java - 将新的 Google 登录添加到 Android 应用程序后的 Proguard 混淆问题

Question

在新的 Google Play 服务库 (8.3.0) 中，有一种执行登录的新方法。此方法涉及添加以下依赖项:

build.gradle(应用级别):类路径 'com.google.gms:google-services:1.4.0-beta3'

在应用层面:

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

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

在 minifyEnabled 设置为 false 的情况下创建发布应用程序版本时，应用程序正在发布并且工作正常。但是，在创建发布版本时minifyEnabled 设置为 true 应用程序在启动时崩溃，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]]

我尝试将这些设置添加到混淆器项目配置中，但没有帮助(同样的异常不断出现):

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