XMPP connection keeps getting disconnected android

Question

im using a service to keep my xmpp connection active all the time here, this is the code:

public class XMPPService extends Service { @Override public int onStartCommand(Intent intent, int flags, int startId) { new ConnectionStatus().execute(); return START_STICKY; } @Override public void onCreate() { Log.i("service", "created"); } public class ConnectionStatus extends AsyncTask{ @Override protected Object doInBackground(Object[] params) { XMPPClient.getConnection().addConnectionListener( new AbstractConnectionListener() { public void connectionClosed() { Log.i("connection", "closed"); } public void connectionClosedOnError(Exception e) { Log.i("connection", "closed on error"); } public void reconnectionFailed(Exception e) { Log.i("reconnection", "failed"); } public void reconnectionSuccessful() { if (XMPPClient.getConnection().isAuthenticated()) { Log.i("isauthenticauted : ", String.valueOf(XMPPClient.getConnection().isAuthenticated())); Log.i("reconnection", "succesful"); } else { try { XMPPClient.getConnection().login(new TinyDB(getApplicationContext()).getString("username"), new TinyDB(getApplicationContext()).getString("password")); } catch (XMPPException e) { e.printStackTrace(); } catch (SmackException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } Log.i("reconnection", "succesful"); } } public void reconnectingIn(int seconds) { Log.i("reconnectingIn", String.valueOf(seconds)); } } ); return null; } } @Override public IBinder onBind(Intent intent) { // TODO: Return the communication channel to the service. throw new UnsupportedOperationException("Not yet implemented"); } 

}

but the connection is constantly disconnecting at regular intervals, and I get the following:

  org.jivesoftware.smack.SmackException: Parser got END_DOCUMENT event. This could happen eg if the server closed the connection without sending a closing stream element at org.jivesoftware.smack.tcp.XMPPTCPConnection$PacketReader.parsePackets(XMPPTCPConnection.java:1148) at org.jivesoftware.smack.tcp.XMPPTCPConnection$PacketReader.access$200(XMPPTCPConnection.java:937) at org.jivesoftware.smack.tcp.XMPPTCPConnection$PacketReader$1.run(XMPPTCPConnection.java:952) at java.lang.Thread.run(Thread.java:818) 

after which it connects to the server again, and then I get the following:

 09-07 17:56:03.916 17754-20996/com.sports.unity D/SMACK﹕ SENT (0): `09-07 17:56:04.217 17754-20997/com.sports.unity D/SMACK﹕ RECV (0): <?xml version='1.0'?><stream:stream xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' id='2025993121' from='mm.io' version='1.0' xml:lang='en'><stream:features><c xmlns='http://jabber.org/protocol/caps' hash='sha-1' node='http://www.process-one.net/en/ejabberd/' ver='Kyn00yB1iXiJLUJ0gVvn7tZREMg='/><register xmlns='http://jabber` 

how to keep a stable connection to the xmpp server

Answer 1

This mainly happens when your client is idle for more than the simple timeout (" Idle without connectivity policy ") specified on your server. To do this, you need to implement the XMPP Ping classes in your smack / asmack library, in which you need to send the XMPP Pong in response to the server ping. And you can also implement XMPP reconnection classes.
