Here is my build.gradle file:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
   repositories {
       jcenter()
   }
   dependencies {
       classpath 'com.android.tools.build:gradle:1.0.0'

       // NOTE: Do not place your application dependencies here; they belong
       // in the individual module build.gradle files
   }
}

allprojects {
   repositories {
       jcenter()
   }
}


But when I click on run I am getting error
