Java compiler for android phones

Question

I have done a little googling but not found too much info on the subject so im asking here,

Does any body know of a phone based java or c/c++ compiler so a dev could effectively use his phone to do some preliminary dev work (or just to play around with when bored on the tube :))

Answer 1

I just found terminal-ide ( https://market.android.com/details?id=com.spartacusrex.spartacuside&hl=en), and it is awesome if you are not afraid of the command line. Onboard java compiler.
