我正在使用Android Studio构建应用程序，使用以下依赖项：
- Play服务 ：
compile 'com.google.android.gms:play-services:5.2.08' - AppCompat v7 ：
compile 'com.android.support:appcompat-v7:21.0.0' - 支持CardView ：
compile 'com.android.support:cardview-v7:21.0.0' - 支持RecyclerView ：
compile 'com.android.support:recyclerview-v7:21.0.0'
在构建我的应用程序时，我遇到以下错误:
