Graphical Layout Raise Problem

yesterday i have update my avd at that time internet connection are disconnect.and i got a problem in Build & run project.so simple i have Clean it. and its goes to working fine but when i open any xml file it will give message like "LayoutLib is too recent. Update your tool!" i think that any tools are missing it will update shortly.but not getting any update. and in any project while i have open project it will give message again this.

i have attach one screen short please consider it and tell me what is the problem?

Note: this is not a xml file problem开发者_开发百科 it is globally eclips or plugins problem

update your SDK in eclipse, by going to Window>preferences >Available packages select the latest package and download

EDITED

In the "Graphical Layout" tab of the layout editor there is a dropdown(above theme) for selecting the Android version to use. so select a compatible version and you're probably good to go.
