Unable to make a build?

Hi,

I am unable to make a build for android, its saying

Error building Player: UnityException: No platforms found
Android SDK does not include any platforms! Did you run Android SDK setup to install the platform(s)?
Minimum platform required for build is Android 4.0 (API level 14)

Now I have android 8, 10, 14 & 17 installed but its still saying the same thing… plss help its urgent…

Got it…it seems like there has been some changes in the Android SDK tools revision 22 which unity is yet to incorporate. Seems like rolling back to revision 21 fixes the problem
