Likely the OAuth is not yet supported in the Native client. May I know if you've time to contribute a fix by copying the template from other clients (http libraries) ?

jersey2 should have pretty good Oauth support (e.g. automatic token refresh, etc)

thanks @wing328 i think i was thrown off as the readme doc generated for native in the example had OAuth. So was not sure if it was supported or not.

The default which is okhttp supports oauth and looks good setting access token. I havent looked into the impl yet around refresh and how that works. is there an example in the repo of RetryingOAuth?

Realistically, im a bit swamped with meetings at the moment so cant commit anytime. I might see if my team has capacity to investigate.

      // google-api-client doesn't use the OpenAPI auth, because it uses Google Credential directly (HttpRequestInitializer)
            if (!(GOOGLE_API_CLIENT.equals(getLibrary()) || REST_ASSURED.equals(getLibrary()) || usePlayWS
                    || NATIVE.equals(getLibrary()) || MICROPROFILE.equals(getLibrary()))) {
                supportingFiles.add(new SupportingFile("auth/OAuth.mustache", authFolder, "OAuth.java"));
                supportingFiles.add(new SupportingFile("auth/OAuthFlow.mustache", authFolder, "OAuthFlow.java"));
            }

Im guessing these are the libs that do not support oauth right now?

Configuration.setDefaultApiClient(new ApiClient(clientId, clientSecret, parameters));

i believe this then incorporates the retry mechanism. Will test it out.
