Local notification doesn't open the app android

Hi I've implemented local notifications in my game (android) but after the notification appears in the home screen of the phone I click it and it doesn't open the game.

here's the Manifest:

 <?xml version="1.0" encoding="utf-8"?>
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
     package="com.area730.localnotif" >
 
     <uses-sdk android:minSdkVersion="9" />
     <uses-permission android:name="android.permission.VIBRATE" />
 
     <application>
 
         <receiver android:name="com.area730.localnotif.NotificationReciever"></receiver>
 
     </application>
 
 </manifest>
