GetSearchForm returns null when using UserSearch in XMPP using aSmack

Question

I have this code, almost unchanged from the examples:

UserSearchManager usm = new UserSearchManager(conn); Form searchForm = usm.getSearchForm("search.myserver.com"); Form answerForm = searchForm.createAnswerForm(); answerForm.setAnswer("Username", true); answerForm.setAnswer("search", contact.getJid()); ReportedData data = usm.getSearchResults(answerForm, "search.myserver.com"); 

This works fine in the Desktop environment using the Smack library, but I can't get it to work on Android (where I need to use asmack).

The problem is that searchForm is null since getSearchForm returns null. This seems rather strange since I cannot find any documentation about which cases this method should return null.

The server is Openfire if that helps.

Update 04/2014

The original answer below contains old and outdated information. Since aSmack 0.8 is no longer required to manually configure the provider manager. Calling SmackAndroid.init(Context) , when you are prompted to execute the aSmack README command, performs all the necessary initializations.

Original answer

In the end, the problem was global for all asmack. This seems to be a known issue: the smack.providers file, usually located in the / META -INF folder in regular versions of smack, cannot be downloaded to Android because it is packaged in a jar. Therefore, all providers must be initialized manually, as shown in Mike Ryan's answer in this thread: http://community.igniterealtime.org/message/201866#201866

I deleted material that did not work for me, and this is the result.

 public void configure(ProviderManager pm) { // Private Data Storage pm.addIQProvider("query","jabber:iq:private", new PrivateDataManager.PrivateDataIQProvider()); // Time try { pm.addIQProvider("query","jabber:iq:time", Class.forName("org.jivesoftware.smackx.packet.Time")); } catch (ClassNotFoundException e) { Log.w("TestClient", "Can't load class for org.jivesoftware.smackx.packet.Time"); } // Roster Exchange pm.addExtensionProvider("x","jabber:x:roster", new RosterExchangeProvider()); // Message Events pm.addExtensionProvider("x","jabber:x:event", new MessageEventProvider()); // Chat State pm.addExtensionProvider("active","http://jabber.org/protocol/chatstates", new ChatStateExtension.Provider()); pm.addExtensionProvider("composing","http://jabber.org/protocol/chatstates", new ChatStateExtension.Provider()); pm.addExtensionProvider("paused","http://jabber.org/protocol/chatstates", new ChatStateExtension.Provider()); pm.addExtensionProvider("inactive","http://jabber.org/protocol/chatstates", new ChatStateExtension.Provider()); pm.addExtensionProvider("gone","http://jabber.org/protocol/chatstates", new ChatStateExtension.Provider()); // XHTML pm.addExtensionProvider("html","http://jabber.org/protocol/xhtml-im", new XHTMLExtensionProvider()); // Group Chat Invitations pm.addExtensionProvider("x","jabber:x:conference", new GroupChatInvitation.Provider()); // Service Discovery # Items pm.addIQProvider("query","http://jabber.org/protocol/disco#items", new DiscoverItemsProvider()); // Service Discovery # Info pm.addIQProvider("query","http://jabber.org/protocol/disco#info", new DiscoverInfoProvider()); // Data Forms pm.addExtensionProvider("x","jabber:x:data", new DataFormProvider()); // MUC User pm.addExtensionProvider("x","http://jabber.org/protocol/muc#user", new MUCUserProvider()); // MUC Admin pm.addIQProvider("query","http://jabber.org/protocol/muc#admin", new MUCAdminProvider()); // MUC Owner pm.addIQProvider("query","http://jabber.org/protocol/muc#owner", new MUCOwnerProvider()); // Delayed Delivery pm.addExtensionProvider("x","jabber:x:delay", new DelayInformationProvider()); // Version try { pm.addIQProvider("query","jabber:iq:version", Class.forName("org.jivesoftware.smackx.packet.Version")); } catch (ClassNotFoundException e) { // Not sure what happening here. } // VCard pm.addIQProvider("vCard","vcard-temp", new VCardProvider()); // Offline Message Requests pm.addIQProvider("offline","http://jabber.org/protocol/offline", new OfflineMessageRequest.Provider()); // Offline Message Indicator pm.addExtensionProvider("offline","http://jabber.org/protocol/offline", new OfflineMessageInfo.Provider()); // Last Activity pm.addIQProvider("query","jabber:iq:last", new LastActivity.Provider()); // User Search pm.addIQProvider("query","jabber:iq:search", new UserSearch.Provider()); // SharedGroupsInfo pm.addIQProvider("sharedgroup","http://www.jivesoftware.org/protocol/sharedgroup", new SharedGroupsInfo.Provider()); // JEP-33: Extended Stanza Addressing pm.addExtensionProvider("addresses","http://jabber.org/protocol/address", new MultipleAddressesProvider()); // FileTransfer pm.addIQProvider("si","http://jabber.org/protocol/si", new StreamInitiationProvider()); pm.addIQProvider("query","http://jabber.org/protocol/bytestreams", new BytestreamsProvider()); // Privacy pm.addIQProvider("query","jabber:iq:privacy", new PrivacyProvider()); pm.addIQProvider("command", "http://jabber.org/protocol/commands", new AdHocCommandDataProvider()); pm.addExtensionProvider("malformed-action", "http://jabber.org/protocol/commands", new AdHocCommandDataProvider.MalformedActionError()); pm.addExtensionProvider("bad-locale", "http://jabber.org/protocol/commands", new AdHocCommandDataProvider.BadLocaleError()); pm.addExtensionProvider("bad-payload", "http://jabber.org/protocol/commands", new AdHocCommandDataProvider.BadPayloadError()); pm.addExtensionProvider("bad-sessionid", "http://jabber.org/protocol/commands", new AdHocCommandDataProvider.BadSessionIDError()); pm.addExtensionProvider("session-expired", "http://jabber.org/protocol/commands", new AdHocCommandDataProvider.SessionExpiredError()); 

}

I just commented on a couple of lines and voila. This must be called before creating an XMPPConnection using a line like this:

  configure(ProviderManager.getInstance()); 

Now I have to deal with my other problems, but at least this problem has been resolved :)
