Hi, I have gone through Larry's code . I found that he is not authenticating the user's credentials . He picks it from "setting shared preference". Whether user set the user's Player credentials in "setting shared preference" or not , he is unable to know why he can't run this workflow if user's credentials are wrong or not set or incorrect input ?
I have asked it because Retrofit with RxJava take all 4xx status code as an error. Now as @stain says I have to handle it in android app side . So,I am working on it. Thanks Sagar
