title: How to execute Async task repeatedly after fixed time intervals
body: <p>How to make Async task execute repeatedly after some time interval just like Timer...Actually I am developing an application that will download automatically all the latest unread greeting from the server and for that purpose I have to check for updates from server after some fixed time intervals....I know that can be easily done through timer but I want to use async task which I think is more efficient for android applications. </p>
