我创建Android项目，但是随后我立即获取信息已经出现了错误。

I created Android Project but then I immediately get information that there have been errors.

Warning:(22, 12) Dependency on a support library, but the SDK installation does not have the "Extras > Android Support Repository" installed. Open the SDK manager and install it.
