheresoftware.b4a.B4AUncaughtException:
anywheresoftware.b4a.Msgbox.msgbox (Msgbox.java:172)
anywheresoftware.b4a.keywords.Common.Msgbox2 (Common.java:443)

com.android.internal.os.ZygoteInit.main (ZygoteInit.java:768)

The line of code producing this error is a simple msgBox.
I found no way to reproduce this error to all my testing devices.
Is it something to do with not using asyncMsgBox?

use msgboxasync and wait for, had similar firebase crashes that i solved with this solution

Thank you, I will try that immediately However I would like to know the cause, just out of curiosity

try to lock the phone or minimize the app while the msgbox is visible and go back to the app after a minute or so, probably it will crash.

Excellent!

Avoid using Msgbox. Only MsgboxAsync.

This is the same issue as with using DoEvents.
