I'm trying to implement a demo [1] with AeroGear OTP and I am having some problems to login. When HttpURLConnection tries to call getAuthorizationCredentials this[2] exception is thrown.

PS1: Doing the same requests[3] using curl I see no problem.

PS2: I changed the aerogear-android library on this branch[4] because the controller is expecting demo-id instead of username
