Re: No non-anonymous SASL authentication mechanism available in android

My bad I was not calling XMPPTCPConnection.connect() before login.

Looks like there a few bugs in login methods

1. XMPPTCPConnection.login(userName, passWord) method does not throw a NotConnectedException even though  XMPPTCPConnection.connect() was not called. It throws the exception mentioned in the original question.

2. XMPPTCPConnection.login() when called before calling XMPPTCPConnection.connect() throws the following inappropriate exception

java.lang.RuntimeException: Unable to create service sample.app.service.MessageService: java.lang.NullPointerException: Attempt to invoke virtual method 'void org.jivesoftware.smack.tcp.XMPPTCPConnection$PacketWriter.throwNotConnectedExce ptionIfDoneAndResumptionNotPossible()' on a null object reference
