android studio新建hello world时出现Rendering Problems

The following classes could not be instantiated:    
    - android.support.v7.internal.widget.ActionBarOverlayLayout 
java.lang.ClassNotFoundException: android.support.v4.view.ViewPropertyAnimatorListener
    at org.jetbrains.android.uipreview.ModuleClassLoader.load(ModuleClassLoader.java:127)
    at com.android.tools.idea.rendering.RenderClassLoader.findClass(RenderClassLoader.java:53)

…………

大部分是说添加v4 support, 进行安装，但是实际是

res/values/styles.xml 文件里

<!-- Base application theme. -->
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
</style>

少了个Base……
