需要帮助在 AndroidStudio2.3.3 中设置 Kotlin
Need help to setup Kotlin in AndroidStudio2.3.3
在我的 Android Studio 2.3.3 中，我安装了 Kotlin 插件，然后创建了一个 kotlin class activity。当我为那个 Activity 完成 运行 时，我得到了 ClassNotFoundException。我确认我确实在清单文件中添加了新的 Activity。
我第一次使用 Android 尝试使用 Kotlin，不确定 gradle 文件中是否需要更改任何内容以使用 Kotlin。
下面是我的错误日志：

您还需要将 kotlin 插件添加到根项目 build.gradle 和应用程序模块 build.gradle。
