This php page is the url string passed to get coordinates and markers. Please help me. Nice thanks This the java code: public class MapsActivity extends FragmentActivity implements OnMapReadyCallback { private GoogleMap mMap; private Double Latitude = 0.00; private Double Longitude = 0.00; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_maps); // Obtain the SupportMapFragment and get notified when the map is ready to be used. SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager() .findFragmentById(R.id.map); mapFragment.getMapAsync(this); new JSONTask().execute("http://192.168.1.101/crud/markers_android.php"); } @Override public void onMapReady(GoogleMap googleMap) { mMap = googleMap; } public class JSONTask extends AsyncTask<String, String, String> { @Override protected String doInBackground(String... params) { HttpURLConnection connection = null; BufferedReader reader = null; try { URL url = new URL(params[0]); connection = (HttpURLConnection) url.openConnection(); connection.connect(); InputStream stream = connection.getInputStream(); reader = new BufferedReader(new InputStreamReader(stream)); StringBuffer buffer = new StringBuffer(); String line = ""; while ((line = reader.readLine()) != null) { buffer.append(line); } String finalJson = buffer.toString(); JSONObject parentObject = new JSONObject(finalJson); JSONArray parentArray = new JSONArray(); //; //JSONArray parentArray = parentObject.getJSONArray(""); for (int i = 0; i<parentArray.length(); i++) { JSONObject finalObject = parentArray.getJSONObject(i); String lat = finalObject.getString("LAT"); Latitude = Double.parseDouble(lat.toString()); String lon = finalObject.getString("LON"); Longitude = Double.parseDouble(lon.toString()); Log.w("eeee", "Lat : " + lat + " Lon : " + lon); MarkerOptions marker = new MarkerOptions().position(new LatLng(Latitude, Longitude)); mMap.addMarker(marker); } } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (JSONException e) { e.printStackTrace(); } finally { if (connection != null) { connection.disconnect(); } try { if (reader != null) { reader.close(); } } catch (IOException e) { e.printStackTrace(); } } return null; } @Override protected void onPostExecute(String s) { super.onPostExecute(s); } } } Code php is here <http://pastebin.com/HEKxBCRd> -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
