java.lang.NoClassDefFoundError: com.google.android.gms.internal.zzpt$zza

Question

I'm developing an Android app that involves authenticating the user using the GoogleApiClientBuilder class. The error occurs during runtime when I hit this part of my code:

GoogleApiClient.Builder builder = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(Plus.API)
            .addScope(Plus.SCOPE_PLUS_LOGIN);

This works perfectly fine on Android 5.0.1 but when I try it on API level 19 (Kitkat), I get this error:

java.lang.NoClassDefFoundError: com.google.android.gms.internal.zzpt$zza

After doingh some research I found it may have been Proguard stripping away the necessary classes but whether I enable or disable minifyEnabled, it doesn't work:

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

Then I did some more research and figured maybe it as a multiDex issue but I enabled it and I'm even compiling it as one of my dependencies

defaultConfig {
    applicationId "com.tubealert.tubealert"
    minSdkVersion 17
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
    multiDexEnabled = true
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    configurations { all*.exclude group: 'com.google.guava', module: 'guava' }
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.android.support:cardview-v7:21.0.0'
    compile 'com.android.support:recyclerview-v7:22.+'
    compile 'com.android.support:support-v4:22.2.0'
    compile 'com.android.support:multidex:1.0.0'
    compile 'com.google.android.gms:play-services:7.5.0'
    compile 'com.google.apis:google-api-services-youtube:v3-rev134-1.20.0'
    compile 'com.google.gdata:core:1.47.1'
}

So as of no it only works on Lollipop but nothing lower than that.. Please help me if you can!

Figured it out. Just had to follow every single step in setting up google play services! Silly mistake on my end.
