Android Question NumberFormat Exception but there is no number involved?

[Didier9]

This line of code:

Dim i as Int
i = Msgbox2Async( "Do you want to save your changes?", Starter.AppName, "", "Save As", "Do Not Save", Null, False )

causes that:

Error occurred on line: 492 (Script)

Line 492 is the MsgBox2Async() line

This is the app running on a hardened Samsung tablet. It is apparently not fully running...

As usual, any help appreciated.

The proper way to call Msgbox2Async is shown in the contextual help:

Dim sf As Object = xui.Msgbox2Async("Delete file?", "Title", "Yes", "Cancel", "No", Null)
Wait For (sf) Msgbox_Result (Result As Int)
If Result = xui.DialogResponse_Positive Then
    Log("Deleted!!!")
End If

You should also note that to hide the Negative button you should pass an empty string. An empty string is "".
If you do not want an icon you pass Null for the icon

Thank you, I did see that my Msgbox2Async syntax was not correct, but the example I found was also incorrect, yet was not causing a compilation error, just th code did not do anything and I was in the process of pulling whatever hair I have left...
It is now working, thank you!

PS: I need to use the Contextal box more

This at least has not changed, and I was already taking advantage of that.
Thank you!

That "Copy" is awesome!
It would be nice if it was in all contextual help.

Line 492 is the MsgBox2Async() line

As you writed, the issue is not on compiler but in running time, so I think that line 492 is not refered to your source code but on java source.
You are seeing MsgBox2Async() line, but IMHO it is not the issue line
