I am trying to follow this tutorial on lein-droid-based Clojure development on Android. However, the tutorial skips on setting up Cider support.

I start with a default lein-droid project by adding 

:user {:plugins [ [lein-droid "0.4.0-alpha4"] ]}

to my ~/.lein/profiles.clj, and then run

$ lein droid new android-hello com.example.android_hello

According to the tutorial, I should be able to do a lein droid doall and then connect with Cider to localhost:9999 at this point; however, it is unusable because of nREPL missing on the Android side:

; CIDER 0.9.1 (Java 0, Clojure 1.7.0-beta3-r2, nREPL nil)
WARNING: CIDER's version (0.9.1) does not match cider-nrepl's version (not installed)

So then, according to this other tutorial that I've found, I should add cider-nrepl to my Android dependencies by adding this to ~/.lein/profiles.clj:

:android-user {:plugins [[cider/cider-nrepl "0.9.1"]]
                :android {:aot-exclude-ns ["cider.nrepl.middleware.util.java.parser"
                                           "cider.nrepl" "cider-nrepl.plugin"]}}}

So I do a new lein clean; lein droid doall to make sure everything is picked up nicely; and now the resulting program crashes on Android at startup:

Seems you made a small mistake when following the tutorial you referenced above.

This:

:android-user {:plugins [[cider/cider-nrepl "0.9.1"]]
                :android {:aot-exclude-ns ["cider.nrepl.middleware.util.java.parser"
                                           "cider.nrepl" "cider-nrepl.plugin"]}}}

Should be:

:android-user {:dependencies [[cider/cider-nrepl "0.9.1"]]
               :android {:aot-exclude-ns ["cider.nrepl.middleware.util.java.parser"
                                          "cider.nrepl" "cider-nrepl.plugin"]}}
