Obtain GPS co-ordinates and save as a text file

Question

First of all I'm a complete noob to android, and any help that you may be able to give will probably need to be in the most basic language possible to use for me to understand.

Basically I need to extend a current application with some feature. The current application already has the ability to send a SMS to the phone with a codeword + password and it will identify the GPS co-ordinates of the phone.

What I'm looking to do is have these GPS co-ordinates saved on a textfile viewable to the user sending the text. Unfortunately I have no idea what the code for this would look like. I've attempted to search the web and I was unable to find anything I had the ability to implement.

Thanks to anyone who is able to provide some assistance.

code:

locationManagerNetwork = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    Location location2 = locationManagerNetwork
                    .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

if (location2 != null) {       
                String message = String
                        .format("Yout location : \n Longitude: %1$s \n Latitude: %2$s",
                                location2.getLongitude(), location2.getLatitude());
                Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG)
                        .show();

   //use here file writer if you want to write the coordinastes in a text file
            }

for writing sd card

File sdcard = Environment.getExternalStorageDirectory();
        File f = new File(sdcard, "/yourfile");

if(!f.exsist()){
f.createNewFile();
//Use outwriter here, outputstream search how to write into a tet file in java code 
}

you can also use this code

@Override
public void onLocationChanged(Location location) {
    // TODO Auto-generated method stub
    if (location != null) {
        long time= System.currentTimeMillis();
        String millisec = "" + time;
        double lat = location.getLatitude();
        double longe = location.getLongitude();
        loc = millisec + "\t" + lat + "\t" + longe + "\n"; 
        try {
            FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_APPEND);
            fos.write(loc.getBytes());
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}
