My problem was the same. I've tried to add SDK components using Eclipse. However, after the process seemed complete, directory C: \android-sdk-windows\platforms was empty! I've noticed that after unsuccessfully trying to execute "android list targets" command mentioned in your question.
Earlier on, I've added to the PATH environment variable the text: C:\android-sdk-windows\tools Following the advice found in the Internet, I've added to the PATH variable also this: C:\android-sdk-windows After that, I've restarted Eclipse and added SDK components once again (using Window >Android SDK and AVD Manager). Unfortunately, my HDD had no more free space, so I had to fix that. At last, SDKs' download and installation succeeded. Now C:\android-sdk-windows\platforms contains folders "android-1.1" etc., and the command android list targets works. -- You received this message because you are subscribed to the Google Groups "Android Beginners" group.
