I try to implement Uber in my Android application and created an app in Uber with following scope **(Access to your full name, email, photo and promo code. & Access to some of your Uber activity. This includes times, distances traveled and Uber products used. ) ** and my redirect url is http://localhost/auth I have given client id & server token in manifest file. Please help me on resolve this issue. where did I made mistake on the app? Do I need to enable other scope?.

This is failure response: https://login.uber.com/oauth/token?client_secret=xxxxxxxxxx&client_id=xxxxxxxxxxxx&grant_type=authorization_code&code=xxxxxxxxxx&redirect_uri=http%3A%2F%2Flocalhost%2Fauth
