So, browsing on the Web I found that this problem maybe caused for use ADT 22 or above but in my case I'm using the 21.0.1 version, I would like to ask:The chosen folder is not a valid Android SDK Please ensure you have installed it correctly, and enabled support for Android 2.2 Froyo
1. do I have to look for a specific directory inside the SDK?
2. what am I missing? in fact I know ADT is working because I can code using Eclipse+ADT
3. do you any suggestions?
cheers
