Ошибка: атрибут "тема" уже определен

Я использую Android-студию для создания приложения. Я использую следующие зависимости:

• игровые сервисы: compile 'com.google.android.gms:play-services:5.2.08'
• app combat v7: compile 'com.android.support:appcompat-v7:21.0.0'
• поддержка Cardview: compile 'com.android.support:cardview-v7:21.0.0'
• поддержка просмотра Recycler: compile 'com.android.support:recyclerview-v7:21.0.0'

При создании моего приложения возникает следующая ошибка:

app/build/intermediates/exploded-aar/com.google.android.gms/play-services/5.2.08/res/values/wallet_attrs.xml
