How to set hessian threshold value for surf detectror in opencv library.

In C++. I can set it as:

int minHessian = 100;
SurfFeatureDetector detector( minHessian );**

But in android, surf detector is created as:

FeatureDetector surf=FeatureDetector.create(FeatureDetector.SURF);

So, how does I set the value of min hessian in android.

Make note that, SURF is not available in newer versions of opencv library, I am using opencv 2.4.1, so that I can do surf detection in android.

"Make note that, SURF is not available in newer versions" - are you sure ? seems i can create SURF/SIFT on android 2.4.6 and on desktop 3.0.

SURF didn't dissappear, it just moved to the nonfree module. Probably that got you confused. It falls out of the scope of the OpenCV BSD license.
