How To Get Full Address From Passing Latitude And Latitude?

i used the code on my phone bellow to get address { country, street, city}, but it didnt work for many inputs, why? and sometimes crashing. please how to get the full address by p

Solution 1:

There is a known issue that Geocoder doesn't always returns a value. See Geocoder doesn't always return a value and geocoder.getFromLocationName returns only null. You can try to send a request 3 times in a for loop. It should be able to return atleast once. If not then, their might be a connection issue or can be other issues like server did not reply to your request. For me sometimes it never returned anything even if it was connected to internet. Then, I used this much more reliable way to get the address everytime:

//lat, lng are Double variables  containing latitude and longitude values. publicJSONObjectgetLocationInfo() {
        //Http RequestHttpGet httpGet = newHttpGet("http://maps.google.com/maps/api/geocode/json?latlng="+lat+","+lng+"&sensor=true");
        HttpClient client = newDefaultHttpClient();
        HttpResponse response;
        StringBuilder stringBuilder = newStringBuilder();

        try {
            response = client.execute(httpGet);
            HttpEntity entity = response.getEntity();
            InputStream stream = entity.getContent();
            int b;
            while ((b = stream.read()) != -1) {
                stringBuilder.append((char) b);
            }
        } catch (ClientProtocolException e) {
            } catch (IOException e) {
        }
                //Create a JSON from the String that was return.JSONObject jsonObject = newJSONObject();
        try {
            jsonObject = newJSONObject(stringBuilder.toString());
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return jsonObject;
    }

I called the function as follows to get the complete address:

JSONObject ret = getLocationInfo(); //Get the JSON that is returned from the API callJSONObject location;
String location_string;
//Parse to get the value corresponding to `formatted_address` key. try {
    location = ret.getJSONArray("results").getJSONObject(0);
    location_string = location.getString("formatted_address");
    Log.d("test", "formattted address:" + location_string);
} catch (JSONException e1) {
    e1.printStackTrace();

}

You can call this inside AsyncTask or a new thread. I used Asynctask for the same. Hope this helps.This worked for me. If you replace the URL with the lat and longitude coordinates and see the returned JSON object in a web browser. You'll see what just happened.
