It's not possible to use java constants in a case statement. condp = could be used in this case but these are things which could be used in a java switch statement and so it's annoying to give up constant time dispatch. For example:
(case (.getActionMasked event)MotionEvent/ACTION_POINTER_DOWN :downMotionEvent/ACTION_UP :upMotionEvent/ACTION_POINTER_UP :upMotionEvent/ACTION_MOVE :moveMotionEvent/ACTION_CANCEL :cancelMotionEvent/ACTION_OUTSIDE :outside:none))
Doesn't work, but there is no reason this couldn't be resolved at compile time and dispatched in constant time.
Another solution for this problem: http://dev.clojure.org/jira/browse/CLJ-1368
