OngoingActivity

public final class OngoingActivity

Main class to access the Ongoing Activities API. It's created with the Builder. After it's created (and before building and posting the Notification) apply apply needs to be called: 

NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
....
OngoingActivity ongoingActivity = new OngoingActivity.Builder(context, notificationId, builder);
....
ongoingActivity.apply(context);
notificationManager.notify(notificationId, builder.build());
 Note that the notification passed to the Builder is also usen to take defaults if they are not explicitly set on it (see the Builder for details).

Note that if a Notification with that id was previously posted it will be replaced. If you need more than one Notification with the same ID you can use a String tag to differentiate them in both the Builder and notify

Afterward, update can be used to update the status.

If saving the OngoingActivity instance is not convenient, it can be recovered (after the notification is posted) with recoverOngoingActivity

It's worth mentioning that the information provided may be used/redered differently on different SysUIs, so we can only provide a general expectation.
