Follow the Android integration guide and the feature definition reference. Example implementation here.
Nimbus FML: https://experimenter.info/technical-reference/fml/fml-spec
There are some clarification on how to test your Nimbus implementation:
After building Fenix, make sure you turn on
Secret Settings->Use Nimbus Preview Collections.The experiment in https://stage.experimenter.nonprod.webservices.mozgcp.net/nimbus/ does not have to be live for the test. In preview is sufficient.
Example of a test is here.
Make sure you archive the test after you’re done with it.
In your PR, make sure to submit the change for .experimenter.yaml as well.
