This is really easy if you use your own server. Simply store lat/long values for the points you'd like. To get points near another point construct a lat/long perimeter around it. Basically, like a rectangle you'll have a start x,y lat/long pair and an end lat/long pair. You can then query your database to pull points within that perimeter.
I suck at math so I used: http://search.cpan.org/~asp/Geo-Calc-0.04/lib/Geo/Calc.pm Some APIs may offer something like this. FYI, as other have pointed out. This has little to nothing to do with Android. Everyone has given you good tips, but come back with Android specific questions plz.
