Importing google client dependencies

Please follow the third apprach in my link, since your library is available online (remotely) as you see in the picture below. Android studio will recognize your dependencies if you add them in their standard ways. In general, there are three standard ways. Please read this linkhttp://stackoverflow.com/a/35369267/5475941. In this post I explained how to import your JAR files in Android studio and I explained all possible ways step by step with screenshots. I hope it helps.

Also, check your build.gradle (Moducle: app) and make sure your remote libraries are compatible with your current SDK. For example my SDK is 23.1.0:
