After batteling the ever-great, mighty overlord of hell Lucifer Morningstar himself for over 666 minutes I finally managed to compile dbclient+dropbearkey for API level 21 and above. ( Lollipop+ ) It only supports public key authentication because getpass() wouldn't work on Android _yet_ . Boy Android NDK really is a mess. ( Either that or I'm stupid. )
Here's the git repo.
Most of my knights have already fallen in battle and it's almost sunrise. So I don't have the strength, time or courage to finish the job and do sshd ( dropbear ) too. Maybe another time when my armies are back on their feet.
