我启动openFire并用spark测试它一切正常但是当我尝试在android studio中连接smack 4.2.0时出现此错误:

Ljavax /命名/目录/ InitialDirContext;

我的依赖是这样的:

编译"org.igniterealtime.smack:smack-java7:4.2.0"compile"org.igniterealtime.smack:smack -tcp:4.2.0"compile"org.igniterealtime.smack:smack-im:4.2.0"compile" org.igniterealtime.smack:smack-extensions:4.2.0"compile"org.igniterealtime.smack:smack-android-extensions:4.2.0"compile"org.igniterealtime.smack:smack-bosh:4.2.0"

当从依赖项中删除这个:"编译org.igniterealtime.smack:smack-java7:4.2.0"并添加它:compile"org.igniterealtime.smack:smack-android:4.2.0"我的依赖项变成这样:

编译'com.android.support:appcompat-v7:24.0.0'compile"org.igniterealtime.smack:smack-android:4.2.0"compile"org.igniterealtime.smack:smack -tcp:4.2.0"compile" org.igniterealtime.smack:smack-im:4.2.0"compile"org.igniterealtime.smack:smack-extensions:4.2.0"compile"org.igniterealtime.smack:smack-android-extensions:4.2.0"compile" org.igniterealtime.smack:咂嘴波什:4.2.0"

我收到此错误:

org.jivesoftware.smack.SmackException $ ConnectionException:以下地址失败:'192.168.209.2:5222'失败,原因是:de.measite.minidns.hla.ResolutionUnsuccessfulException:要求192.168.209.2.IN A产生错误响应NX_DOMAIN,'192.168.209.2:5222'失败,原因是:de.measite.minidns.hla.ResolutionUnsuccessfulException:要求192.168.209.2.在AAAA中产生了错误响应NX_DOMAIN

当我尝试conn.connect()时出现错误的代码部分是这样的:

XMPPTCPConnectionConfiguration config = null;  
            try {  
                config = XMPPTCPConnectionConfiguration.builder()  
                        .setUsernameAndPassword("admin", "thepass")  
                        .setXmppDomain("192.168.1.3")  
                        .setHost("192.168.209.2")  
                        .setPort(5222)  
                        .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)  
                        .build();  
            } catch (Exception e) {  
                e.printStackTrace();  
            }  
                AbstractXMPPConnection conn1 = new XMPPTCPConnection(config);  
                conn1.setReplyTimeout(60000);  
                conn1.setPacketReplyTimeout(60000);  
                conn1.connect();
