Notification.Builder

public static class Notification.Builder
extends Object

java.lang.Object
   ↳ android.app.Notification.Builder


Builder class for Notification objects. Provides a convenient way to set the various fields of a Notification and generate content views using the platform's notification layout template. If your app supports versions of Android as old as API level 4, you can instead use NotificationCompat.Builder, available in the Android Support library.

Example:

 Notification noti = new Notification.Builder(mContext)
         .setContentTitle("New mail from " + sender.toString())
         .setContentText(subject)
         .setSmallIcon(R.drawable.new_mail)
         .setLargeIcon(aBitmap)
         .build();

A notification in its expanded form can display up to 3 actions, from left to right in the order they were added.

Parameters
icon int: Resource ID of a drawable that represents the action.
title CharSequence: Text describing the action.
intent PendingIntent: PendingIntent to be fired when the action is invoked.
Returns
Notification.Builder
