Android Question Custom toast message error

I'm not familiar with this implementation however generally speaking it is a mistake to set the width to -1 or -2 in B4A.

You can use Canvas.MeasureStringWidth to find the right size.

It worked fine on Android 4.1 and the problem sometime appears on Android 5.1.1.
