如何使用Google Play服务配置proguard

Question

我有多个dex文件的标准问题：

  

错误：将字节码转换为dex时出错：原因：   com.android.dex.DexException：多个dex文件定义   LCOM /谷歌/机器人/克/ R $阵列;

我正在开发一个依赖于Google Play服务（版本：9.4.0）的aar库。运行proguard时没有问题，但是当我将此库添加到应用程序时会出现dex问题。

Proguard文件（基于Android-proguard）：

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose
-dontoptimize
-dontpreverify

-keepattributes *Annotation*
-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService

-keepclasseswithmembernames class * {
    native <methods>;
}


-keepclassmembers public class * extends android.view.View {
   void set*(***);
   *** get*();
}

-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keepclassmembers class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator CREATOR;
}

-keep class **.R
-keepclassmembers class **.R$* {
    public static <fields>;
}
-keepattributes InnerClasses

-keep public class * {
    public protected <fields>;
    public protected <methods>;
}

-dontwarn android.support.**

-keep class android.support.annotation.Keep

-keep @android.support.annotation.Keep class * {*;}

-keepclasseswithmembers class * {
    @android.support.annotation.Keep <methods>;
}

-keepclasseswithmembers class * {
    @android.support.annotation.Keep <fields>;
}

-keepclasseswithmembers class * {
    @android.support.annotation.Keep <init>(...);
}
