here screenshot more clarification:

you need add intent category notification.intent_category_notification_preferences activity you'd launch through androidmanifest. simple example like:

    <activity android:name="com.example.packagename.yoursettingsactivity" >          <intent-filter>             <action android:name="android.intent.action.main" />             <category android:name="android.intent.category.notification_preferences" />         </intent-filter>     </activity>
