I tried out the Android client. I could not get the keyboard up in console mode. There is always some trick to things in the Android client, it seems. That sort of thing will just piss off and drive away potential new players. When will we get a keyboard summoning icon? For any device without a working physical keyboard, that would be very helpful.

This really old article says that it should be really easy to just pull up a virtual keyboard in SDL.
