It is true that Android (and iPhone) asks you these questions when you
click on an 802.1x EAP network. Unfortunately they have to ask the use
up front before proceeding with the connection attempt, since the WiFi
network information from the Access Point does not contain any
information about the used EAP protocol. Thus they are as lost as
ConnMan what the EAP method of connecting to the network actually is.
Asking the user happens before anything starts connecting.

Whether any certificates exist or not needs a user decision as much as
the EAP method itself. Thus any UI trying to connect to an 802.1x EAP
network must prompt the user, give the information to ConnMan and then
connect. The current implementation in ConnMan is such that an EAP
network needs to be described as a .config file. Maybe it's less
implementation friendly to write a file with the needed information, but
it shouldn't be a too big obstacle since the UI has already received all
the needed (known) information from the user.
