No android sdk found error

Hi,

I am trying to configure android sdk into titanium studiod, but i m getting this error everytime.

[Android SDK Home] No Android SDKs were found under the specified SDK location

I m using mac OS - 10.8.5, titanium sdk - 3.3.0.

I tried setting the path from preferences -> Platforms -> Android -> Android SDK Home. I even downloaded the SDK from developer.android.com, even for that folder i m getting the same error. When i try to install new sdk like 4.4.2 or something, it flows smoothly without an error but it doesn't reflects in the folder.

Can anyone plz guide me through this.
