Solution:
Android is really the worst when it comes to anything that is not DRM: IT HAD 'MURRICAN KEYBOARD LAYOUT! OF COURSE! Yes, I know Google knows better than accepting what the user wants to do or configure, but that even beats windows in malevolency.
I cannot fathom the nightmares emteria had when porting that ****hole of an operating system to the RPi. So kudos to you and thanks for the trial possibility.
It might have helped to let the error message be "wrong username or password" instead of "Error contacting server".
