Image/banner in android notification

Notifications are important part of android system interface. Each and every new notification first comes in notification area. And then are shown in notification drawer/tray.

You can create a notification using NotificationCompat.builder.build(). All the particulars about the notification are set using NotificationCompat.builder object. You can set icons to be shown, ringtone etc for a notification. But with the material design changes in API level 21, there are much more to it. Now

Notifications are now available on the device lock screen, while sensitive content can still be hidden behind it.
High-priority notifications received while the device is in use now use a new format called heads-up notifications.
Expanded view to add more data to your notification.

But here we will discuss only how to add a image to the notification.

Expanded View

You can now add extra lines to the messages or a image in this view. For adding a image/ banner you have to add the style in your earlier NotificationCompat.builder object.

Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
                PendingIntent.FLAG_ONE_SHOT);

Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

NotificationCompat.Builder notificationBuilder;
            
Bitmap remote_picture = null;
NotificationCompat.BigPictureStyle notiStyle = new NotificationCompat.BigPictureStyle();
try {
      remote_picture = BitmapFactory.decodeStream((InputStream) new URL("http://myserver.com/image123").getContent());
    } catch (IOException e) {
      e.printStackTrace();
    }
notiStyle.bigPicture(remote_picture);
            
notificationBuilder = new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.notification)
                    .setContentTitle("Title of notification")
                    .setContentText("Second line text")
                    .setLargeIcon(icon)
                    .setAutoCancel(true)
                    .setSound(defaultSoundUri)
                    .setContentIntent(pendingIntent)
                    .setStyle(notiStyle);
       
NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());

Intent intent = new Intent(this, MainActivity.class);

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,

PendingIntent.FLAG_ONE_SHOT);

Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

NotificationCompat.Builder notificationBuilder;

Bitmap remote_picture = null;

NotificationCompat.BigPictureStyle notiStyle = new NotificationCompat.BigPictureStyle();

try {

remote_picture = BitmapFactory.decodeStream((InputStream) new URL("http://myserver.com/image123").getContent());

} catch (IOException e) {

e.printStackTrace();

}

notiStyle.bigPicture(remote_picture);

notificationBuilder = new NotificationCompat.Builder(this)

.setSmallIcon(R.drawable.notification)

.setContentTitle("Title of notification")

.setContentText("Second line text")

.setLargeIcon(icon)

.setAutoCancel(true)

.setSound(defaultSoundUri)

.setContentIntent(pendingIntent)

.setStyle(notiStyle);

NotificationManager notificationManager =

(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

notificationManager.notify(0, notificationBuilder.build());

And thats all you can see your notification with image but only on devices with API level 21 or above.
