How to add favorites objects on Google map for android

Guess I'm still a little confused as to what you are trying to do.

Any contact that also has an address will show up when you open "Navigation" then contacts.

Check out the onTap method for the overlay class: http://code.google.com/android/add-ons/google-apis/reference/index.html

When someone taps the overlay it will call the onTap method, with GeoPoint P having the point that has been tapped. This won't display all the information that the google maps app displays from a favorites, though. I don't think that information is part of the google maps API, but rather is proprietary to google maps app. I could be wrong. You can display your own information about a favorites, when it's tapped with the onTap method though.

EDIT: Of course you could do most of the same stuff the google maps app does. From the GeoPoint information you could display the address when it is tapped. Put a :"Driver To" link on the map for them to click on, and then call the navigation app with an Intent, specifying the address in the parameters.

2nd EDIT: I wrote a small gps program once, here is the code I used to translate a lat/lon location to an address:

First you would get the lat and longitude from the GeoPoint provided in the onTap method of your overlay:

int lat = p.getLattitudeE6();
int long = p.getLongitudeE6();

Then create a Geocoder object:

Geocoder geoCoder = new Geocoder (getApplicationContext());


address="Could Not determine location."; //initinalize the address to not found

try {

//Use android.location.Location to get an address from a geoCoder object.

android.location.Location locs = geoCoder.getFromLocation (lat, long, 10); // get the address for the lat and long from the GeoPoint

if (locs.get(0) !=null) address=locs.get(0).toString(); //get the string representation of the address from locs
} catch (Exception e) {
//System.out.println ("location: "+e);
}

Your probably right, but I wasn't able to find it looking through the maps api reference. I'll look again and let you know if I find anything.

Marko, have you tried contacting the developers of the apps that had the ability you want? As long as you aren't making a competing product, they might be able to help you.
