Android chat using smack

Question asked by eyreena on Oct 2, 2015

Hello  everyone,

Following is  a code snippet from class of Smack library, in some case the number of listeners is zero, and my chat wont works but when the listeners is created chat works,

but i am unable to understand under which conditions the listeners are created successfully, can anyone suggest me the reason .


void deliver(Message message) {

        // Because the collector and listeners are expecting a thread ID with

        // a specific value, set the thread ID on the message even though it

        // probably never had one.




        for (MessageListener listener : listeners) {

            listener.processMessage(this, message);
