android-php ,response is triggered twice sometimes
<p>I am using json response which connects to <a href="http://example.com/test.php" rel="nofollow">http://example.com/test.php</a> I receive response in the listview and its all good,but sometimes the php is triggered  twice , eg: if has mail() function inside it sends once but rarely sends it twice ,I cannot predict when that is happening ,Is it because it does not contain session_start() or is it some other reason? The php has just mail() function.</p>

<p>Thanks in advance.</p>
