Notification Without Pending Intent

I need to create a notification,which will display in the top but it should not navigate to any page,should not have any onclick function. here is the code which i have used. notif

Solution 1:

Use Intent wihtout having component, like below

PendingIntentcontentIntent= PendingIntent.getActivity(
    getApplicationContext(),
    0,
    newIntent(), // add this
    PendingIntent.FLAG_UPDATE_CURRENT);

This is provide a way where use can't open an Activity.
