 ello everyone,

As the title suggest i have (sometimes) a
concurrentmodificationexception while trying to create a route between
two locations ...
Here is my code (and in case you're wondering MyOverlay does not try
to access the other Overlays in the map)

private class fillRouteTask extends AsyncTask<Void, GeoPoint,
Void> {

* create the url to call to get the route
* @param src
* @param dest
* @return
private StringBuilder createUrl(GeoPoint src, GeoPoint dest) {
// connect to map web service
StringBuilder urlString = new StringBuilder();

urlString.append("&saddr=");// from
.toString((double) src.getLatitudeE6()
/ 1.0E6));
.toString((double) src.getLongitudeE6()
/ 1.0E6));
urlString.append("&daddr=");// to
.toString((double) dest.getLatitudeE6()
/ 1.0E6));
dest.getLongitudeE6() / 1.0E6));
Log.d("xxx", "URL=" + urlString.toString());

return urlString;

* create the connection to google url
* @param src
* @param dest
* @return
private String connectToUrl(GeoPoint src, GeoPoint dest) {

// get the kml (XML) doc. And parse it to get the
// coordinates(direction
// route).
Document doc = null;
HttpURLConnection urlConnection = null;
URL url = null;
try {
url = new URL(createUrl(src, dest).toString());
urlConnection = (HttpURLConnection)

DocumentBuilderFactory dbf =
DocumentBuilder db = dbf.newDocumentBuilder();
doc = db.parse(urlConnection.getInputStream());

(doc.getElementsByTagName("GeometryCollection") != null

1. Android API


I think the Android developers must spend a few hours in making the
Android API more productive.
There are several points where the developers stucks in the API for
example the ArrayAdapter. Normally you have a display value for
displaying a list or Spinner  and some id-value you want to use
internally (this could be the record _id in the SQLite DB).
I found no possibility to provide a second id-value for the
ArrayAdaper for the Spinner that could be retrieved after the user has
select an item (spinner.setOnItemSelectedListener), Instead of an
meaningfull id-value, I get a sequential  index-value that is not very
