Okay, can you copy and paste them in here? We might be able to help you troubleshoot.

yes I will do that, can I posted here in about an hour ?

Sure! I'll try to keep an eye on it, but I might not be able to get back to you right away. Of course, other students can always chime in, too. :)

Sorry to have missed this before the weekend. I'm not sure at all what the problem might be. Your best bet might be to start from scratch using the Android bundle from the Android Developer site: http://developer.android.com/sdk

This is pretty much the same thing as the Treehouse bundle. At this point the only difference is that we create a default emulator for you. We show how to do that in the videos, though, so this will hopefully get you going again.

You could try our Treehouse bundle, which you can find in the Teacher Notes of this video: http://teamtreehouse.com/library/build-a-simple-android-app/getting-started-with-android/android-setup-and-the-crystal-ball-project-2
