Класс android.support.v7.app.ActionBar.Callback уже добавлен в вывод. Удалите дубликаты копий

Question

Я использую Android Studio и Gradle. У меня проблема с v7 ActionBar. Я очищаю и строю свой проект и ту ошибку:

Ошибка: класс android.support.v7.app.ActionBar.Callback уже добавлен в вывод. Удалите дубликаты.

Выполнение не выполнено для задачи ': MobilOnay: dexDebug'. Не могли бы назвать IncrementalTask.taskAction() на задачу ': MobilOnay: dexDebug'

Вы должны удалить андроид-поддержка -v7-appcom pat.jar из вашей папки libs.

Вы добавляете в два раза одну и ту же библиотеку. Достаточно использовать эту зависимость.

compile 'com.android.support:appcompat-v7:18.0.+' 

Вы также можете использовать последнюю версию.

compile 'com.android.support:appcompat-v7:19.0.+'
