How to connect to security disabled ejabberd using smack-android?

Question

I'm having problems connecting to my ejabberd 2.1.11 server using smack 4.1.0-beta2. I thought it had something to do with SSL certificates and not wanting to deal with that stuff I'm just running ejabberd without starting TLS. I know that's working bc I'm able to connect to ejabberd using psi without warning me about some self-signed certificate.

Anyways, I'm using the following ConnectionConfiguration's

XMPPTCPConnectionConfiguration.Builder configBuilder = XMPPTCPConnectionConfiguration.builder();
configBuilder.setUsernameAndPassword("username", "password");
configBuilder.setServiceName("myapp.ddns.net");
configBuilder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
configBuilder.setCompressionEnabled(false);
AbstractXMPPConnection xmppConnection = new XMPPTCPConnection(configBuilder.build());

So when I try xmppConnection.connect(), I get the following exceptions

02-05 01:01:42.965  17047-17047/net.ddns.myapp W/DNSUtil﹕ Exception while resovling SRV records for myapp.ddns.net. Consider adding '_xmpp-(server|client)._tcp' DNS SRV Records

For android.os.NetworkOnMainThreadException, you need

if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);}

Also you can try to set host value

   configBuilder.setHost("myapp.ddns.net");
