getting this exception in java ticker , how can i fix this

sujith · February 2018

Are you sending a valid api_key and access_token?
Can you give more details about how and when it happens?

ayyaz · February 2018

where to catch connection refused exception consider i lost internet connectivity , since you are providing call backs and there is no way for programmer to catch exception , like onconnection doesnt make sense

sujith · February 2018

You can use onErrorListener to listen to errors.

ayyaz · February 2018

please point to an example

sujith · February 2018

You can set it like setting any other listener as mentioned here.

ayyaz · February 2018

already done , but connection refused is not handled , i dont find any call back for onErrorListener in your link

sujith · February 2018

Is this crashing the app?
We will add the callback to the examples. But ideally, all the errors are handled and sent to the user via onErrorListener.
Can you give complete stack trace, so that we can see where is it thrown from our code?

you can see in stack trace connection got disconnected , tcp detected , due to this reconnect was attempted but since there was no net connectivity connection got refused resulted in application crash if u can quickly paste the solution clearly which i can add right away , please dont point anywhere which leads to confusion ...

if u can quickly paste the solution clearly which i can add right away , please dont point anywhere which leads to confusion ...

I'm afraid that's not how it works, @ayyaz. We cannot give you ready-made code that you can copy paste and will magically solve all your problems. There are enough examples on the clients to get you started and we have a comprehensive documentation. You can also look at the source code of the client libraries, which themselves are straight forward.

ayyaz · February 2018

I am not expecting that my question is straight please provide me solution asap rather than unrelated discussion
Please let me know how can I catch network exceptions like connection refused or not reachable

Also recently this exception received please suggest on that too

sujith · February 2018

You need to listen to errors by implementing the onErrorListener and handle there.
You can check out updated examples in javakiteconnect repository.

ayyaz · February 2018

OK how I reconnect if connection refused
Or if websocket error what is correction method in error listener
