I am new to this API (Watson API) and my Android experience is kind a rusty so please bear with me if I cannot catch up with your terminologies/ideas right away.
According to Watson API guide (you can check it in here https://github.com/watson-developer-cloud/java-sdk)
"Once you have credentials, copy config.properties.example to src/test/resources/config.properties, and fill them in as necessary."
Currently I am stuck in this area. Where can I find that config file?
