[Question] Android: My own providers are not supported yet?

I’ve implemented iOS app for my own oauth provider with rn-oauth. It works as I expected.

But on Android, it doesn’t. I got following error on OAuthManager#authorize().

04-09 22:22:55.143  5149  5189 E AndroidRuntime: Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String com.github.scribejava.core.oauth.OAuth20Service.getAuthorizationUrl()' on a null object reference

So I read some code, found this static method, and it seems additional providers are not cosidered on Android.

  static public OAuth20Service getApiFor20Provider(
    final String providerName,
    final HashMap params,
    @Nullable final ReadableMap opts,
    final String callbackUrl
  ) {
    if (providerName.equalsIgnoreCase("facebook")) {
      return OAuthManagerProviders.facebookService(params, opts, callbackUrl);
    } else if (providerName.equalsIgnoreCase("google")) {
      return OAuthManagerProviders.googleService(params, opts, callbackUrl);
    } else if (providerName.equalsIgnoreCase("github")) {
      return OAuthManagerProviders.githubService(params, opts, callbackUrl);
    } else if (providerName.equalsIgnoreCase("slack")) {
      return OAuthManagerProviders.slackService(params, opts, callbackUrl);
    } else {
      return null;
    }
  }

Not supported yet on Android ? Or there is the way to get my own provider work?

Thank you vbuch, your code almost works! I’ll continue to try detailed test.

The problem is solved in accessTokenResponse of OAuthManagerModule.java:

      String callbackUrl = (String) cfg.get("callback_url");

      if (callbackUrl == null) {
        callbackUrl = "http://localhost/" + providerName;
      }
