I've just now tried to get an android activity to run, however when
executing the application ("hello world", really) I get the following
error:

------------------------------------------------------------------------------------
It seems clojure depends on java.beans.Introspector.getBeanInfo, which
is not part of the android java API. Anyone else experience this
problem (running on clojure-1.2.0-master)?
The app which causes this:
------------------------------------------------------------------------------------
(ns tk.clojure.core
(:gen-class
:extends android.app.Activity
:exposes-methods {onCreate superOnCreate}))
(defn -onCreate [this #^android.os.Bundle bundle]
(.superOnCreate this bundle)
(let [tv (android.widget.TextView. this)]
(.setText tv "Hello World")
(.setContentView this tv)))
