Using Smack, how I can get Nickname/Username from JID using Smake.
Note, the JID is not in my roaster.
Thanks.
May be its too late but for others who are facing this issue
From smack:4.2.0
You can get all parts separately using JID.
if you have JID like abcd#xyzPc- 599
String local = XmppStringUtils.parseLocalpart(userObject.getUserId().toString());
Log.d(TAG, local); // print abcd
String domain = XmppStringUtils.parseDomain(userObject.getUserId().toString());
Log.d(TAG, domain); // print xyzPc-599
You can check code for XmppStringUtils.
Hope will help to someone...
Use the String Utils of Smack to parse the name portion of the JID
Smack Docs String Utils
String name = StringUtils.parseName(JID);
WHen you say it's not in your Roster, how are you being passed the JID? Are you getting it from your message?
we can get nick name using JID but we must add all users in VCARD
String nickname = smackHelper.getNickname(from);
public String getNickname(String jid) throws SmackInvocationException {
VCard vCard = vCardHelper.loadVCard(jid);
return vCard.getNickName();
}
public VCard loadVCard(String jid) throws SmackInvocationException {
VCard vCard = new VCard();
try {
vCard.load(con, jid);
return vCard;
} catch (Exception e) {
throw new SmackInvocationException(e);
}
}

Currently using following code for calling and email features, but it is only working in Android and not working in IOS. Also, I need these features in UWP.
For call:
string phoneno = "1234567890";
Device.OpenUri(new Uri("tel:" + phoneno));
For mail:
string email = "sreejithsree139#gmail.com";
Device.OpenUri(new Uri("mailto:" + email ));
Any package available for this?
Xamarin.Essentials (Nuget) is available as a preview package and contains functionality to both open the default mail app and attach information such as the recipients, subject and the body as well as open the phone dialer with a certain number.
There is also a blog post about Xamarin.Essentials available on blog.xamarin.com.
Edit:
As for your mail issue, Xamarin.Essentials expects an array of strings as recipients so you are able to send mail to multiple people at once. Just pass a string array with one single value.
var recipients = new string[1] {"me#watercod.es"};
If you're using the overload that expects an EmailMessage instance, you are supposed to pass a List of string objects.
In that case, the following should work:
var recipients = new List<string> {"me#watercod.es"};
Updating the complete code for calling and mailing features using Xamarin.Essentials, this might help others.
For call:
try
{
PhoneDialer.Open(number);
}
catch (ArgumentNullException anEx)
{
// Number was null or white space
}
catch (FeatureNotSupportedException ex)
{
// Phone Dialer is not supported on this device.
}
catch (Exception ex)
{
// Other error has occurred.
}
For Mail:
List<string> recipients = new List<string>();
string useremail = email.Text;
recipients.Add(useremail);
try
{
var message = new EmailMessage
{
//Subject = subject,
//Body = body,
To = recipients
//Cc = ccRecipients,
//Bcc = bccRecipients
};
await Email.ComposeAsync(message);
}
catch (Exception ex)
{
Debug.WriteLine("Exception:>>"+ex);

Hello to make a call in UWP:
if (Windows.Foundation.Metadata.ApiInformation.IsTypePresent("Windows.ApplicationModel.Calls.PhoneCallManager"))
{
Windows.ApplicationModel.Calls.PhoneCallManager.ShowPhoneCallUI("123", "name to call");
}
To send a Text:
private async void ComposeSms(Windows.ApplicationModel.Contacts.Contact recipient,
string messageBody,
StorageFile attachmentFile,
string mimeType)
{
var chatMessage = new Windows.ApplicationModel.Chat.ChatMessage();
chatMessage.Body = messageBody;
if (attachmentFile != null)
{
var stream = Windows.Storage.Streams.RandomAccessStreamReference.CreateFromFile(attachmentFile);
var attachment = new Windows.ApplicationModel.Chat.ChatMessageAttachment(
mimeType,
stream);
chatMessage.Attachments.Add(attachment);
}
var phone = recipient.Phones.FirstOrDefault<Windows.ApplicationModel.Contacts.ContactPhone>();
if (phone != null)
{
chatMessage.Recipients.Add(phone.Number);
}
await Windows.ApplicationModel.Chat.ChatMessageManager.ShowComposeSmsMessageAsync(chatMessage);
}
as found in Microsoft documentation here: Compose SMS documentation
==> So you can make (If not already done) a shared service interface in your Xamarin app, then the implementation with these codes in your UWP app...

To send an email in UWP, you can refer to the Microsoft documentation too:

Using a plugin
Else you can use a Xamarin plugin:
documentation: Xamarin cross messaging plugin
Nuget: Nuget plugin package
In our app, we are doing the phone calling with a DependencyService.
Therefore in our PCL, we have
public interface IPhoneCall
{
void Call(string number);
}
On the iOS side, the following method does the calling:
public void Call(string number)
{
if (string.IsNullOrEmpty(number))
return;
var url = new NSUrl("tel:" + number);
if (!UIApplication.SharedApplication.OpenUrl(url))
{
var av = new UIAlertView("Error",
"Your device does not support calls",
null,
Keys.Messages.BUTTON_OK,
null);
av.Show();
}
}
If don't want to wait for the Xamarin essentials that is still in pre-release as of today, you can use this open source plugin. It works on iOS, Android and UWP. There is a sample from the github documentation :
// Make Phone Call
var phoneDialer = CrossMessaging.Current.PhoneDialer;
if (phoneDialer.CanMakePhoneCall)
phoneDialer.MakePhoneCall("+27219333000");
// Send Sms
var smsMessenger = CrossMessaging.Current.SmsMessenger;
if (smsMessenger.CanSendSms)
smsMessenger.SendSms("+27213894839493", "Well hello there from Xam.Messaging.Plugin");
var emailMessenger = CrossMessaging.Current.EmailMessenger;
if (emailMessenger.CanSendEmail)
{
// Send simple e-mail to single receiver without attachments, bcc, cc etc.
emailMessenger.SendEmail("to.plugins#xamarin.com", "Xamarin Messaging Plugin", "Well hello there from Xam.Messaging.Plugin");
// Alternatively use EmailBuilder fluent interface to construct more complex e-mail with multiple recipients, bcc, attachments etc.
var email = new EmailMessageBuilder()
.To("to.plugins#xamarin.com")
.Cc("cc.plugins#xamarin.com")
.Bcc(new[] { "bcc1.plugins#xamarin.com", "bcc2.plugins#xamarin.com" })
.Subject("Xamarin Messaging Plugin")
.Body("Well hello there from Xam.Messaging.Plugin")
.Build();
emailMessenger.SendEmail(email);
}
This is regarding Sendgrid incoming mail webhook, I have referred this URL SendGrid incoming mail webhook - how do I secure my endpoint, and got some idea how to go about this, but, as I am new to MVC / WebAPI, could anyone give me the controller method code snippet to catch the JSON format HTTP post and save to my application folder.
This is the solution I found after googling and with slight modifications:
[HttpPost, HttpGet]
[EnableCors(origins: "*", headers: "*", methods: "*")]
public async Task Post()
{
if (Request.Content.IsMimeMultipartContent("form-data"))
try
{
//To get complete post in a string use the below line, not used here
string strCompletePost = await Request.Content.ReadAsStringAsync();
HttpContext context = HttpContext.Current;
string strFrom = context.Request.Form.GetValues("from")[0];
string strEmailText = context.Request.Form.GetValues("email")[0];
string strSubject = context.Request.Form.GetValues("subject")[0];
//Not useful I guess, because it always return sendgrid IP
string strSenderIP = context.Request.Form.GetValues("sender_ip")[0];
}
catch (Exception ex)
{
}
}
I tried, retrieving the values as
String to = context.Request.Params["to"];
but, the value returned is not consistent, i.e. most of the times it is returning null and occasionally returns actual value stored in it.
If anyone have a better solution, please let me know.
Thank you
If for some reason ["to"] doesn't work for you, try to get ["envelope"] value,
context.Request.Form.GetValues("envelope")[0]
which looks like
{"to":["emailto#example.com"],"from":"emailfrom#example.com"}
I am trying to send a file through chat using openfire on the server and the smack java library.
This is the output I get:
Status :: Error Error :: null Exception :: service-unavailable(503) Is
it done? true
Here are my sender and receiver functions:
public void fileTransfer(String fileName, String destination) throws XMPPException {
// Create the file transfer manager
FileTransferManager manager = new FileTransferManager(connection);
FileTransferNegotiator.setServiceEnabled(connection,true);
// Create the outgoing file transfer
OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(destination);
// Send the file
transfer.sendFile(new File(fileName), "You won't believe this!");
try {
Thread.sleep(10000);
}
catch(Exception e){}
System.out.println("Status :: " + transfer.getStatus() + " Error :: " + transfer.getError() + " Exception :: " + transfer.getException());
System.out.println("Is it done? " + transfer.isDone());
}
public void fileReceiver(final boolean accept, final String fileName) {
// Create the file transfer manager
final FileTransferManager manager = new FileTransferManager(connection);
// Create the listener
manager.addFileTransferListener(new FileTransferListener() {
public void fileTransferRequest(FileTransferRequest request) {
// broadcast something here. Wheather users want to accept file
// Check to see if the request should be accepted
if(accept) {
// Accept it
IncomingFileTransfer transfer = request.accept();
try {
transfer.recieveFile(new File(fileName));
System.out.println("File " + fileName + "Received Successfully");
//InputStream input = transfer.recieveFile();
} catch (XMPPException ex) {
Logger.getLogger(XmppManager.class.getName()).log(Level.SEVERE, null, ex);
}
} else {
// Reject it
request.reject();
}
}
});
}
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 that can be done 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 jid is destination.
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");
Using agsXMPP to connect to Google Cloud Messaging XMPP API for the purpose of sending notification to Android devices.
The connection is established OK, but on SASL start, after sending the PLAIN auth element, the server stops responding, and closes the connection after a further 20 seconds.
Base64 decoding the auth example from the documentation page (http://developer.android.com/google/gcm/ccs.html) shows login values of:
126200347933#projects.gcm.android.com12620034793#projects-ga-.android.comAIzaSyB3rcZNkfnqKdFb9mhzCBiYpORDA2JWWtw
Where as agsXMPP is (correctly I think) encoding the string, to give something like:
[ProjectID]\40gcm.googleapis.com[**API*KEY*PASSWORD**]
Note the \40 in my version instead of the # in the Google example - could this make a difference?
I'm expecting either a success or failure message, no response at all is difficult to debug. Could this at character be responsible for some failure, or does Google's implementation of XMPP just not provide the correct responses.
UPDATED:
I answered below, essentially, yes, Google can't handled the encoded # character because it doesn't support that XMPP extension.
After some more testing, I added a new SaslFactory mechanism in agsXMPP and bound it to use the username without encoding (part of extension http://xmpp.org/extensions/xep-0106.html, which Google doesn't support), and then on SaslStartEvent - specify that I want to use that mechanism instead of the inbuilt plain one. - and now the connection will continue normally.
xmpp = new XmppClientConnection();
xmpp.UseSSL = true;
xmpp.UseStartTLS = false;
xmpp.Server = "gcm.googleapis.com";
xmpp.ConnectServer = "gcm.googleapis.com";
xmpp.Port = 5235;
/* Other connection settings /*
SaslFactory.AddMechanism("MyPLAINMechanism", typeof(MyPlainMechanismClass));
xmpp.OnSaslStart += (sender, args) =>
{
args.Auto = false;
args.Mechanism = "MyPLAINMechanism";
args.ExtentedData = new GcmPlainSaslExtendedData
{
Username = "MY UNENCODED USERNAME"
};
};
Then we define the MyPlainMechanismClass which inherits from the Mechanism in agsXMPP, the source code is the same as the original PlainSaslMechanism except the line where the username is input - you can pass in an unencoded username using the ExtendedData property on args.
public class MyPlainMechanismClass: Mechanism
{
private XmppClientConnection m_XmppClient = null;
public GcmPlainSaslMechanism()
{
}
public override void Init(XmppClientConnection con)
{
m_XmppClient = con;
// <auth mechanism="PLAIN" xmlns="urn:ietf:params:xml:ns:xmpp-sasl">$Message</auth>
m_XmppClient.Send(new agsXMPP.protocol.sasl.Auth(agsXMPP.protocol.sasl.MechanismType.PLAIN, Message()));
}
public override void Parse(Node e)
{
// not needed here in PLAIN mechanism
}
private string Message()
{
// NULL Username NULL Password
StringBuilder sb = new StringBuilder();
//sb.Append( (char) 0 );
//sb.Append(this.m_XmppClient.MyJID.Bare);
sb.Append((char)0);
//sb.Append(this.Username);
sb.Append(((GcmPlainSaslExtendedData) this.ExtentedData).Username);
sb.Append((char)0);
sb.Append(this.Password);
byte[] msg = Encoding.UTF8.GetBytes(sb.ToString());
return Convert.ToBase64String(msg, 0, msg.Length);
}
}
Our custom ExtendedData object which we use to pass in custom arguments, such as an unencoded username in this case.
public class GcmPlainSaslExtendedData : agsXMPP.Sasl.ExtendedData
{
public string Username { get; set; }
}
this is what I have so far:
void xmppConnection_OnReadXml(object sender, string xml)
{
if (xml.Contains(XmlTags.PhotoOpen))
{
int startIndex = xml.IndexOf(XmlTags.PhotoOpen) + XmlTags.PhotoOpen.Length;
int length = xml.IndexOf(XmlTags.PhotoClose) - startIndex;
string photoHash = xml.Substring(startIndex, length);
}
}
I guess I can't undo the hash, but I want to the get a person's avatar/photo. How do I achieve this?
You need to handle the VCard events and responses from XMPP connection:
private void vcardToolStripMenuItem_Click(object sender, EventArgs e)
{
RosterNode node = rosterControl.SelectedItem();
if (node != null)
{
frmVcard f = new frmVcard(node.RosterItem.Jid, XmppCon);
f.Show();
}
}
The above is from the miniclient solution example from the AGSXMPP download. Note, it happens when a user request a VCARD for a user. You can initiate that request whenever you want, however.
private void VcardResult(object sender, IQ iq, object data)
{
if (InvokeRequired)
{
// Windows Forms are not Thread Safe, we need to invoke this :(
// We're not in the UI thread, so we need to call BeginInvoke
BeginInvoke(new IqCB(VcardResult), new object[] { sender, iq, data });
return;
}
if (iq.Type == IqType.result)
{
Vcard vcard = iq.Vcard;
if (vcard!=null)
{
txtFullname.Text = vcard.Fullname;
txtNickname.Text = vcard.Nickname;
txtBirthday.Text = vcard.Birthday.ToString();
txtDescription.Text = vcard.Description;
Photo photo = vcard.Photo;
if (photo != null)
picPhoto.Image = vcard.Photo.Image;
}
}
}
That is what happens when someone requests the VCARD information from XMPP and the IQ type matches the proper data. You can thenpull the photo from vcard.Photo.
You trigger the pull with:
VcardIq viq = new VcardIq(IqType.get, new Jid(jid.Bare));
con.IqGrabber.SendIq(viq, new IqCB(VcardResult), null);
The first line there is the request to the XMPP server, that the VCARD form uses to request user information.
The second line there, sets up another grabber (callback of sorts), that the form uses to wait for the information to arrive, and then parse out the necessary information. IN this case, the grabber is in a new form, so that the main application doesn't have to worry about parsing that information.
You can look at the entire source by extracting the AGSXMPP zip file to your local drive, and looking in the Samples\VS2008\miniclient folder.
