How to send

when the client got 'unclean' disconnection from the WiFi / GSM,

doesn't send

<resume xmlns='urn:xmpp:sm:3' h='some-sequence-number' previd='some-long-sm-id'/>

stanza after reconnecting

always:

D/SMACK﹕ SENT (0): <enable xmlns='urn:xmpp:sm:3' resume='true'/>

D/SMACK﹕ RECV (0): <enabled xmlns='urn:xmpp:sm:3' id='e3de0d2c-49ac-42f1-b78c-6f2bfcb045e0' resume='true' max='60' location='jiazhangquan.im.etiantian.net' />

if the client got 'unclean' disconnection from the WiFi / GSM ,

what should I do when the client reconnection ?

just  connection.connect();   connection.login(); ?

my code:

                        XMPPTCPConnectionConfiguration.Builder builder = XMPPTCPConnectionConfiguration.builder();

                        builder.setHost(service);

                        builder.setPort(port);

                        builder.setUsernameAndPassword(jid, pwd);

                        builder.setServiceName(service);

                        builder.setDebuggerEnabled(true);

                        builder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);

                        if(connection == null) {

                            connection = new XMPPTCPConnection(builder.build());

                        }

                        XMPPTCPConnection.setUseStreamManagementDefault(true);

                        XMPPTCPConnection.setUseStreamManagementResumptiodDefault(true);

                        connection.setUseStreamManagement(true);

                        connection.setUseStreamManagementResumption(true);

                        try {

                              connection.connect();                           

                              connection.login();

                        } catch (Exception e) {

                            e.printStackTrace();

                        }

build.gradle:

dependencies {

    compile fileTree(dir: 'libs', include: ['*.jar'])

    compile "org.igniterealtime.smack:smack-android-extensions:4.1.0"

    compile "org.igniterealtime.smack:smack-tcp:4.1.0"
