添加新的Google登錄到Android應用程序后，Proguard混淆問題

Question

在新的Google Play服務庫（8.3.0）中，有一種新的登錄方式。 此方法涉及添加以下依賴項：

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

在應用程序級別：

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

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

在創建minifyEnabled設置為false的發布應用版本時，該應用程序正在發布並正常工作。 但是，在創建minifyEnabled設置為true的發布版本時，應用程序在啟動時崩潰，但出現以下異常：

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]]

我試圖將這些設置添加到proguard項目配置中，但它沒有幫助（同樣的異常一直出現）：

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

我已經為此提交了錯誤報告 。
