Ah.
That's more about computing the distance than a data type problem.
See:
http://developer.android.com/reference/android/location/Location.html
static void distanceBetween(double startLatitude, double
startLongitude, double endLatitude, double endLongitude, float[] results)
Computes the approximate distance in meters between two locations, and
optionally the initial and final bearings of the shortest path between
them.
or
float distanceTo(Location dest)
Returns the approximate distance in meters between this location and
the given location.

Hi Kostya,
The picture is clearer now after your explanation.
I have an application server generating Latitude and Longitude in XML
and I pullpurse it in my program to compare to current location.
So I need to convert the Lat and Lon to Long so I can do a distant to
current location calculation.
The Integer is a XML value in meter to indicate whether I am in the
specific range and is also a string value after the pullpurser.
What do I need to do in conversion so I do not have any round/
trancated value?
Many thanks,
CJ

"1.3001505" is not a valid Integer.
Either:
- fix (round, truncate, etc.) the value to be an Integer when you're
putting it into the array;
- use Real.parseFloat / Double.parseDouble / NumberFormat to parse a
floating-point value;
- use a strongly-typed array (ArrayList<float>, ArrayList<Integer> etc.)
instead of an array of strings to avoid conversions altogether.

Yes, I want to transfer the value of StringArray tmp2 in position 1
so I do this String tmp3 = tmp2.get(1)...

Use the debugger, Luke :)
Check the value of tmp3 just before you call Integer.parseInt.
I am assuming you actually added a value to tmp2, so when you call
get(1) there is something there.

Hi, please help me out.
== This is ok ==
String tmp1 = "123"
int seed = Integer.parseInt(tmp1);
== This is not ok ==
ArrayList<String> tmp2 = new ArrayList<String>();
String tmp3 = tmp2.get(1);
//Added some value to the ArrayList, Toast value of tmp3 and sees the
correct value
int seed = Integer.parseInt(tmp3);
// I get runtime error here, what is wrong?
Happy new year.
