With this .gradle build successfully for me

apply plugin: 'com.android.application'

android {
compileSdkVersion 21
buildToolsVersion "21.1.1"

defaultConfig {
    applicationId "com.cooperbros.myapplication"
    minSdkVersion 9
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }
}   

dependencies {

  compile fileTree(dir: 'libs', include: ['*.jar'])
  compile 'com.android.support:appcompat-v7:21.0.2'
  compile 'com.android.support:gridlayout-v7:21.0.0'
