android - Remote-server-error(502) when there is no network connection -

this how found connection between xmpp client , server , log in background service:

public class messageservice extends service { private string tag = "messageservice"; private xmppconnection connection; private final ibinder mbinder = new mybinder(); @override public ibinder onbind(intent arg0) { // todo auto-generated method stub homecoming mbinder; } public int onstartcommand(intent intent, int flags, int startid) { log.d(tag, "started"); new connect().execute(""); homecoming start_sticky; } private class connect extends asynctask<string, void, string> { @override protected string doinbackground(string... params) { connectionconfiguration connectionconfiguration = new connectionconfiguration( settingsdm.ip_address, settingsdm.port); xmppconnection connection = new xmppconnection( connectionconfiguration); log.i(tag, "getting ready connect..."); seek { connection.connect(); log.i(tag, "connected " + connection.gethost()); } grab (xmppexception ex) { log.e(tag, "failed connect " + connection.gethost()); log.e(tag, ex.tostring()); setconnection(null); } seek { connection.login(settingsdm.test_username, settingsdm.test_password); log.i(tag, "logged in " + connection.getuser()); //setconnection(connection); } grab (xmppexception ex) { log.e(tag, "failed log in " + settingsdm.test_username); log.e(tag, ex.tostring()); setconnection(null); } homecoming null; } } }

this works okay when there network connection. when there's no network connection however, i'd expect exception caught in catch(xmppexception e). doesn't caught , app crashes. background service crashes , attempts restart couple of times keeps crashing.

below error log:

how prevent background service , app crashing when there's no network connection available, rather maintain checking until there's active network connection available?

you have java.net.connectexception , should utilize exception instead of xmppexception
