Mein Projekt funktionierte perfekt mit den folgenden Bibliotheken:

// Support libraries
compile 'com.android.support:support-v4:23.1.0'
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:cardview-v7:23.1.0'
compile 'com.android.support:recyclerview-v7:23.1.0'
// Other stuff
compile 'com.jakewharton:butterknife:7.0.1'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.google.code.gson:gson:2.3'
compile 'com.squareup.retrofit:retrofit:1.9.0'
compile 'com.afollestad:material-dialogs:0.7.8.1'
compile 'com.jpardogo.materialtabstrip:library:1.1.0'
compile 'com.melnykov:floatingactionbutton:1.3.0'
compile 'com.code-troopers.betterpickers:library:2.0.0'
compile 'com.loopj.android:android-async-http:1.4.9'
compile 'com.squareup.okhttp:okhttp:2.5.0'
compile 'com.facebook.fresco:fresco:0.7.0'

Jetzt habe ich versucht, diesem Tutorial zu folgen: Richten Sie eine GCM-Client-App auf Android ein

Ich fügte hinz

Fügen Sie die Abhängigkeit zum Build.gradle der obersten Ebene Ihres Projekts hinzu:
classpath 'com.google.gms:google-services:1.4.0-beta3' Fügen Sie das Plugin zu Ihrem Build.gradle auf App-Ebene hinzu:
apply plugin: 'com.google.gms.google-services'

Dann habe ich hinzugefügt:

compile "com.google.android.gms:play-services:8.1.0"

Now, wenn ich versuche, zu synchronisieren, zu säubern oder neu zu erstellen. Gradle zeigt mir, dass es erfolgreich ist.

DER FEHLER Wenn ich versuche, die App auszuführen und ein Gerät auszuwählen. Ich bekomme diesen Fehler:

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.transform.api.TransformException: java.util.zip.ZipException: duplicate entry: android/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoIcsImpl.class

Dies ist die letzte Version von build.gradle auf App-Ebene:

apply plugin: 'com.google.gms.google-services'

achdem ich die Antwort von @JBirdVegas ausprobiert habe, habe ich folgenden Fehler erhalten:

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
