layoutlib.jar is missing! : Plug-in "com.android.ide.eclipse.adt"

Question

I am getting an error in graphical layout of xml after installing the updates from :

• SDK Manager

• help->check for updates

Tell me how to get rid away from this problem ?

Thanks

Solution

Changing the api level(at top right of graphical layout) from 19 to 18 fixed this problem ! :)
