This is normally a gradle build problem, try updating your gradle version.

I had a problem due to another package having installed which was creating clashes. As I uninstalled it, worked successfully.

I hope it would help someone else.

I had the same problem and tried a lot but when checked the logs, found some clashes with other application package though having no connection with it. So may someone else would also face the same problem then this solution would help. – Mohammedsalim Shivani Nov 17 '16 at 07:37

Just delete the .gradle folder from the project directory. Restart the Android Studio.

Note: .gradle folder is hidden in your Android Project Directory in MacOS. :)
