Android : java.lang.NoSuchMethodError - Notification.Builder

I am using version android 4.0.3 but still i am problem with Notification.Builder

In my search i found the notification.builder will start supporting from API level 11+ and android device version 4.x which is API level 14+

so can any one tell me what's the problem with this.

notification = new Notification.Builder(this)

.setContentTitle(title).build();
