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false的发布应用版本时,该应用程序正在发布并正常工作.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,但出现以下异常：

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.**
解决方法
我已经提交了
bug report for this.
