Gradle sync failed while creating android app in intellij 16

I'm using Intellij IDEA 2016.3.4 on ubuntu 14.04 LTS to develop android applications. An error- gradle sync failed, missing android extension is occurring.

I'm using sdk platform 25.0.2, kotlin version 1.0.6. This is the line that is throwing an error:

apply plugin: 'kotlin-android'

and the error message is:

Error:(16, 0) Extension with name 'android' does not exist. Currently registered extension names: [ext] Open File

I'm lost. Please can anyone help me out. A detailed solution would be much appreciated!

EDIT 1: Here is the build.gradle code

apply plugin: 'com.android.application'

android {

    compileSdkVersion 25
    buildToolsVersion "25.0.2"

defaultConfig {

    applicationId "com.example.gogol.myapplication"
    minSdkVersion 15
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

}

buildTypes {

    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }
}

dependencies {

  compile fileTree(dir: 'libs', include: ['*.jar'])
  androidTestCompile('com.android.support.test.espresso:espresso-core:2.0',  {
     exclude group: 'com.android.support', module: 'support-annotations'
 })

  compile 'com.android.support:appcompat-v7:25.1.1'
  testCompile 'junit:junit:4.12'
}

EDIT 2: here is build.gradle root project

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

buildscript {

ext.kotlin_version = '1.0.6'

repositories {
    jcenter()
}

dependencies {

    classpath 'com.android.tools.build:gradle:2.2.0'

    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    // NOTE: Do not place your application dependencies here; they belong

    // in the individual module build.gradle files

}
  }

apply plugin: 'kotlin-android'

allprojects {
  repositories {
    jcenter()
  }
}

task clean(type: Delete) {
   delete rootProject.buildDir
}

repositories {    
    mavenCentral()
}

dependencies {

  compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" 
  compile 'com.android.support:appcompat-v7:25.1.1'
  compile 'com.android.support:support-annotations:25.1.1'
}

android {
  sourceSets {

    main.java.srcDirs += 'src/main/kotlin'
  }

  compileSdkVersion 25
  buildToolsVersion '25.0.2'
 }

Add apply plugin: 'android' in your root build.gradle file.

After that your build.gradle file looks like

buildscript {

  ext.kotlin_version = '1.0.6'

  repositories {
      jcenter()
  }

  dependencies {

    classpath 'com.android.tools.build:gradle:2.2.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
  }
}

apply plugin: 'android'
apply plugin: 'kotlin-android'

allprojects {
  repositories {
    jcenter()
  }
}

task clean(type: Delete) {
   delete rootProject.buildDir
}

repositories {    
    mavenCentral()
}

dependencies {

  compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" 
  compile 'com.android.support:appcompat-v7:25.1.1'
  compile 'com.android.support:support-annotations:25.1.1'
}

android {

  sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
  }

  compileSdkVersion 25
  buildToolsVersion '25.0.2'
}
