Ahh gezz Sad

I've already done the catch. I know what function it occurs in. Its using variables declared outside of the function. Should I declare those public?

Hello!

This might be the wrong forum, but I couldn't find a different place to post it. My problem is is that I'm getting a java.lang.NullPointerException when ever I try to draw on a canvas. Can anyone tell me why I'm getting this?

Thanks,
