生成签名apk时出现Proguard错误

Question

我正在使用最新的google play服务库项目，我在我的应用程序中定位android 17（4.2.2），而min SDK版本是android 11（3.0）。我使用邮件功能使用GMail发件人发送邮件，推送通知，还包括谷歌播放库服务jar文件和库项目，以支持谷歌地图和谷歌分析，以跟踪应用程序屏幕的可用性。在签署apk时，proguard显示此错误＆＃34; com.google.android.gms.cast.TextTrackStyle：无法找到引用的类android.view.accessibility.CaptioningManager＆＃34;。这是我的项目properties.txt文件
