This Solves my problem. Well that happend to me as I tried to build my latest project. Solution was quite simple but… strange. Just remove all newer Android SDK build-tools (i.e. 19) until the Version 18.1.1 with the Android SDK Manager. Restart Eclipse. And it will work. If not, try to add the Support Libraries (Right click on your Android Project in Eclipse, choose Android Tools, Add Support Library)
