我刚刚下载了Android Studio2，所以我对Android开发方面还很陌生。IDE给了我一个渲染问题：

Rendering Problems
    Failed to load the LayoutLib: com/android/layoutlib/bridge/Bridge : Unsupported major.minor version 52.0 (Details)

详情返回此：

我相信这个问题来自于我的API没有做正确的事情。当我选择下拉框选择另一个API时，我得到的只是23 N预览。我如何解决这个问题，让我使用Android Studio的设计选项卡？

我确实正确安装了JDK（或者我认为是这样）。
