Proguard error while generating signed apk

Question

I am using latest google play services library project and I am targeting android 17 (4.2.2) in my app and the min SDK version is android 11 (3.0).I have used mail functionality to send mail using GMail sender, push notifications and also included google play library services jar file and library project to support google maps and also google analytics to track the app screen usability. While signing the apk the proguard displays this error "com.google.android.gms.cast.TextTrackStyle: can't find referenced class android.view.accessibility.CaptioningManager". This is my project properties.txt file
