I am working in odoo mobile application development.

I use XML-RPC Web-service from this document 

https://www.odoo.com/documentation/8.0/api_integration.html

My sample xml-rpc connection code

XMLRPCClient client = new XMLRPCClient("http://test.xxxxxxx.in/xmlrpc/2/object");
response =  client.call("execute_kw",Constant.db_name,user,password,
 "product.product","get_root_category", Collections.emptyList());

I want cancel this xml-rpc connection at run-time?

Any body help me. Thanks
