...
}

My app level build.gradle looks like this

apply plugin: 'com.android.application'

android {
compileSdkVersion 24
buildToolsVersion "24.0.2"

defaultConfig {
    applicationId "my.package.name"
    minSdkVersion 16
    targetSdkVersion 24
    versionCode 1
    versionName "1.0-debug"
    multiDexEnabled true
    testInstrumentationRunner    "android.support.test.runner.AndroidJUnitRunner"

}

packagingOptions {
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/NOTICE'

}
buildTypes {
    release {
        shrinkResources true
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
dexOptions {
    preDexLibraries = false;
}
sourceSets { main { java.srcDirs = ['src/main/java'] } }
}

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:24.2.0'
compile 'com.android.support:design:24.2.0'
compile 'com.android.support:support-v13:24.2.0'

androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2') {
    // Necessary if your app targets Marshmallow (since Espresso
    // hasn't moved to Marshmallow yet)
    exclude group: 'com.android.support', module: 'support-annotations'
}
androidTestCompile('com.android.support.test:runner:0.5') {
    // Necessary if your app targets Marshmallow (since the test  runner
