我正在尝试在Google Play中保存游戏功能的示例 - 收集所有星星2 - 在此处找到：https://github.com/playgameservices/android-basic-samples。
它工作正常，但一旦我启用proguard，我得到以下错误：

我已尝试修改proguard-project文件，但仍然存在错误。
我当前的proguard-project文件：
# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html
# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
