Android-Hello World

I'm currently learning how to create android applications so I started with the basic "Hello World" tutorial over at the Android Developers home page. The code is quite simple but when I run it(I'm using Eclipse and a AVD v2.2), it only shows "Android." It does not go to the Home Screen. I updated everything and I still get the same problem. Is there something I did not or

New errors:

I restarted my virtual device with the option Wipe User Data checked and then reran my app. That finally worked for me.

Note that in response to the other comments, I also tried the following:

  • Simply restarting the device
  • Restarting the device after changing the VM heap size
  • Restarting my computer
