Update screen when "all" asynctasks are done
<p>I am using asynctask to do lengthy operations such as DB reads. I want to start a new activity and render its  contents when all the asynch tasks are done. What would be the best way to achieve this? </p>

<p>I know that onPostExecute is used to update screen. But I dont want to update screen unless all ther ayncTasks are done</p>

<p>Please help
Thanks</p>
