How exactly to use Notification.Builder

gistfile1.java

Intent notificationIntent = newIntent(ctx, YourClass.class);
PendingIntent contentIntent = PendingIntent.getActivity(ctx,
		YOUR_PI_REQ_CODE, notificationIntent,
		PendingIntent.FLAG_CANCEL_CURRENT);
NotificationManager nm = (NotificationManager) ctx
		.getSystemService(Context.NOTIFICATION_SERVICE);
Resources res = ctx.getResources();
Notification.Builder builder = newNotification.Builder(ctx);
builder.setContentIntent(contentIntent)
		.setSmallIcon(R.drawable.some_img)
		.setLargeIcon(
				BitmapFactory.decodeResource(res,
						R.drawable.some_big_img))
		.setTicker(res.getString(R.string.your_ticker))
		.setWhen(System.currentTimeMillis()).setAutoCancel(true)
		.setContentTitle(res.getString(R.string.your_notif_title))
		.setContentText(res.getString(R.string.your_notif_text));
Notification n = builder.build();
nm.notify(YOUR_NOTIF_ID, n);
