It really depends what you want from your Haskell on Android. If you want to write Haskell98 code on Android, you can use JHC and create NDK bindings yourself. If you want to be able to use cool packages from Hackage and the features of a high performance runtime like GHC. You are talking about a tremendous level of effort requiring corporate or academic sponsors. It seems like the inevitable conclusion of functional programmers on Android is to invest your time in Clojure and Scala. Maybe in the next few years, an investment bank will sponsor a high performance ARM runtime for Haskell. - Zaki Manian
