How to add a custom keyboard layout? Disclaimer: There seem to be a number of potential duplicates to this question on common android forums and SX sites (e.g.: How to install a custom keyboard in Android?), but many are a couple of years old and none seem to be what I'm hoping for. Thence:

Looking for a solution that


does not require rooting
does not require additional apps, ideally
does not require "serious" coding


Any ideas?

Closest working solution I was able to get was to use JBak Keyboard which allows you to customise it's layout and skins using simple XML files.
