[android-developers] Decreasing double tap timeout in GestureDetector

Hi,
This is for an application listening to both single and double tap events.
Android's GestureDetector has a 300 ms [1] timeout to distinguish betweens single and double taps. If the second tap has not occurred for 300ms, onSingleTapConfirmed is called [2].

Whats the best way to reduce this timeout to something lesser, say 200ms?

I looked at the code and found that GestureDetector posts and empty message to be delivered after 300ms. And onSingleTapConfirmed() is called when that message is delivered to GestureDetector's handler.
Would I be able to post the same message but with a lesser delay from my gesture detector's onTouchEvent method?

Thanks.
