Answer 1

You can use the Location class's static distanceBetween() method like so:

    float[] distance = new float[1];
    Location.distanceBetween(lat, lon, currentLat, currentLon, distance);
    // distance[0] is now the distance between these lat/lons in meters
    if (distance[0] < 2.0) {
        // your code...
    }

If you have two Location objects, another option is distanceTo()
