No available targets

I apologize in advance for an extreme newbie question.

To start off android development, I tried to create a 'Hello World' application as documented on developer.android.com. The first step in that is creating an avd (android virtual device)... and to create an avd, we need to specify a target. The problem is my system seems to have no available targets. When I try to run this command:

tool>android list targets

I get blank Available Android targets

Not sure what I did wrong in installation.

Any help would be appreciated!

Hi,
I think you need to create a virtual device first.

Kudret,
Thanks for your reply. Actually I was not being able to create virtual device since I didn't have a "target".

I was able to solve my problem. by uninstalling the ADT and Android SDK & then reinstalling SDK as per the directions on android site.
