Apps Problems keeping App up-to-date

[Cheekymonkey]

Hey guys,

i'm totally new to app development, so please be kind with me.

I'm following a tutorial series on YouTube to create a little 2d GameApp. Everything worked out so far, but I got to a point, where I got an NullPointerException while creating a Bitmap.
That was correct, because I didnt give one reference a value. That's how the guy from the tutorial fixed this issue.
Sadly, it didn't work out for me and I can't figure out what's wrong, since i nearly copied everything from this tutorial.

One thing led me suspicious. The stacktrace always say "line 31", even I deleted this line and skipped it, so I think, Android studio might not update the App (running with physical device) properly.
Can you guys give me any advice?

Thanks a lot
