I am using android-sdk-macosx to download from the internet, then installed Android SDK 2.2 and 2.1 successfully, then I tried to create new AVD on mac, but I don't have any idea about how to create AVD.
I tried this below mentioned for your reference:

Fig 2.0 I tried to open SDK and AVD Manager in eclipse menu Window --> Android SDK Manager
