Get the location address of the wrt polygon I'm in

I have over 200 polygons to create, and I get this location by LocationListenerOnChanged (), but I would like to know which of the polygons I am based on the current location.

How can I use LatLng to check inside each polygon every 2 miles. And how can I make the whole process faster or will the android os function be built in.

I checked a lot of documents related to Android v2 cards, but I did not get any information about this. I appreciate any wrt help on the topic. Thanks in advance.
