Hi Backendless Team,
Im tryin to integrate Facebook Login in my Android App, but every time i click the login button I get You are not logged in. Please log in and try again Error, It does not ask me to login,
I have added api.backendless.com to Facebook Login --> settings --> Valid OAuth redirect URIs in my facebook developer console, Im using Backendless version 4.0.0-beta3 and this is my LoginActivity code :
PS : The New documentation regarding the Facebook Login is not complete … check it at https://backendless.com/docs/android/users_facebook_login.html
