I am getting a rare but consistent error reported by a few users of my Android app. The user feedback is consistent with this web page that reports the error whenever a user of Android Gingerbread 2.3.1 touches the screen in the Tricorder program:

http://code.google.com/p/moonblink/issues/detail?id=138

I call event.recycle() in the onTouchEvent method, but I am not returning false afterwards. So this answer does not apply:

Why would onTouch() generate FATAL EXCEPTION when returning false?

Is this a bug in Gingerbread? I have never heard of this happening to my apps in 2.1 or 2.2.

The entire stack trace as reported by the Google Developer Console is:

java.lang.RuntimeException: MotionEvent{40521420 action=0 x=368.0 y=373.04865 pressure=0.3921569 size=0.0} recycled twice!

Maybe you could remove event.recycle() from you onTouchEvent() method because it seems that the system has already done that for you. I got the same exception and everything is OK after I remove event.recycle().
