Problems while trying to see the route between two locations using Google Maps

I'm using a background thread to read from a Sqlite database some GPS data...and I store it in some GeoPoints.....After I finish reading the data I wanna use an intent in order to see the route described by that data.

Here is my code:

protected List<GeoPoint> doInBackground(DBAdapter... db) {
    try {
        db[0].openDataBase();
        Cursor c = db[0].getAllData();

        if (c.moveToFirst()) {
            do {
                longitude = Integer.parseInt(c.getString(0));
                latitude = Integer.parseInt(c.getString(1));
                p = new GeoPoint(latitude, longitude);
                geoPointsArray.add(p);
            } while (c.moveToNext());
        }
        c.close();
        db[0].close();
    } catch (Exception e) {
        Log.d("Eroare", "doInBackground", e);
    }
    return geoPointsArray;
}

protected void onPostExecute(List<GeoPoint> geoPointsArray) {
    int i = geoPointsArray.size();
    srcPlace = geoPointsArray.get(1);
    destPlace = geoPointsArray.get(i);
    Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
            Uri.parse(" http://maps.google.com?t=k&saddr=" + srcPlace
                    + "&daddr=" + destPlace));
    startActivity(intent);
}

But something, somewhere goes terribly wrong and I get the next output of the logcat:

Don't forget I wanna see the path on the map between those two points...so if u have suggestions about the URL are more than welcomed!

UPDATE:This is my second FC

The array index is based on zero. If i is your size, you need to call destPlace = geoPointsArray.get(i - 1);. And the source should be 0 and not 1.

protected void onPostExecute(List<GeoPoint> geoPointsArray) {
    int i = geoPointsArray.size();
    srcPlace = geoPointsArray.get(0);
    destPlace = geoPointsArray.get(i - 1);
    Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
            Uri.parse(" http://maps.google.com?t=k&saddr=" + srcPlace
                    + "&daddr=" + destPlace));
    startActivity(intent);
}

Your error is in

int i = geoPointsArray.size();
        srcPlace = geoPointsArray.get(1);
        destPlace = geoPointsArray.get(i);

needs to be destPlace = geoPointsArray.get(i-1);
