Delete all the notifications on click

Question

in my app I'm creating 3 notifications (with id 0,1, 2) depending on some data.

I use

 setCancel(true);

on the notification in order to let the system cancel it on user click. I would like to cancell all the notifications (id 0,1,2) on the userclick on one of them. Is this possible?

This is my code about notification creation:

    NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    Intent notificationIntent = new Intent(context, ActivityMain.class);
    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_CANCEL_CURRENT);

    Notification.Builder builder = new Notification.Builder(context);
    Notification notification = null;

    builder.setContentTitle(title)
           .setContentIntent(contentIntent);

    notification = new Notification.BigTextStyle(builder).bigText(mex).build();

    notificationManager.notify(id, notification);

Answer 1

Take a look at the NotificationManager#cancelAll method

Answer 2

You can use NotificationManager.cancel(int id) to cancel your notifications when handling the Intent from any of the notifications.
