You need to update your Android Build Tools to a later version. Unfortunately like a lot of things in the Android SDK it's not obvious how exactly you do this.

• Open the Android SDK Manager
• Under Tools, tick "Android SDK Build Tools 20" (or whatever the newest version is
• Click Install Packages
• Restart Eclipse
