I am new to Openfire and smack, therefore I have questions regarding pubsub feature. Actually, I have created a node with setAccessModel as authorize, shown below.
PubSubManager mgr = new PubSubManager(xmpp.getConnection());
try {
LeafNode leaf = mgr.createNode("testNode");
ConfigureForm form = new ConfigureForm(DataForm.Type.submit);
form.setAccessModel(AccessModel.authorize);
form.setDeliverPayloads(true);
form.setNotifyRetract(true);
form.setPersistentItems(true);
form.setPublishModel(PublishModel.open);
leaf.sendConfigurationForm(form);
} catch (SmackException.NoResponseException e) {
e.printStackTrace();
} catch (XMPPException.XMPPErrorException e) {
e.printStackTrace();
} catch (SmackException.NotConnectedException e) {
e.printStackTrace();
}
My question is that when somebody wants to subscribe to above node, how the owner of this node can handle the subscription request? Subscription part is as follows:
PubSubManager mgr = new PubSubManager(xmpp.getConnection());
// Get the node
LeafNode node = null;
try {
node = mgr.getNode("testNode");
node.addItemEventListener(new ItemEventCoordinator());
node.subscribe(senderUser+"#desi.loc");
} catch (SmackException.NoResponseException e) {
e.printStackTrace();
} catch (XMPPException.XMPPErrorException e) {
e.printStackTrace();
} catch (SmackException.NotConnectedException e) {
e.printStackTrace();
}
class ItemEventCoordinator implements ItemEventListener {
#Override
public void handlePublishedItems(ItemPublishEvent items) {
final ItemPublishEvent itemstemp=items;
runOnUiThread(new Runnable() {
#Override
public void run() {
//stuff that updates ui
dspySub.setText("Item: " + itemstemp.getItems());
}
});
}
}
When I set form.setAccessModel(AccessModel.open) every thing works fine. Users can publish and subscribe easily but when its AccessModel is authorize, owner don't listen, or might be I don't know how to handle subscription request at owner side with above piece of code. Kindly guide me.
Jawad, I've just replied another guy' question about listening subscription requests. Please take a look:
How can i listen incoming subscription request in smack openfire android
I really hope that it can help you.
Good luck!

I'm trying to have my android app to be able to send and receive xmpp message using smack but it does not work and the connect command does not return. I have seen several code example but Smack has new versions and the syntax has changed so I might be doing something wrong :
in my build.graddle file I use :
compile "org.igniterealtime.smack:smack-android-extensions:4.3.0"
compile "org.igniterealtime.smack:smack-tcp:4.3.0"
I'm trying to send a message from myaccount321#xabber.org to myaccount456#xabber.org
I'm trying to connect using hot-chilli.net (Idon't mind using some other server))
everything seems to go well until connection.connect() after which the script does not return without triggering any exception.
Please tell me what I'm doing wrong
TIA
public void sendxmpp(){
XMPPTCPConnectionConfiguration config = null;
try {
XMPPTCPConnectionConfiguration.Builder configbuilder = XMPPTCPConnectionConfiguration.builder();
configbuilder.setUsernameAndPassword("myaccount321","myaccount321pw");

configbuilder.setPort(8222);

AbstractXMPPConnection connection = new XMPPTCPConnection(config);
try {
connection.connect();

Chat chat = chatManager.createChat(jid);
chat.sendMessage("Hello");
}
catch (Exception e) {

}
OK I got it, the connection process has to be done in its own thread.
I am making a chat application with smack library and openfire as a server but everytime i exit the chat conversation activity between two users and come back, the whole chat gets erased. I have already enabled archive settings to store one to one messages in the server but i do not know how to implement it in the app.
I want to show chats history in recyclerview by the sender and the receiver in the recyclerview.
currently i have implemented this function which caused error
private void setChatHistory(String entityBareId) {
EntityBareJid jid = null;
try {
jid = JidCreate.entityBareFrom(entityBareId);
} catch (XmppStringprepException e) {
e.printStackTrace();
}
MamManager manager = MamManager.getInstanceFor(mConnection);
MamManager.MamQueryResult r = null;
try {
try {
r = manager.mostRecentPage(jid, 10);
} catch (SmackException.NotConnectedException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
} catch (XMPPException.XMPPErrorException e) {
e.printStackTrace();
} catch (SmackException.NotLoggedInException e) {
e.printStackTrace();
} catch (SmackException.NoResponseException e) {
e.printStackTrace();
}
if (r.forwardedMessages.size() >= 1) //printing first of them
{
Message message = (Message) r.forwardedMessages.get(0).getForwardedStanza();
Log.i("mam", "message received" + message.getBody());
MessagesData data = new MessagesData("send",message.getBody());
mMessagesData.add(data);
mAdapter = new ConversationAdapter(mMessagesData);
recyclerView.setAdapter(mAdapter);
}
}
Error was
Attempt to read from field 'java.util.List org.jivesoftware.smackx.mam.MamManager$MamQueryResult.forwardedMessages' on a null object reference
At r.forwardedmessages.size()>=1.
Thanks in advance
If you want to keep history of conversation, you must save them in database. MAM just for fetching old conversation from server like when you uninstall or logout the app and decide to reinstall and get old messages.
For getting messages from server be sure you already enabled it, then forwarded messages shouldnt be null. here is a guide to enable it.
I am getting a strange error while working with account manager in Smack 4.1 for android.
Below is the code snippet:
am = new AccountManager(connection);
Map<String, String> mp = new HashMap<String, String>();
// adding or set elements in Map by put method key and value
// pair
mp.put("username", "user3");
mp.put("password", "ps3");
mp.put("name", "user3");
mp.put("email", "user3#user.com");
try {
am.createAccount("user3", "user3", mp);
} catch (SmackException.NoResponseException e) {
e.printStackTrace();
} catch (XMPPException.XMPPErrorException e) {
e.printStackTrace();
} catch (SmackException.NotConnectedException e) {
e.printStackTrace();
}
The code I've used to connect to Openfire Server is:
XMPPTCPConnectionConfiguration.Builder configBuilder = XMPPTCPConnectionConfiguration.builder();
configBuilder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
configBuilder.setServiceName("host_name");
configBuilder.setHost("host_name");
configBuilder.setPort(5222);
configBuilder.setCompressionEnabled(false).build();
AbstractXMPPConnection connection = new XMPPTCPConnection(configBuilder.build());
try {
System.out.println("connecting");
connection.setPacketReplyTimeout(10000);
connection.connect();
System.out.println("connected");
SASLAuthentication.unBlacklistSASLMechanism("PLAIN");
SASLAuthentication.blacklistSASLMechanism("DIGEST-MD5");
} catch (SmackException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (XMPPException e) {
e.printStackTrace();
}
and is running perfect.
The exact error is: "Error:(66, 18) error: AccountManager(XMPPConnection) has private access in AccountManager"
I've wasted like 2-3 hours trying to find it but got no answers. I'm a noob so please forgive me if this is a basic question. Also please reply on that as I am stuck and can not move forward.
Thanks alot for the time!!
You need to get an instance from the accountManager that's relevant to your Xmpp connection.
AccountManager ac = AccountManager.getInstance(XMPPConnection connection)
This is what we see from Mopub and other ad networks:
java.io.IOException: Connection failure
com.google.android.gms.ads.identifier.AdvertisingIdClient.g(Unknown
Source)
com.google.android.gms.ads.identifier.AdvertisingIdClient.getAdvertisingIdInfo(Unknown
Source)
They all seem to have the same problem.
The weird thing is that we have no problem getting the advertising id from our app whatsoever with the following source. We get the right advertising id and we have no error logs.
All the SDKs are hitting the same issue (Connection failure).
Any help appreciated.
private void getAdvertisingId(AdvertisingIdHolder receiver) {
AdvertisingIdClient.Info adInfo = null;
String id = null;
boolean isLAT = false;
try {
adInfo = AdvertisingIdClient.getAdvertisingIdInfo(App.getCtx());
id = adInfo.getId();
isLAT = adInfo.isLimitAdTrackingEnabled();
} catch (IOException e) {
SLog.e("error", e);
// Unrecoverable error connecting to Google Play services (e.g.,
// the old version of the service doesn't support getting AdvertisingId).
} catch (GooglePlayServicesNotAvailableException e) {
SLog.e("error", e);
// Google Play services is not available entirely.
} catch (GooglePlayServicesRepairableException e) {
e.printStackTrace();
}
receiver.receive(id, isLAT);
}
I went through trials and errors these days on getting advertising id. Finally I got it!
The connection error can be solved if we pass in getApplicationContext() instead of the context of current activity. Below is my working code:
private void getGaid() {
new Thread(new Runnable() {
#Override
public void run() {
try {
String gaid = AdvertisingIdClient.getAdvertisingIdInfo(
getApplicationContext()).getId();
if (gaid != null) {
Log.d("DEBUG", gaid);
// gaid get!
}
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (GooglePlayServicesRepairableException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (GooglePlayServicesNotAvailableException e) {
e.printStackTrace();
}
}
}).start();
}
getGaid() can be put in onCreate(), onResume(), or onClick() of a view, as long as the thread is called by the main ui thread.
Another thing you may need is to update google play services library to latest version. As the official document here mentioned, IOException is probably caused because the old version of the service doesn't support getting AdvertisingId.
Feel free to comment if there is any other questions.
I made android application that connects to remote server and send some data.
Remote server is Windows application.
Connection method:
private void ConnectToMonitor() {
try {
s = new Socket(SERVER_ADDRESS, TCP_SERVER_PORT);
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
s.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
This works perfectly if server is online. Application is sending data and server is receiving. But if server is offline android app. is blocked. My question is how to handle this? How to continue with application and avoid error even the server is down?
Remember to call this outside the UIThread.
Follow this tutorial. In android all connections need to be managed outside the UIThread, in the tutorial I linked you will find easy ways to post your results back to the UI (handlers, asynctasks...)
Of course we don't know if the problem is about the thread with just the given code, but it is the most usual error.
First remember to set the socket timeout :
mSocket.setSoTimeout(timeout); //in milliseconds
You can however specify different timeout for connection and for all other I/O operations through the socket:
private void connectToMonitor() {
try {
socket = new Socket();
InetAddress[] iNetAddress = InetAddress.getAllByName(SERVER_ADDRESS);
SocketAddress address = new InetSocketAddress(iNetAddress[0], TCP_SERVER_PORT);
socket.setSoTimeout(10000); //timeout for all other I/O operations, 10s for example
socket.connect(address, 20000); //timeout for attempting connection, 20 s
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
socket.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Second, in Android, you should perform any network I/O in separate threads!
As an example, using regular Java Threads :
String threadName = getClass().getName() + "::connect";
new Thread(new Runnable() {
#Override
public void run() {
connectToMonitor();
}
}, threadName).start();
You can set A timeout for the socket. Use Socket.setSoTimeout method
socket.setSoTimeout(timesinmilis);
by using this your socket will throw a socket timout exception. You can catch that and do what you want
