How to find latitude and longitude from an address?

Question

I want to show the location of the address on Google Maps.

How do I get the latitude and longitude of an address using the Google Maps API?

Answer 1

public GeoPoint getLocationFromAddress(String strAddress){ Geocoder coder = new Geocoder(this); List<Address> address; GeoPoint p1 = null; try { address = coder.getFromLocationName(strAddress,5); if (address==null) { return null; } Address location=address.get(0); location.getLatitude(); location.getLongitude(); p1 = new GeoPoint((double) (location.getLatitude() * 1E6), (double) (location.getLongitude() * 1E6)); return p1; } } 

strAddress is a string containing an address. The address variable contains the translated addresses.

Ud_an solution with updated API

Note The LatLng class is part of the Google Play Services.

Required :

 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> <uses-permission android:name="android.permission.INTERNET"/> 

Update. If you have a target SDK of 23 and above, make sure that you take care of allowing runtime for the location.

 public LatLng getLocationFromAddress(Context context,String strAddress) { Geocoder coder = new Geocoder(context); List<Address> address; LatLng p1 = null; try { // May throw an IOException address = coder.getFromLocationName(strAddress, 5); if (address == null) { return null; } Address location = address.get(0); p1 = new LatLng(location.getLatitude(), location.getLongitude() ); } catch (IOException ex) { ex.printStackTrace(); } return p1; }

If you want to put your address on google map then it will be easier for you to use the following

 Intent searchAddress = new Intent(Intent.ACTION_VIEW,Uri.parse("geo:0,0?q="+address)); startActivity(searchAddress); 

OR

if you need to get long long from your address, use Google Place Api after

create a method that returns a JSONObject with an HTTP call response as shown below

 public static JSONObject getLocationInfo(String address) { StringBuilder stringBuilder = new StringBuilder(); try { address = address.replaceAll(" ","%20"); HttpPost httppost = new HttpPost("http://maps.google.com/maps/api/geocode/json?address=" + address + "&sensor=false"); HttpClient client = new DefaultHttpClient(); HttpResponse response; stringBuilder = new StringBuilder(); response = client.execute(httppost); 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) { } JSONObject jsonObject = new JSONObject(); try { jsonObject = new JSONObject(stringBuilder.toString()); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } return jsonObject; } 

now pass that JSONObject to the getLatLong () method, for example, of the following

 public static boolean getLatLong(JSONObject jsonObject) { try { longitute = ((JSONArray)jsonObject.get("results")).getJSONObject(0) .getJSONObject("geometry").getJSONObject("location") .getDouble("lng"); latitude = ((JSONArray)jsonObject.get("results")).getJSONObject(0) .getJSONObject("geometry").getJSONObject("location") .getDouble("lat"); } catch (JSONException e) { return false; } return true; } 

Hope this helps you and others. !! Thank..!!

The following code will work for google apiv2:

 public void convertAddress() { if (address != null && !address.isEmpty()) { try { List<Address> addressList = geoCoder.getFromLocationName(address, 1); if (addressList != null && addressList.size() > 0) { double lat = addressList.get(0).getLatitude(); double lng = addressList.get(0).getLongitude(); } } catch (Exception e) { e.printStackTrace(); } // end catch } // end if } // end convertAddress 

Where the address is the String (123 Testing Rd City State zip) that you want to convert to LatLng.

Here's how you can find the latitude and longitude of where we click on the map.

 public boolean onTouchEvent(MotionEvent event, MapView mapView) { //---when user lifts his finger--- if (event.getAction() == 1) { GeoPoint p = mapView.getProjection().fromPixels( (int) event.getX(), (int) event.getY()); Toast.makeText(getBaseContext(), p.getLatitudeE6() / 1E6 + "," + p.getLongitudeE6() /1E6 , Toast.LENGTH_SHORT).show(); } return false; } 

It works well.

To get the location address, we can use the geocoder class.

The answer to the Kandhi problem above is:

It throws a "java.io.IOException service is unavailable" I already gave these permissions and turned on the library ... I can get a map view ... it throws this IOException on geocoding ...

I just added catch IOException after trying and solved the problem

  catch(IOException ioEx){ return null; }

 Geocoder coder = new Geocoder(this); List<Address> addresses; try { addresses = coder.getFromLocationName(address, 5); if (addresses == null) { } Address location = addresses.get(0); double lat = location.getLatitude(); double lng = location.getLongitude(); Log.i("Lat",""+lat); Log.i("Lng",""+lng); LatLng latLng = new LatLng(lat,lng); MarkerOptions markerOptions = new MarkerOptions(); markerOptions.position(latLng); googleMap.addMarker(markerOptions); googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng,12)); } catch (IOException e) { e.printStackTrace(); }
