ServiceBusException while connecting from Android application #402

asbapat commented 4 years ago

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} at com.microsoft.azure.servicebus.primitives.ExceptionUtil.toException(ExceptionUtil.java:74) at com.microsoft.azure.servicebus.primitives.MessagingFactory.onConnectionError(MessagingFactory.java:414) at com.microsoft.azure.servicebus.amqp.ConnectionHandler.onTransportError(ConnectionHandler.java:170) at org.apache.qpid.proton.engine.BaseHandler.handle(BaseHandler.java:191) at org.apache.qpid.proton.engine.impl.EventImpl.dispatch(EventImpl.java:108) at org.apache.qpid.proton.reactor.impl.ReactorImpl.dispatch(ReactorImpl.java:324) at org.apache.qpid.proton.reactor.impl.ReactorImpl.process(ReactorImpl.java:291) at com.microsoft.azure.servicebus.primitives.MessagingFactory$RunReactor.run(MessagingFactory.java:556) at java.lang.Thread.run(Thread.java:764)

Can you please what the exception is and why is it being thrown. Thank you..!!!

@asbapat just a couple of thoughts to eliminate the SAS token as the issue. Can you try the same token with our C# SDK - we have many samples or use the RootManageSharedAccessKey?

What is the connection string you are using? It looks like a failure to establish connection to service bus. Either 1. The connection string is wrong. Or 2. Something with the environment or network or firewall.

Ultimately, this solution (SB SDK on Android) is not the most elegant way of getting notifications on the device. Have you considered the following options?

Logic Apps > Service Bus Connector > Email via O365 connector Logic Apps > Service Bus Connector > SMS Text Logic Apps > Service Bus Connector > Azure Function w/ Notification Hub bindings for Push Notification

These are all more elegant & use built-in capabilities on the devices.

I have the same error message but it’s a java app running on azure container instance. I’ve tried using the same connection string with a dot net version of the app also running in ACI and it works just fine. The same java app runs fine locally and also on a normal azure VM.

I can’t figure this out - the logs don’t contain any hints as to what the problem is.

I have connected to the aci container running the java app and tried to telnet to service bus on the AMQP ports with no problems. It’s not a connectivity issue.
