stop restarting asynctask on revisiting application
<p>My application simply request the <code>json</code> data from <code>url</code> and displays it in <code>TableLayout</code>. I used <code>asynctask</code> to request the <code>json</code> data and then I use that <code>json</code> data to fill my <code>TableLayout</code>. It works correct but when i press <code>back</code> button and then i again come to application,It again  request the <code>json</code> data by running <code>AsyncTask</code>. I just want to stop calling <code>AsyncTask</code> again.so the <code>TableLayout</code> is filled up with same data twice. so how could i solve this problem?</p>
