I want to test against Android 1.3 platform instead of latest 2.2.
Here is how my Android SDK and AVD Manager look likes.

However, I was expecting (screen from http://developer.android.com/sdk/installing.html#components), so that I can select old platform.

Is there anything I had missed out?
Run Help > Check for Updates first, to update your Eclipse plug-in, then you can access the repository. Why would you want to test against 1.3? If anything is still on that old a version of Android (was there even a 1.3? It’s not listed here), it’s an insignificant portion of the market. The earliest you should even worry about is 1.5.
