I want to try and test different detectors and extractors available for OpenCV. In the process, I learned about SURF & SIFT and also found that they are now patented and kept in nonfree module.

Now I want to give a try to those modules and hence I built source(opencv) manually; But I got result files as *.dylib(http://snag.gy/3SHeT.jpg) Now how can I use(link/load/include) these files in Android C/C++'s code? Please correct me, if I'm assuming or doing something wrong.

I've googled enough about this, but couldn't found any relevant link, explaining this process throughly..so please help.

It would be awesome, if you can also help me to know which files one should include to use GFTT_DETECTOR, HARRIS_DETECTOR, SIMPLEBLOB_DETECTOR, HARRIS_DETECTOR, GRID_DETECTOR and other if any.

You build OpenCV for your host Mac OSX system. You need to install Android SDK, Android NDK, Apache Ant and build OpenCV with special android toolchain in android folder of source code. There are some basic build scripts for android in android/scripts. You can use it as reference.
