Thanks Lew. I have figured it out (after reading the API docs ++.)
So here is the code I use to transform the Lat long to UTM ( in case anyone
else wouders..)
[code]
public void convert (){
double a = 6378137;
double b = 6356752.3142;
e = Math.sqrt(1-Math.pow(b,2)/Math.pow(a, 2)); // a and b
are constants.
e2 = e*e/(1-(e*e));
n =(a-b)/(a+b);
A0 = a*(1 - n + (5/4)*(Math.pow(n,2) - Math.pow(n,3)) +
(81/64)*(Math.pow(n,4) - Math.pow(n,5)));
B0 =(3*a*n/2)*(1 - n - (7*n*n/8)*(1-n) + (55/64)*(Math.pow(n,
4)-Math.pow(n, 5)));
C0 =(15*a*n*n/16)*(1 - n +(3*n*n/4)*(1-n));
D0 =(35*a*Math.pow(n, 3)/48)*(1 - n + 11*n*n/16);
E0 =(315*a*Math.pow(n,4)/51)*(1-n);
zone = (int) (31 + (lngdeg/6));
double pi = 6* zone -183;
double pii = (lngdeg-pi)*Math.PI/180;
double rho1 = (1-(e*e) * (Math.sin(lat)*( Math.sin(lat))));
rho = a * (1-e*e)/ Math.pow(rho1, (3/2));
nu = a/(Math.pow((1-(e*e *(Math.sin(lat))*(Math.sin(lat)))), (1/2)));
S = A0* lat - B0 * Math.sin(2*lat) + C0 * Math.sin(4*lat) - D0 *
Math.sin(6*lat) + E0 * Math.sin(8*lat);
double Ki = S * knu;
double Kii = knu * nu *Math.sin(lat)*Math.cos(lat)/2;
double Kiii = (knu * nu
*Math.sin(lat)*Math.pow(Math.cos(lat),3)/24)*(5-Math.pow(Math.tan(lat),2)+9*Math.pow(e2,2)*Math.pow(Math.cos(lat),2)+4*Math.pow(e2
,2)*Math.pow(Math.cos(lat),4));
double Kiv = knu * nu *Math.cos(lat);
double Kv = knu *
Math.pow(Math.cos(lat),3)*(nu/6)*(1-Math.pow(Math.tan(lat),2)+e2*Math.pow(Math.cos(lat),2));
double UTMni = (Ki+Kii*Math.pow(pii, 2)+ Kiii * Math.pow(pii,4));
double UTMei = 500000 + (Kiv*pii + Kv * Math.pow(pii, 3));
UTMn = (int) UTMni;
UTMe = (int) UTMei;
}
