I had that one and for me it was a problem with the 'R12', it doesn't accept spaces in the install directory (of the Android SDK).

Instead of uninstall/reinstall, I changed in Eclipse from c:/program files/... to c:/Program~/... and it worked.

I didn't invent it, I found it here : Starting the Android emulator in SDK tools, revision 12

SDK Path can't contain any spaces

Make sure your sdk path contains no spaces.May be you are changing the path of the android sdk folder.The path can't contain spaces.Like if you keep it in Program Files/android-sdk-windows it will create problem because Program Files has a space on the path
