I am working on Android Chat app based on Smack 4.1.7. I have created my XMPP related operations on Saperate class said MyXMPP.java. and in my app's Application class i am initializing MyXMPP class objects.
my problem is, suppose we have user 1 and user 2. if user 1 sends message to user 2 then user 2 can get message but cant reply back. means if user 2 trying to reply then user 1 can not get user 2's reply.
in short if user 1 initiates chatting then, only user 1 can send message. user 2 can not send message to user 1 same Vice versa.
my codes are as below,
MyXMPP.java
public class MyXMPP {
static Context context;
static XMPPTCPConnectionConfiguration.Builder xmppConfig;
static XMPPTCPConnection connection;
static MyXMPP myXMPP = null;
static Chat chat;
Roster roster;
ArrayList<Rosters> rosters;
static ChatManager chatManager;
static Application app;
public static synchronized MyXMPP getInstance(Context c) {
app = (Application) c.getApplicationContext();
context = c;
if (myXMPP == null) {
myXMPP = new MyXMPP();
xmppConfig = XMPPTCPConnectionConfiguration.builder();
xmppConfig.setResource(Constants.RESOURCE);
xmppConfig.setServiceName(Constants.SERVICE_NAME);
xmppConfig.setPort(Constants.PORT);
xmppConfig.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
}
return myXMPP;
}
public static synchronized AbstractXMPPConnection getConnectXMPP() {
try {
xmppConfig.setUsernameAndPassword(Constants.USERNAME, Constants.PASSWORD);
XMPPTCPConnection.setUseStreamManagementDefault(true);
connection = new XMPPTCPConnection(xmppConfig.build());
connection.setUseStreamManagement(true);
connection.connect().login();
connection.requestSmAcknowledgement();
