Hi, I’m trying to start a chat inside a activity in Android, the idea is to open the connection and start sending e receiving messagem only when the activity is open, to test I send messages to a user in Spark, but I’m having problems, I can send the messages, but only sometimes I can receive then, I don’t know why works only sometimes and neither the conditions, above the entire code of the activity, I created the chatlistener in the overrided method run(), I posted the entire code just in case the problem is in another place.
If someone could help
