如何解决 Android 3.6 中的渲染视图问题

Question

谁能帮我解决这个问题。最近将Android 3.5升级到3.6，然后布局文件报错：
Render problem: Exception raised during rendering (Details).
虽然我创建了一个新项目，如下图所示，但在布局文件中只有一个 TextClock 视图。 Image

堆栈跟踪：

编辑：这是 Android Studio 错误。有关更新信息，请参阅 issueTracker。

将此添加到 build.gradle

android{
.....
 compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}
