Я получаю сообщение об ошибке при попытке создать прогард-версию моего приложения для Android.И я не могу найти это в Google.

Ошибка заключается в:

Я импортирую wpsapi.jar в мой проект как внешний jar в [Project] / libs/

Вот proguard.cfg

Я не знаю точной причины этой проблемы, но я столкнулся с некоторыми странными проблемами при использовании Proguard. Я переключился на последнюю версию Proguard, и это решило все мои проблемы. Чтобы изменить версию Proguard, вам необходимо заменить папку /tools / proguard на более новую версию Proguard.
