Question

My application using a GeoCoder keeps returning the string to true. here is the code I have.

public boolean address(){
      Geocoder geoCoder = 
            new Geocoder
            (getBaseContext(), Locale.getDefault());

            try {
                List<Address> addresses = geoCoder.getFromLocation(LocationManagerHelper.getLatitude()/1E6, LocationManagerHelper.getLongitude()/1E6, 1);

                String addes = "";
                if (addresses.size() > 0) 
                {
                    for (int i=0; i<addresses.get(0).getMaxAddressLineIndex(); 
                         i++)
                       addes += addresses.get(0).getAddressLine(i) + "\n";
                }
            }
            catch (IOException e) {                
                e.printStackTrace();
            }
            return true;


 }

and I call that into a text view.

add.append(""+ address()
            + '\n');

it works somewhat except for it doesn’t show the address and instead shows true

can any one tell me why this is?

thanks.

You need to initialize the result String variable outside the try block, then change the method’s return type to String and indeed return the result String variable after having augmented it with the lines from the address.

public String address() {
    Geocoder geoCoder = new Geocoder(getBaseContext(), Locale.getDefault());
    String result = "";
    try {
        List<Address> addresses =
            geoCoder.getFromLocation(LocationManagerHelper.getLatitude() / 1E6,
                                     LocationManagerHelper.getLongitude() / 1E6,
                                     1);
            if (addresses.size() > 0) {
                Address address = addresses.get(0);
                for (int i = 0; i < address.getMaxAddressLineIndex(); i++)
                    result += address.getAddressLine(i) + "\n";
            }
    } catch (IOException e) {
        e.printStackTrace();
    }
    return result;
}

But, really, this is basic Java programming, so before delving into a framework such as Android I would heartily suggest you learn the language first.
