Apps App fails to compile

[KarneeKarnay]

I am very new to development on Android phones and started to use AndEngine today. Ran into a weird bug when I was following a basic tutorial. Whenever I run this tutorial example on my tablet it says that the app just fails to work. As far as I can tell the problem is that it doesn't even compile. Any ideas?

Error output below:
