How do I match a Google Play Services revision with an install version?

Question

Android SDK Manager notified me this morning that there was a new Google Play Services release to download: revision 18. So how do I find the corresponding long version number to put in my build.gradle file? All my test devices are running version 5.0.84, so I tried updating

compile 'com.google.android.gms:play-services:4.4.52'

to

compile 'com.google.android.gms:play-services:5.0.84'

But that resulted in an error:

Gradle 'MyApp' project refresh failed: Could not find com.google.android.gms:play-services:5.0.84. Required by: {my app} Gradle settings

I'm running Android Studio 0.5.2 and building for API19 (I haven't upgraded to Android L/API20 yet): maybe that's the issue? But in general, how do you match a revision number shown in SDK Manager (e.g. 18) with a version code for build.gradle (e.g. 5.0.84)?

Here's my full build.gradle in case it helps:

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion "19.1.0"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }

    // Avoid "Duplicate files copied in APK" errors when using Jackson
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'
    }
}

dependencies {
    // Was "compile 'com.android.support:support-v4:+'" but this caused build errors when L SDK released
    compile 'com.android.support:support-v4:19.1.0'
    compile fileTree(dir: 'libs', include: ['*.jar'])

    // Support for Google Cloud Messaging
    // Was "compile 'com.android.support:appcompat-v7:+'" but this caused build errors when L SDK released
    compile 'com.android.support:appcompat-v7:19.1.0'
    compile 'com.google.android.gms:play-services:5.0.84'

    // Jackson
    compile 'com.fasterxml.jackson.core:jackson-core:2.3.3'
    compile 'com.fasterxml.jackson.core:jackson-annotations:2.3.3'
    compile 'com.fasterxml.jackson.core:jackson-databind:2.3.3'
}

OK, I haven't quite managed to find a mapping of one to the other, but I've managed the next best thing which is to see a list of Play Services long version numbers installed on my development machine.

For Windows, it's in [android-sdk]\extras\google\m2repository\com\google\android\gms\play-services (where [android-sdk] is the path to your Android SDK folder).

On a Mac, it's inside the Android.app package: browse to sdk/extras/google/m2repository/com/google/android/gms/play-services

The latest version on my machine was 5.0.77 (not 5.0.84), and putting that in my build.gradle worked fine.

Here's the kind of thing you should see at that location:

What I did in my project was download google play service and open the project structure > dependencies tab and click on the plus button and choose google play service. I dont have to care about the version anymore
