Another force close error

[Creampuff]

Hey everyone, I've just been trying to set up the AnalogOnscreenControlsExample in a standalone app and I can't figure out where a "stopped unexpectedly" error is coming from.

Both the andengine and multitouchextension libs are added to the build path, and the AndroidManifest has been edited to allow everything the example does...

Whats really throwing me off is I think the debugger is saying the error is in...
if(MultiTouch.isSupported(this))

As if it doesn't know what 'this' is... anyone know why this would be any different then in the example?

Thanks in advance for all the help!

SOLVED: I was apparently using an old version of the andengine.jar file. The systemsutil.class file was missing the hasSystemFeature method and this threw everything off.
