Google Play services is missing

I set up a project with admob as this tutorial say, but got no ads shown.

Here is my log (level: info):

11-01 11:11:45.530 4852-4852/com.xxx W/GooglePlayServicesUtil: Google Play services is missing.

And settings:

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"
    defaultConfig {
        applicationId "com.xxx"
        minSdkVersion 9
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.0'
    compile 'com.android.support:design:23.1.0'
    compile 'com.google.android.gms:play-services-ads:8.1.0'
}

What should I do?

Hi there,

From the log it seems we're getting complaints that Google Play services is missing. That should not be possible because you already have the com.google.android.gms:play-services-ads:8.1.0 line as a Gradle dependency, which should take care of integrating the Play services library into your app.

Just so I get more context:

1. Are you able to replicate the problem when compiling and running our sample app?  If your implementation differs, what are the notable differences (you can post code snippets to demonstrate them)?
2. Are there any network problems at the time of the ad request?

Thanks,
