Answer 1

You want to perform an operation of geocoding.

Use the method Geocoder.getFromLocationName(String locationName, int maxResults).

It will return a list of objects Address, which in turn have the methods Address.getLatitude() and Address.getLongitude().

Example

(Untested, it should actually be modified to bring the data into one thread apart, because it is too heavy for the thread home of Android):

Geocoder geocoder = new Geocoder(this);
List<Address> enderecos = geocoder.getFromLocationName("Av. Sampaio Vidal, Centro, Marília, SP", 1);
if (enderecos.size() > 0) {
    Log.v("tag", "coordenadas " + enderecos.get(0).getLatitude() + ", " + enderecos.get(0).getLongitude());
}

Answer 2

This probably won’t be the answer but it’s just to try to give a light: I get the coordinates by extracting them from a query as follows:

URL PERMANENTE: http://maps.googleapis.com/maps/api/geocode/json?address=

ENDEREÇO: Av. Sampaio Vidal,Centro, Marília, SP

Concatenates the url with the address and will have tudo on the query performed within a array, then simply extract the data you want.

Exemplo: http://maps.googleapis.com/maps/api/geocode/json?address=Av. Sampaio Vidal,Centro, Marília, SP
