How do I edit the text of foreground service notifications?

TL;DR Summary

I'd like to run a timer in a foreground notification. I thought I could use the setContextText command for this, but it doesn't change the text in the notification at all.

Hi everyone

I'd like to make a timer that continues to run on the lock screen after the power button is pressed. I thought I could use a foreground notification for this and used code from this page:

In particular, I thought I could modify the following lines of code:

  Notification.Builder notification = new Notification.Builder(this, CHANNELID)
                .setContentText("Activity Recognition is running....")
                .setContentTitle("Obesity Point");

However, it seems setContentText and setContentTitle do nothing. No matter what I put in the quotation marks, my notification title is " Timer is running" and the text is "Tap for more information or to stop the app".

How do I change the text and title?

Thanks

Nevermind. The problem was that I didn't set an icon with .setSmallIcon. The text changes now that I've done that.
