ServiceBusException while connecting from Android application

I am trying to subscribe to azure service bus from android application using Topic based subscription and SASAuthorizationToken. However I am getting the following exception:

` W/System.err: com.microsoft.azure.servicebus.primitives.ServiceBusException: Error{condition=proton:io, description='null', info=null}
