You can also use other solution by using NotificationManagerCompat. try this code

NotificationManagerCompat mNotifyMgr =
    NotificationManagerCompat.from(mCtx);

if (mNotifyMgr != null) {
    mNotifyMgr.notify(1, mBuilder.build());
}

where mCtx is context or you can getApplicationContext()

You forgot this mate:

note.setLatestEventInfo(this, "contentTitle", "contentText", pi);

You need to change your code to :

NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

Just remove the . before the getSystemService() method.

the compiler is looking for a variable named "NotificationManager" since you used the . operator next to it.

You can do this like this way if you want

String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);

        int icon = R.drawable.ic_launcher;
        CharSequence tickerText = "Hello";
        long when = System.currentTimeMillis();

        Notification notification = new Notification(icon, tickerText, when);

        Context context = getApplicationContext();
        CharSequence contentTitle = "My notification";
        CharSequence contentText = "Hello World! " + android_id;
        Intent notificationIntent = new Intent(this,
                ExpMapLatLongActivity.class);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                notificationIntent, 0);

        notification.setLatestEventInfo(context, contentTitle, contentText,
                contentIntent);

        mNotificationManager.notify(HELLO_ID, notification);

In your code 

NotificationManager manager = (NotificationManager).getSystemService(Context.NOTIFICATION_SERVICE);

Change it to

NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
