        AuthorizationFlow.Builder builder = new AuthorizationFlow.Builder(
                BearerToken.authorizationHeaderAccessMethod(),
                AndroidHttp.newCompatibleTransport(),
                new JacksonFactory(),
                new GenericUrl("https://login.uber.com/oauth/token"),
                new ClientParametersAuthentication("ADQjXcw8g7IG2d_wS2Yb0k0KA9YwKvYS",
                        "7R3GUDd-wW4Obtis9fKNkhvYL6t9Mz9hb3Z5Je5w"),

                "https://login.uber.com/oauth/authorize");
        builder.setCredentialStore(credentialStore);
        ArrayList<String> scopes = new ArrayList<>();
        scopes.add("profile");
        scopes.add("places");
        //   scopes.add("request");
        builder.setScopes(scopes);
        AuthorizationFlow flow = builder.build();

        AuthorizationUIController controller =
                new DialogFragmentController(getFragmentManager()) {


                    @Override
                    public String getRedirectUri() throws IOException {
                        return "https://grabbngo";
                    }

                    @Override
                    public boolean isJavascriptEnabledForWebView() {
                        return false;
                    }

                    @Override
                    public boolean disableWebViewCache() {
                        return false;
                    }

                    @Override
                    public boolean removePreviousCookie() {
                        return false;
                    }
                };

        OAuthManager oauth = new OAuthManager(flow, controller);

        OAuthManager.OAuthCallback<Credential> callback = new OAuthManager.OAuthCallback<Credential>() {
            @Override
            public void run(OAuthManager.OAuthFuture<Credential> future) {
                try {
                    Credential credential = future.getResult();

                    //credential.getRefreshToken();

                    getUberStuff(credential.getAccessToken());
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        };
        oauth.authorizeImplicitly("userId", callback, new Handler());
    }

void getUberStuff(final String token) throws AuthFailureError {
StringRequest stringRequest = new StringRequest(Request.Method.GET, "https://api.uber.com/v1/me",
new Response.Listener() {
@OverRide

        }
    }) {
        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {

            Map<String, String> params = new HashMap<>();
            params.put("Authorization", "bearer " + token);
            return params;
        }
    };
