How to return a radius/key-word search of my data using Google Maps Android API v2

Question

I am building a Android app using the Google Maps Android API v2.

I have a database of lat/long that Im trying to search and display, either by radius(in miles) and/or key-word based on my current location.

What would be the best way to approach this problem?

Thank you in advance.

what do you want to search and display ? Places associated with these lat/lngs ? — ddewaele, May 28 '13 at 06:38

How I would approach it:

Get the users location in lat/long
User the haversine formula to compute the distance to points already in your database.
Filter out the points that meet your threshold criterea (less than 5 miles for example)
Within the GoogleMaps class, look at the addMarker() method. Use this to add your filtered database lat/long to the map.

A similar approach with keywords, you filter by keyword and not haversine distance.
