原因是Android读不到/META-INF下的配置文件,需要手工配置。


	public static 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");
		}

		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

		// 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's 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());

		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());
	}

在new XMPPConnection前,调用:


configure(ProviderManager.getInstance());

搜索好友:


try {
			UserSearchManager search = new UserSearchManager(XmppTool.getConnection());
			Form searchForm = search.getSearchForm("search.fhp");
			Form answerForm = searchForm.createAnswerForm();
			answerForm.setAnswer("Username", true);
			answerForm.setAnswer("search", et_username.getText().toString());
			org.jivesoftware.smackx.ReportedData data = search.getSearchResults(answerForm, "search.fhp");

			Iterator it = data.getRows();
			Row row = null;
			String ansS = "";
			while (it.hasNext()) {
				row = it.next();
				ansS += row.getValues("Username").next().toString() + "\n";
				System.out.println(ansS);
				// Log.i("Username",row.getValues("Username").next().toString());
			}
//			Toast.makeText(this, ansS, Toast.LENGTH_SHORT).show();
		} catch (Exception e) {
			e.printStackTrace();
//			Toast.makeText(this, e.getMessage() + " " + e.getClass().toString(), Toast.LENGTH_SHORT).show();
		}

searchService要与openfire服务器设置一致
