Error code 503 on transferring file using xmpp

I am trying to send an image file using smack and openfire xmpp. For this I am using FileTransferManager class. To use FileTransferManager class I am using asmack-android-6.jar. I followed this link to do file sharing. This issue is also shared in comments below on this tutorial but no good resolution is given to this issue. Then I searched over stack overflow, Many Developers have asked this question but only 1-2 have got replies that they have accepted, others not.
I studied all the answers that I found, tried all the ways that google gave me but still unable to solve this problem.
The code I used is:
d.findViewById(R.id.btnsendphoto).setOnClickListener(
new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (!filepath.equals("")) {
ServiceDiscoveryManager sdm = ServiceDiscoveryManager
.getInstanceFor(connection);
if (sdm == null) {
sdm = new ServiceDiscoveryManager(
connection);
Log.e("service discovery", "SDM");
sdm.addFeature("http://jabber.org/protocol/disco#info");
sdm.addFeature("jabber:iq:privacy");
}
mFileTransferManager = new FileTransferManager(
connection);
/*
* OutgoingFileTransfer transfer =
* mFileTransferManager
* .createOutgoingFileTransfer
* ("98c6d889473a6fae#pc/Smack");
*/
String to = connection.getRoster()
.getPresence("98c6d889473a6fae#pc")
.getFrom();
OutgoingFileTransfer transfer = mFileTransferManager
.createOutgoingFileTransfer(to);
File file = new File(filepath);
try {
//[configureProviderManager](http://paste.ubuntu.com/9932239/)
configureProviderManager(connection);
transfer.sendFile(file, "test_file");
} catch (XMPPException e) {
e.printStackTrace();
}
while(!transfer.isDone()) {
Log.d("status", transfer.getStatus().toString());
Log.d("percent", new Long(transfer.getBytesSent()).toString());
if (transfer.getStatus() == Status.error) {
Log.e("percent", "Error " + new Long(transfer.getBytesSent()).toString() + " " + transfer.getError() + " " + transfer.getException());
transfer.cancel();
}
if(transfer.getStatus().equals(Status.refused))
System.out.println("refused " + transfer.getError());
else if( transfer.getStatus().equals(Status.error))
System.out.println(" error " + transfer.getError());
else if(transfer.getStatus().equals(Status.cancelled))
System.out.println(" cancelled " + transfer.getError());
else
System.out.println("Success");
}
}
d.dismiss();
}
});
The logcat I got is very big, so I gave link of that. So can anyone tell what mistake I am making or can suggest what amendment I make to achieve task

This problem got solved using this link answer don't know why its downvoted. Lemme share answer here also

I had same problem, I investigated the stanza and solved it this way.
Many people use "/Smack" or "/Resource" as resource part in jid, but it can be configured also the another way.
Resource path is changing with every presence changed of user. Lets say we want to send image to this user:
"user1#mydomain"
You must add "/Resource" part to this jid and it become this:
user1#mydomain/Resource
But /Resource path is changing with presence so you must follow every presence change to update resource path.
Best way is to get user presence is in roster listener and in presencheChanged() method you get last user resource part like this:
Roster roster=getRoster();
roster.addRosterListener(new RosterListener() {
#Override
public void entriesAdded(Collection<Jid> addresses) {
Log.d("entriesAdded", "ug");
context.sendBroadcast(new Intent("ENTRIES_ADDED"));
}
#Override
public void entriesUpdated(Collection<Jid> addresses) {
Log.d("entriesUpdated", "ug");
}
#Override
public void entriesDeleted(Collection<Jid> addresses) {
Log.d("entriesDeleted", "ug");
}
#Override
public void presenceChanged(Presence presence) {
Log.d("presenceChanged", "ug");
//Resource from presence
String resource = presence.getFrom().getResourceOrEmpty().toString();
//Update resource part for user in DB or preferences
//...
}
});
}
Resource string will be some generated string like "6u1613j3kv" and jid will become:
user1#mydomain/6u1613j3kv
That means that you must create your outgoing transfer like this:
EntityFullJid jid = JidCreate.entityFullFrom("user1#mydomain/6u1613j3kv");
OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(jid)
transfer.sendFile(new File("DirectoryPath"), "Description");
And that is how i have solved my problem with file transfer on smack and Openfire.
In your case form jid like this:
String to = connection.getRoster().getPresence("98c6d889473a6fae#pc").getFrom();
String Resource = connection.getRoster().getPresence("98c6d889473a6fae#pc").getFrom().getResourceOrEmpty().toString();
OutgoingFileTransfer transfer = mFileTransferManager.createOutgoingFileTransfer(to + "/" + resource);
Also to mention you must add following properties in your Openfire server:
xmpp.proxy.enabled - true
xmpp.proxy.externalip - MY_IP_ADDRESS
xmpp.proxy.port - 7777
Just to mention, I am using Openfire 4.0.2 and Smack 4.2.2.
Also this can be configured the easy way, just set the resource on
XMPPTCPConnectionConfiguration.Builder .
like
XMPPTCPConnectionConfiguration.Builder configurationBuilder =
XMPPTCPConnectionConfiguration.builder();
configurationBuilder.setResource("yourResourceName");

How to clear errors in xmpp chat program in android

Hi I am creating a chat application using xmpp. My problem is that while running the project a dialog box appears showing 'your project contain errors fix then and run', but there is no errors shown in project explorer, a warning is sign is shown(hope it doesn't effect rnuning a project). The console page is showing like this :
[2013-09-25 10:25:01 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/kenai/jbosh/AbstractAttr;

Most of the time this happens due to the multiple copies of android-support-v4 libraries in your project and and dependent project.
First try to delete the other android-support-v4 library and make it same for all.
if this works for you then its good other wise follow the below steps thats gonna work with you
1- List item
2-Open Project Build Path,
3-Select "Libraries" tab,
4-Remove all library except the Android Library
5-Adding all required JARs Files
And you are Done.

This error occurs you will better understand by this example - In case you download any project in this project environment means SDK updated in API LEVEL 15 and such type of project you import in your work-space and at this time point to be noted your SDK updated in API LEVEL
19 at this time fixed project setup and it will goes Build Path at this you just add external
libraries android-support-v4 then this problem has occurs due to the multiple copies of android-support-v4/google-play-services if you use Google map libraries in your project.
i hope so you will better understand.
Thankys

aSmack as a service

Basically I have a Main class running the entire project. The code is working perfectly although once the App is unfocused it becomes inactive. I was wondering how I would go about making it a service. One that would startup at boot.
The app will be a one way message system for notifications. I.E.
Desktop Client -> Openfire Server -> Android XMPP Service -> Storage (DB) -> Android GUI for display
As I've said, the Code is working (Connect, Login, Receive) but isn't a service.
I could use the BEEM source but it's too featured and interlaced. I'm after a lightweight service.
The code:
public class MainActivity extends Activity {
public static final String HOST = "fire.example.com";
public static final int PORT = 5222;
public static final String SERVICE = "example.com";
public static final String USERNAME = "metest#fire.example.com";
public static final String PASSWORD = "mepass";
private XMPPConnection connection;
private ArrayList<String> messages = new ArrayList<String>();
private Handler mHandler = new Handler();
private ListView listview;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listview = (ListView) this.findViewById(R.id.listMessages);
setListAdapter();
connect();
}
/**
* Called by Settings dialog when a connection is establised with

*/
public void setConnection(XMPPConnection connection) {
this.connection = connection;
if (connection != null) {
// Add a packet listener to get messages sent to us
PacketFilter filter = new MessageTypeFilter(Message.Type.chat);
connection.addPacketListener(new PacketListener() {
#Override
public void processPacket(Packet packet) {
Message message = (Message) packet;
if (message.getBody() != null) {
String fromName = StringUtils.parseBareAddress(message.getFrom());
Log.i("XMPPChatActivity ", " Text Recieved " + message.getBody() + " from " + fromName);

So basically, How do I make this a service

i guess this example at the given link would give you the idea for making it a service. http://android.codeandmagic.org/small-test-of-asmack-xmpp-client-library/

You need to utilise the Android Service Framework.
You could check out GTalk SMS source as they utilize a service and is open source. (Main Service is the service they use to handle the connection etc. ) though it is also very complicated.
I would highly recommend you check out the basics of utilizing a service in Android.
Remember a service does not create a new thread, everything is still done on the UI thread so if you want to perform long running tasks in the background then you'll also need to implement an asynctask or executor service.

Old question, but I'll put my answer anyways.
You need to create a service, start it and put your code of aSmack connection in the service, not in any activity. The service will retain the connection even when the app is not in foreground. I am using this method in one of my client's app and it's working great.
Also, make sure you use a Handler or AsyncTask in the service to create the socket connection in another non-UI thread. Android will not allow you to create the connection in UI thread anyways.

Establishing ServerSocket connection

I used this code in my application-
public class BorderCastList extends Activity {
private VideoView video;
private ServerSocket server;
private MediaController media;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Settings window for translucent state
// this.getWindow().setFormat(PixelFormat.TRANSLUCENT);
this.setContentView(R.layout.video);
new Thread(new Runnable() {
#Override
public void run() {
try {
Log.i("test", "before info ServerSocket");
server = new ServerSocket(8050)
Log.i("test", "after info ServerSocket");
Log.i("ip:" + server.getLocalSocketAddress() + "----port: "
+ server.getLocalPort(), "");
Log.i("service ip: " + server.getInetAddress(), "");
Log.i("Server build success************", "");
// Socket socket = server.accept();
} catch (Exception e) {
Log.i("aaa", "bbbb");
e.printStackTrace();
}
}
}).start();
)
Why am I getting the log output Log.i("test", "before info ServerSocket"); but not Log.i("test", "after info ServerSocket");
Log.i("ip:" + server.getLocalSocketAddress() + "----port: "+ server.getLocalPort(), "");
Log.i("server ip: " + server.getInetAddress(), "");
Log.i("Server build success************", "");
Why does it not execute after new ServerSocket(8050)?

On Galaxy Nexus Android 4.1.2 your code creates and binds the socket without problems. Do you have uses-permission android:name="android.permission.INTERNET" in your manifest? Otherwise just expect the stack trace and also bbbb about the aaa.

Can I get online users in my friend list via Smack?

Can i get online users in my friend list via Smack API? Is it possible?
I am working on app which have chat between users. I had successfully created chat application example just entering name of friend and send chat, but now I want online friends list.

Roster roster = xmppConnection.getRoster();
Collection<RosterEntry> entries = roster.getEntries();
Presence presence;
for(RosterEntry entry : entries) {
presence = roster.getPresence(entry.getUser());
System.out.println(entry.getUser());
System.out.println(presence.getType().name());
System.out.println(presence.getStatus());
}

XMPPConnection.addConnectionCreationListener(new ConnectionCreationListener() {
#Override
public void connectionCreated(Connection arg0) {
Log.i(TAG, "receive xmpp connection : " + arg0);
connection = arg0;
roster = arg0.getRoster();
Collection<RosterEntry> entries = roster.getEntries();
Presence presence;
Log.e(TAG, "user count" + entries.size());
for (RosterEntry entry : entries) {
presence = roster.getPresence(entry.getUser());
Log.i(TAG, "" + entry.getUser());
Log.i(TAG, "" + presence.getType().name());
Log.i(TAG, "" + presence.getStatus());
}
}
});
So at the start of your program register that XMPPConnection listener, usually it take few seconds to receive connection object.
But it will work only if you will use creatEntry only in that case rooster will see those created users.
To creat entry using Roster use next code:
try {
rooster.createEntry("name", "user_id", null);
} catch (XMPPException e) {
e.printStackTrace();
}
I didn't use any group, and with success see user on second device.

Presence presence = roster.getPresence("tom#jabber.org");
if (presence.getType() == Presence.Type.AVAILABLE) {
// Tom is online...
}
reference from this link

Use the presence.getMode() method to get Mode of User.
Mode is enum and its value can be chat, available, away, xa, dnd.
