现在我试图按照这个教程：Set up a GCM Client App on Android

我补充说

1. Add the dependency to your project’s top-level build.gradle:
   classpath 'com.google.gms:google-services:1.4.0-beta3'
2. Add the plugin to your app-level build.gradle:
   apply plugin: 'com.google.gms.google-services'

然后我补充说：

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

现在,当我尝试同步,清理或重建.毕业证明我已经成功了.

错误：
当我尝试运行应用程序并选择设备.我得到这个错误：

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

这是我应用级build.gradle的最后一个版本：

在尝试由@JBirdVegas提供的答案后,我得到这个错误：

这是毕业日志：

Note: the configuration refers to the unknown method 'void attachBaseContext(android.content.Context)' in class 'com.emse.emseportal3.App'
Note: there were 1 references to unknown class members.
      You should check your configuration for typos.
Note: there were 14 classes trying to access annotations using reflection.
      You should consider keeping the annotation attributes
      (using '-keepattributes *Annotation*').
      (http://proguard.sourceforge.net/manual/troubleshooting.html#attributes)
Note: there were 20 classes trying to access generic signatures using reflection.
      You should consider keeping the signature attributes
      (using '-keepattributes Signature').
      (http://proguard.sourceforge.net/manual/troubleshooting.html#attributes)
Note: there were 3 classes trying to access enclosing classes using reflection.
      You should consider keeping the inner classes attributes

Note: there were 15 unresolved dynamic references to classes or interfaces.
      You should check if you need to specify additional program jars.

Note: there were 33 accesses to class members by means of introspection.
      You should consider explicitly keeping the mentioned class members
