Hello ,
I'm getting a blue screen for the following code.. could i get some help on this.see my attachments for the screen shot...... thanks.. thanks

public class Mapping extends MapActivity

adress = (EditText) findViewById(R.id.simpleGM_adress); // Get address from XML
gc = new Geocoder(this); // create new geocoder instance

btnSearch.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
String addressInput = adress.getText().toString(); // Get input text
//onclick goes here...

try {

List<Address> foundAdresses = gc.getFromLocationName(addressInput, 5); // Search addresses
if (foundAdresses.size() == 0) { // if no address found,
// display an error
/*Dialog locationError = new AlertDialog.Builder(
Mapping.this).setIcon(0).setTitle(
"Error").setPositiveButton(R.string.ok, null)
.setMessage(
"Sorry, your address doesn't exist.")
.create();
locationError.show();*/
} else { // else display address on map
for (int i = 0; i < foundAdresses.size(); ++i) {
// Save results as Longitude and Latitude
// @todo: if more than one result, then show a
// select-list
Address x = foundAdresses.get(i);
lat = x.getLatitude();
lon = x.getLongitude();
//

Are you sure it's not just plotting you in the middle of a lake or ocean all the way zoomed in? Can you zoom out and see the area around it?

I'm not able to access the zoom controls of it after i click on the go button... i'd uploaded the whole zip of my project...could you please run it and chek...thanks for your reply.

Yes you were right, it is plotting into sea....could i get suggestions to remove that?

lat=lat*1000000; lon=lon*1000000;


I've placed the following code after lat = x.getLatitude();
lon = x.getLongitude();

this code...i'm able to acheive the plotting .... thank you very much for you reply...i came to know wher i have done hte mistake. keep helping the community like you are doing.. thanks..

Haha I wish I could've helped more.

Also, you can achieve zooming and moving the map by using the MapController.

MapController mc = theMap.getController();

Hi men, I got a question, may yo explain me this part, I got error when i do this



First do you must create an instance of the Mapping class in the MapOverlay class??
Cause if I put

I got a mistake
