String searchPattern = "123 Main St."
    LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    //I use last known location, but here we can get real location
    Location lastKnownLocation = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);

    List<Address> addresses = null;
    try {
        //trying to get all possible addresses by search pattern
        addresses = (new Geocoder(this)).getFromLocationName(searchPattern, Integer.MAX_VALUE);
    } catch (IOException e) {
    }
    if (addresses == null || lastKnownLocation == null) {
        // location service unavailable or incorrect address
        return;
    }

    Address closest = null;
    float closestDistance = Float.MAX_VALUE;
    // look for address, closest to our location
    for (Address adr : addresses) {
        if (closest == null) {
            closest = adr;
        } else {
            float[] result = new float[1];
            Location.distanceBetween(lastKnownLocation.getLatitude(), lastKnownLocation.getLongitude(), adr.getLatitude(), adr.getLongitude(), result);
            float distance = result[0];
            if (distance < closestDistance) {
                closest = adr;
                closestDistance = distance;
            }
        }
    }
    return closest; //here can be null if we did not find any addresses by search
