I'd been using this tutorial: http://www.adobe.com/devnet/html5/articles/getting-started-with-phonegap-in-eclipse-for-android.edu.html
To try to make the "hello world" program with PhoneGap but couldn't get it to launch on the emulator. I gave up and used the example project that came with the PhoneGap download, and I can't get it to load on the emulator either. I've messed around with the emulator for like an hour and nothing seems to work.
I used this to install the SDK: http://developer.android.com/sdk/index.html
Also I'm not getting any errors.
