After a user has already logged into the app, I have their username and password saved to shared preferences, therefore when they login again, they should be able to authenticate automatically and subsequently bypass the login activity.
I have started and binded the service, and sent the authenticate methods to the server, yet the section:
result = imService.authenticateUser(
userName.trim(),
password.trim());
always returns NULL and does not allow automatic logging in.
Why would this be the case?
