Android Question Just starting. Error on line... I don't have that many

[Nimbus4]

Screenshot attached. I'm just starting out, and am making a simple app. I keep getting error on line 72? I don't have a line 72. It doesn't cause the app to crash, but... I'm confused. I hate being confused. It's so confusing being confused.

Now I'm even more confused. I changed nothing and it went away. All I did was take a screenshot, write this post, then go back and rerun the code, and it's gone.

This Error is happening, when you initialize a Canvas on a View that has a width or height < 0. For example when you have height -1 to Fill the parent.

But I dont see why the Error is gone. Maybe try to log the size of the canvas view and try to prevent this Error from happening again.

Not using a canvas. Have never used a canvas in this app.

why not just use Activity.Width/Activity.Height instead of GetDeviceLayoutValues?

Because I'm still learning . But that's a good idea. I will do that. Thanks.

You should run your code in debug mode. It will show the correct B4A line. You are seeing the Java line number.
