我有一个Android项目（目标= Google API：17）。 我正在使用Proguard，一切正常，直到我添加google-play-services库作为依赖项。 现在我收到以下错误：
java.lang.IllegalArgumentException: Value is not a reference value [proguard.evaluation.value.InstructionOffsetValue]

请帮我这个，

如果您使用Android Studio，则包含ProGuard指令
注意：ProGuard指令包含在Play服务客户端库中以保留所需的类。用于Gradle的Android插件会自动将ProGuard配置文件附加到AAR（Android ARchive）包中，并将该包附加到ProGuard配置中。在项目创建期间，Android Studio会自动为ProGuard创建ProGuard配置文件和build.gradle属性。要在Android Studio中使用ProGuard，必须在build.gradle buildTypes中启用ProGuard设置。有关更多信息，请参阅ProGuard主题。

您未包含Google Play服务Proguard例外： http://developer.android.com/google/play-services/setup.html#Proguard
