Im trying to load a private feature layer using app login. I have my App ID and a generated token and I'm trying to feed that data to a credential object and load the feature layer. But when the layer get loaded it still askes for log in infomation even though I have them attacehd with the feature layer.
How can I load a feature layer providng my app login info so that it will not pop the login info dialog ? Please help 
Find below the code I tired.
function layerLoad()
{
require(["esri/request", "esri/layers/FeatureLayer", "esri/Credential"],
function(esriRequest, FeatureLayer, Credential) {
var layers = [];
var featureLayer;
var layerOptions;
var token = "L7yIuZW-h9ODkLRHOpnWpYlxHzHVIUdUgKQQKHqPLOVrNHMYi3clvlCTF6V5Xw64Xor-TUsUtrmfKXnQ5iomxO6_ltRRGFpq-UlO01C4XnIN6wSxjtHp15ciXeUIsEEA3cknZKsFKA1IrE_P28zmug..";
var privateLayerUrl = "http://services.arcgis.com/u1pyDfVudZJk1pG6/arcgis/rest/services/Private_Layer/FeatureServer";
var privateLayerWithToken = privateLayerUrl + "?token=" + token;
var layersRequest = esriRequest({
url: privateLayerWithToken,
content: { f: "json" },
//form:{ token: token },
handleAs: "json",
//callbackParamName: "callback"
});
var credentials = new Credential({
userId:"eR4g2n1Qv1U18Od4", // App ID

});
layersRequest.then(
function(response) {
layerOptions = {
outFields: ["*"],
mode: FeatureLayer.MODE_ONDEMAND,
id: 55,
//credential:credentials,
visible: true
};
featureLayer = new FeatureLayer("http://services.arcgis.com/u1pyDfVudZJk1pG6/arcgis/rest/services/Private_Layer/FeatureServer/0", layerOptions);
featureLayer.credential = credentials;
layers.push(featureLayer);
