title: NotificationCompat cannot be resolved to a type
body: <p>I am newer to Android and receive the error message: "NotificationCompat cannot be resolved to a type"</p>
  
  <p>MinSDK=9, TargetSDK=18,</p>
  
  <p>As of yet, all sources are very vague on how to resolve this issue and simply note: "update the JAR files".</p>
  
  <p>What JARs do I need and where can I find them, so that this issue is resolved?</p>
