Eclipse doesn't open Android XML Library files.

Recently I ran into an issue that Eclipse didn't want to open XML files that are located in android.jar/res.layout directory. The reason is that android uses Android Common XML Editor. The only thing to do to open binary xml files is to change default XML Editor to Android Binary XML Editor. To do so go to Window -> Preferences -> General -> Editors -> File Associations and change default XML Editor to Android Binary XML Editor.

Could not open the editor.
