I'm using Smack 4.1.7 in my Android app, and I can't figure out, how to properly shutdown an XMPPTCPConnection when exiting (pressing back from my main activity). Doing conn.disconnect() closes Smack Packet Writer and Smack Packet Reader daemon threads, but Smack-Ping, Smack-Incoming Processor, Smack-Single Threaded Executor and Smack-Remove Callbacks daemon threads remain running. When I launch my app again and establish the connection, another pack of these daemon threads is created, and so on.
Trying to debug, I ended up with this test code in my IntentService:
XMPPTCPConnection conn = new XMPPTCPConnection(
"project #", //$NON-NLS-1$
"api key") //$NON-NLS-1$
conn = null;
catch (Exception e)
As far as I understand, conn is eligible for finalization, but finalize() is not invoked. For now, I use the solution, given in Not closing smack threads by disconnect (4.1.0-alpha1-SNAPSHOT), but I think there should be a better way.
So, what's the proper way of closing a connection?
Any help would be greatly appreciated.
