Hello everyone, I'm having a bit of an annoying problem. Having followed the instructions listed under the Hello, Android! example, I have found that the compiler refuses to run the code (which I copy- pasted directly from the example text boxes to avoid errors.

I downloaded the plugin, but it continues to manifest three errors:

Severity and Description Path Resource Location Creation Time Id Error executing aapt. Please check aapt is present at \tools\aapt.exe Helloandroid Unknown 1199760483578 24 Project 'Helloandroid' is missing required library: '\android.jar' Helloandroid Build path 1199760117796 15 The project cannot be built until build path errors are resolved Helloandroid Unknown 1199760483578 25

These are a touch arcane, so could anyone tell me what precisely they indicate?

Have I missed something obvious?
