I got the same problem.
Check you don't have any errors on the bottom of android studio. I got one with sdk build. If you got the same click on the link in error log.

Roll up Main menu -> Tools.
Choose Android.
Click on 'Apply' button and 'OK'. Wait for a while (gradle progress-bar on the bottom).
I hope that I solve your problem.
