Check
whether Recyclerview is existing in the SDK or not because it is a
part
of the support library.

you're not find the folder “recyclerview-v7” in the following sdk directory "..\sdk\extras\android\m2repository\com\android\support" then follow
the steps otherwise follow from step 3.
Steps
to achieve:

- After updating Android Support Repository from SDK Manager go to..\sdk\extras\android\m2repository\com\android\support\recyclerview-v7\21.0.0-rc1
- Unzip recyclerview-v7-21.0.0-rc1.aar
- After unzipping recyclerview-v7-21.0.0-rc1.aar you will get classes.jar
