>Please fix the version conflict either by updating the version of the google-services plugins (information about the latest version is available at http://bintray.com/android/android-tools//com.google.gms.google-services/) or updating the version of com.google.android.gms to 12.0.1

This problem occurs when google play services  and its dependencies have different versions, however google play services require its all dependencies of same version.

So, to fix this -

Open build.gradle (Module: app) and go into dependencies section and check all dependencies that starts like com.google.xxx:zyx-zbc:12.0.x;. Now change its version to the version of google play service (generally it is last one).

Now sync the gradle.
