android – non removable notification-ThrowExceptions

Exception or error:

In my app, there is service running on background. I want to notify user that the service is running. But I need that user cannot delete the notification – by pressing clear button or by swipe it out, in notification bar

It means I need to show my notification above Notification area

How to solve:

This is possible but the way you implement it depends on the API level you develop for.

For API levels below 11, you can set Notification.FLAG_NO_CLEAR. This can be implemented like this:

// Create notification
Notification note = new Notification(R.drawable.your_icon, "Example notification", System.currentTimeMillis());

// Set notification message
note.setLatestEventInfo(context, "Some text", "Some more text", clickIntent);

// This notification will not be cleared by swiping or by pressing "Clear all"
note.flags |= Notification.FLAG_NO_CLEAR;

For API levels above 11, or when using the Android Support Library, one can implement it like this:

Notification noti = new Notification.Builder(mContext)
    .setContentTitle("Notification title")
    .setContentText("Notification content")
    .setOngoing(true) // Again, THIS is the important line


To Create Non removable notification just use setOngoing (true);

NotificationCompat.Builder mBuilder =
                         new NotificationCompat.Builder(this)


                        .setContentTitle("My title")


                        .setContentText("Small text with details");


Sound like Notification.FLAG_NO_CLEAR or Notification.FLAG_ONGOING_EVENT is what you are looking for.


To Create Non removable notification just use setOngoing (true);

To Create removable notification just use setOngoing (false);
