title: Failed to build Android project with Google Play services
body: <p>I'm in the process of incorporating Google sign-in into my app, but I'm getting errors in Android Studio when trying to build the project. I'm including <code>'com.google.android.gms:play-services-auth:9.0.2'</code> as a dependency in my app-level gradle file and <code>'com.google.gms:google-services:2.0.0-alpha6'</code> as a dependency in my project-level gradle file. Building the project gives me the error: <code>Error:Failed to resolve: com.google.android.gms:play-services-measurement:9.0.2</code> with an option to "Install Repository and sync project", but clicking this option does nothing. I have <code>apply plugin: 'com.google.gms.google-services'</code> at the end of the app-level gradle file. There are no other instances where I'm using <code>com.google.android.gms:play-services-*</code> dependencies. I have "Google Play services" installed via the SDK Manager. Any help would be appreciated and I can provide more information as needed.</p>
