NotificationCompat无法解析为类型 [英] NotificationCompat cannot be resolved to a type

问题描述

我是Android的新手，并收到错误消息:"NotificationCompat无法解析为类型"

I am newer to Android and receive the error message: "NotificationCompat cannot be resolved to a type"

MinSDK = 9，TargetSDK = 18，

MinSDK=9, TargetSDK=18,

到目前为止，所有消息来源对于如何解决此问题都含糊不清，只需指出:更新JAR文件"即可.

As of yet, all sources are very vague on how to resolve this issue and simply note: "update the JAR files".

我需要什么JAR，在哪里可以找到它们，以便解决此问题?

What JARs do I need and where can I find them, so that this issue is resolved?
