添加新的Google登录到Android应用程序后,Proguard混淆问题

Question

在新的Google Play服务库(8.3.0)中,有一种新的登录方式.此方法涉及添加以下依赖项:

build.gradle(app level): classpath 'com.google.gms:google-services:1.4.0-beta3'

在应用程序级别:

compile 'com.google.android.gms:play-services-auth:8.3.0'

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

在创建minifyEnabled设置为的发布应用版本时false,该应用程序正在发布并正常工作.但是,在启动时创建minifyEnabled设置为true应用程序崩溃的发布版本 时会出现以下异常:

java.lang.RuntimeException: Unable to get provider com.google.android.gms.measurement.AppMeasurementContentProvider: java.lang.ClassNotFoundException: Didn't find class "com.google.android.gms.measurement.AppMeasurementContentProvider" on path: DexPathList[[zip file "/data/app/com.xxx.xxx-1/base.apk"],nativeLibraryDirectories=[/data/app/com.xxx.xxx-1/lib/arm, /vendor/lib, /system/lib]]

我试图将这些设置添加到proguard项目配置中,但它没有帮助(同样的异常一直出现):

-optimizationpasses 5
-keepattributes SourceFile,LineNumberTable,Exceptions, Signature, InnerClasses,*Annotation*
-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.**

我已经为此提交了错误报告。
