You could add google   to repositories block  allprojects       repositories           jcenter           maven               url  https   github com uPhyca stetho-realm raw master maven-repo                     maven               url  https   jitpack io                    google

Appart from setting maven source url to your gradle  I would suggest to add both design and appcompat libraries  Currently the latest version is 26 1 0  maven       url  https   maven google com           compile  com android support appcompat-v7 26 1 0  compile  com android support design 26 1 0

Have you added the google maven endpoint      Important  The support libraries are now available through Google s Maven repository  You do not need to download the support repository from the SDK Manager  For more information  see Support Library Setup     Add the endpoint to your build gradle file   allprojects       repositories           jcenter           maven               url  https   maven google com                      Which can be replaced by the shortcut google   since Android Gradle v3   allprojects       repositories           jcenter           google             If you already have any maven url inside repositories  you can add the reference after them  i e    allprojects       repositories           jcenter           maven               url  https   jitpack io                    maven               url  https   maven google com

you must add in your MODULE-LEVEL build gradle file with     module-level build gradle file repositories       maven           url  https   maven google com             see  Google s Maven repository  I have observed that when I use Android Studio 2 3 3 I MUST add repositories maven url  https   maven google com    in MODULE-LEVEL build gradle   In the case of Android Studio 3 0 0 there is no need for the addition in module-level build gradle  It is enough the addition in project-level build gradle which has been referred to in the other posts here  namely     project-level build gradle file allprojects    repositories       jcenter       maven           url  https   maven google com           name  Google                UPDATE 11-14-2017  The solution  that I present  was valid when I did the post  Since then  there have been various updates  even with respect to the site I refer to   and I do not know if now is valid  For one month I did my work depending on the solution above  until I upgraded to Android Studio 3 0 0
