Android : Android Google Maps V2 - On Camera moving Event

I think my question is already obvious - I wish for a listener everytime the map Camera is changing.

I already had on Touch event, on Dragged Event. However, I cannot catch the event when the map is moving (example, I strongly swipe the Google maps and the map is moving co-related to the force I exerted without my finger on the screen anymore. )

Please help.. Thank you very much!
