Answer 1

I had the same problem. When I ran the SDK Manager, as FeatheredOrican suggested, it indicated that the support library was installed but it was out of date. Updating it fixed the issue.

Answer 2

You have to add the support library to your project

1.Download support library from SDK Manager

2.Right click project in eclipse -> add support library

Compatibility issues may occur I recommend Updating to Keplar
