I had the same problem, but after several hours and many other problems i solved it. I assume you are using also Eclipse, otherwise the solution will be different.

You have to update your android in the SDK manager. Especially the Android SDK Build-Tools and afterwards you have to install API20. Now you have to update your ADT as described here: https://stackoverflow.com/a/24437737/2061089 Don't worry after the update its working now. Before you can install the update, you have to remove all components that you want to update.

After restarting eclipse you only have to update ALL your support(v4,v7 and v13) packages in your projects. Depending on what you are using.

Finished. Now everything is up to date and eveything is working.

Hope it helps!
