If you go to your project's properties dialog in Eclipse and click on the Android section, which SDK is checked? — Tony Allevato, Nov 21 '13 at 14:47
can you give us a screenshot ? What IDE? Eclipse? What other projects do you have open in that workspace ? — fabrizioM, Nov 21 '13 at 20:37

You have to set your project to compile with the Glass GDK.

Make sure you're targeting 15, have the GDK downloaded as per the other answer, and then:

Select your project on the left side of the screen, open project poperties (alt-enter, or right click -> properties), go to Android tab, scroll down to Android 4.0.3, and in that section will be the Glass Development Kit Sneak Peak. Check the box next to this, hit ok and everything should start working.

EDIT:

Just to make sure, your manifest should have this line:

    <uses-sdk
    android:minSdkVersion="15"
    android:targetSdkVersion="15" />

Make sure you are targeting API 15 and that you installed the glass development Kit. See the Picture:
