Android: Error on Marker at GoogleMaps - android

I'm trying to get Latitude, Longitude and Name from a SQL Query on Java.
The problem is, when i call the Ubic() function, i get this error:
http://i.imgur.com/QD7JZjRh.jpg
http://i.imgur.com/xvzJ9ckh.jpg
This is the code that i added an the error is caused by String Latlon[][] = com.Ubic();
public class BuscarContrincantes extends FragmentActivity implements
LocationListener {
GoogleMap googlemapa;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.buscarcontrincante);
SupportMapFragment maps = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
googlemapa = maps.getMap();
googlemapa.setMyLocationEnabled(true);
googlemapa.setMapType(GoogleMap.MAP_TYPE_HYBRID);
googlemapa.getUiSettings().setCompassEnabled(true);
googlemapa.getUiSettings().setZoomControlsEnabled(true);
googlemapa.getUiSettings().setAllGesturesEnabled(true);
double latitud;
double longitud;
String nombre;
Datos com = new Datos();
String latlon[][] = com.Ubic(); //HERE IS THE PROBLEM!
for (int i = 0; i < latlon.length - 1; i++) {
latitud = Double.parseDouble(latlon[i][0]);
longitud = Double.parseDouble(latlon[i][3]);
nombre = (latlon[i][2]);
LatLng posicion = new LatLng(latitud, longitud);
googlemapa.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory
.fromResource(R.drawable.icono_canchas))
.position(posicion).title(nombre));
}
}
The file Datos.java is what i called from the Main Thread.
public class Datos {
public String[][] Ubic() {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"http://MY.IP/FOLDER/QUERY.php");
try {
HttpResponse response = httpclient.execute(httppost);
String jsonResult = inputStreamToString(
response.getEntity().getContent()).toString();
JSONObject object = new JSONObject(jsonResult);
JSONArray arr = object.getJSONArray("products");
String[] lat = new String[arr.length()+1];
String[] lon = new String[arr.length()+1];
String[] nombre = new String[arr.length() + 1];
String[][] latlon = new String[arr.length() + 1][5];
for (int i = 0; i < arr.length(); i++) {
lat[i] = arr.getJSONObject(i).getString("latitude");
lon[i] = arr.getJSONObject(i).getString("longitude");
name[i] = arr.getJSONObject(i).getString("name");
latlon[i][0] = lat[i];
latlon[i][6] = lon[i];
latlon[i][2] = name[i];
}
return latlon;
} catch (JSONException e) {
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
return null;
}
private static String parse(String string) {
return null;
}
private StringBuilder inputStreamToString(InputStream is) {
String rLine = "";
StringBuilder answer = new StringBuilder();
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
try {
while ((rLine = rd.readLine()) != null) {
answer.append(rLine);
}
} catch (IOException e) {
}
return answer;
}}
How can i solve this?

NetworkOnMainThreadException: This exception is thrown when an application attempts to perform a networking operation (HTTP request in your case) on its main thread.
You should call com.Ubic(); method on asynctask then only above code will work.

Nothing happens in the try

In this activity, i get places nearby and add them to a listview. I wanted also to add the place's phone number in an arrayList like the other datas, so i had to use place details request. So, i get all the place_id for all the places from the arrayList and launch the query to get the details (phone number). The problem is in class "readFromGooglePlaceDetailsAPI", it goes in the "try" and goes out with nothing happening, i don't know why!!! I only can see "IN TRY !!!" and then "----" from the println.
Is my sequence not right?
Where is the problem and what is the solution ?

Note that the getJSONArray() function throws an Exception if the mapping fails. For example I can't find a JSON Array which is called results.
The most important thing you have to do at first is:
change:
catch (Exception e) {
}
to
catch (Exception e) {
Log.e(YOUR_TAG, "Exception ..." , e);
}
Your try throws an Exception which you don't even Log. That might be the reason why you are confused.

How not to affect the UI when executing an AsyncTask?

I have an issue, which is not that big, but to the user it is bad.
The app basically gets the user's input of some place and, when the user clicks on the button, a URL to the Google API with the place on its parameter is sent to an AsyncTask, where it sends this URL via HttpGet and is returned a JSONArray with everything needed. The problem is, when I click on the button and the internet is not that good, the button seems to "freeze" like this:
My activity code is below:
public class MainActivity extends Activity{
...
protected void onCreate(Bundle savedInstanceState){...}
public void onResume()}
btnSearch.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
String search = txtSearch.getText().toString();
try{
List<Location> locations = new SearchTask(MainActivity.this).execute(strSearch).get();
if(locations != null){
ArrayAdapter<Location> adapter = new ArrayAdapter<Location>(MainActivity.this, android.R.layout.simple_list_item_1, locations);
listView.setAdapter(adapter);
...
}
}
}
}
}
}
My AsyncTask class code is below:
public class SearchTask extends AsyncTask<String, Void, List<Location>>{
...
protected List<Location> doInBackground(String... params){
if(isNetworkAvailable()){
HttpGet httpGet = null;
HttpClient client = null;
HttpResponse response = null;
StringBuilder builder = null;
try{
String param = URLDecoder.decode(params[0], "UTF-8").replace(" ", "%20");
httpGet = new HttpGet("http://maps.googleapis.com/maps/api/geocode/json?address=" + param + "&sensor=false");
client = new DefaultHttpClient();
builder = new StringBuilder();
}
catch(UnsupportedEncodingException e){
Log.i("Error", e.getMessage());
}
try{
response = client.execute(httpGet);
HttpEntity entity = response.getEntity();
InputStream stream = entity.getContent();
BufferedReader br = new BufferedReader(new InputStreamReader(stream, "UTF-8"));
int val;
while((val = br.read()) != -1){
builder.append((char) val);
}
}
catch(IOException e){
Log.i("Error", e.getMessage());
}
JSONObject jsonObject = new JSONObject();
List<Location> listLocation = new ArrayList<Location>();
int countJson = 0;
try{
jsonObject = new JSONObject(builder.toString());
JSONArray jArray = jsonObject.getJSONArray("results");
countJson = jArray.length();
for(int i = 0; i < countJson; i++){
Location location = new Location();
String formattedAddress = ((JSONArray) jsonObject.get("results")).getJSONObject(i).getString("formatted_address");
double lat = ((JSONArray) jsonObject.get("results")).getJSONObject(i).getJSONObject("geometry").getJSONObject("location").getDouble("lat");
double lng = ((JSONArray) jsonObject.get("results")).getJSONObject(i).getJSONObject("geometry").getJSONObject("location").getDouble("lng");
location.setFormattedAddress(formattedAddress);
location.setLat(lat);
location.setLng(lng);
listLocation.add(location);
}
}
catch(JSONException e){
Log.i("Error", e.getMessage());
}
return listLocation;
}
else{
return null;
}
}
#Override
protected void onPreExecute(){
super.onPreExecute();
progress = new ProgressDialog(context);
progress.setMessage("Loading...");
progress.show();
}
#Override
protected void onPostExecute(List<Location> result){
super.onPostExecute();
progress.dismiss();
}
private boolean isNetworkAvailable(){
ConnectivityManager connManager = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = connManager.getActiveNetworkInfo();
return info != null && info.isConnected();
}
}
The ListView is on the same xml of the EditView and the Button.
Is there a way to improve it in order to make the UI not behave like this?
Thanks!
Try this:
btnSearch.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
String search = txtSearch.getText().toString();
new SearchTask(MainActivity.this).execute(strSearch);
}
}
#Override
protected void onPostExecute(List<Location> locations){
if(locations != null){
ArrayAdapter<Location> adapter = new ArrayAdapter<Location>(MainActivity.this, android.R.layout.simple_list_item_1, locations);
listView.setAdapter(adapter);
}
progress.dismiss();
}

Issue with draw a path through markers

In my app it's possibile to insert markers with touch and then it's possible to calculate the path through these markers with subsequent HTTP requests.
The issue is that very often the first markers is skipped and between the last two markers is drawn a segment too.
Here's the code:
public class MultipleTracksDrawer extends AbstractDrawer {
private static final String TAG_LOG = MultipleTracksAsyncTask.class.getName();
private boolean flag = false;
void draw() {
for(int i = 0; i < markers.size() - 1; i++) {
Marker firstMarker = markers.get(i);
Marker secondMarker = markers.get(i + 1);
//I extract latitude and longitude from the markers
LatLng firstLatLng = new LatLng(firstMarker.getPosition().latitude, firstMarker.getPosition().longitude);
LatLng secondLatLng = new LatLng(secondMarker.getPosition().latitude, secondMarker.getPosition().longitude);
//Url for the request
String URL = Utilities.getInstance().makeURL(firstLatLng.latitude, firstLatLng.longitude,
secondLatLng.latitude, secondLatLng.longitude, travelMode);
//At the end of the markers list i set the flag as true for draw the path
if(i == markers.size() - 2) {
flag = true;
}
MultipleTracksAsyncTask multipleTracksAsyncTask = new MultipleTracksAsyncTask(URL);
multipleTracksAsyncTask.execute();
}
}
private class MultipleTracksAsyncTask extends AsyncTask<Void,Void,String> {
private ProgressDialog mDialog;
private String URL;
public MultipleTracksAsyncTask(String URL) {
this.URL = URL;
}
protected void onPreExecute() {
mDialog = ProgressDialog.show(context, "", "Loading...", true);
}
protected void onPostExecute(String result) {
if(mDialog != null) {
if(mDialog.isShowing()) {
mDialog.dismiss();
}
}
if(result != null) {
parseJSON(result);
//I draw the path only if the flag is true
if(flag) {
drawPath();
}
}
}
public String doInBackground(Void... param) {
JSONRequest jParser = new JSONRequest();
String json = jParser.getJSONFromUrl(URL,connectionTimeout,dataTimeout);
return json;
}
}
private void parseJSON(String result) {
try {
final JSONObject json = new JSONObject(result);
//I get "routes" array
JSONArray routeArray = json.getJSONArray("routes");
JSONObject routes = routeArray.getJSONObject(0);
JSONArray legsArray = routes.getJSONArray("legs");
JSONObject legsObject = legsArray.getJSONObject(0);
//I get distance and duration of the path
JSONObject distance = legsObject.getJSONObject("distance");
JSONObject duration = legsObject.getJSONObject("duration");
JSONObject overviewPolylines = routes.getJSONObject("overview_polyline");
String encodedString = overviewPolylines.getString("points");
//Decoding
model.getMarkersTrack().addAll(Utilities.getInstance().decodePoly(encodedString));
mTrackDistance += distance.getInt("value");
mTrackDuration += duration.getInt("value");
}
catch (JSONException e) {
e.printStackTrace();
Toast.makeText(context, "The path is not available", Toast.LENGTH_SHORT).show();
}
}
private void drawPath() {
for(int i = 0; i < model.getMarkersTrack().size() - 1; i++) {
LatLng src = model.getMarkersTrack().get(i);
LatLng dest = model.getMarkersTrack().get(i + 1);
PolylineOptions polylineOptions = new PolylineOptions()
.add(new LatLng(src.latitude, src.longitude), new LatLng(dest.latitude, dest.longitude))
.width(5)
.color(Color.BLUE).geodesic(true);
Polyline polyline = googleMap.addPolyline(polylineOptions);
//I save the polylines
model.getTrackPolylines().add(polyline);
}
}
}
I put here the code for the HTTP request too:
public class JSONRequest {
private InputStream is = null;
private String json = "";
/**
* Method that makes the HTTP request
*
* #param url URL of the HTTP request
* #param connectionTimeout timeout for the connection
* #param dataTimeout timeout for the download
* #return
*/
public String getJSONFromUrl(String url, int connectionTimeout, int dataTimeout) {
try {
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams,connectionTimeout);
HttpConnectionParams.setSoTimeout(httpParams, dataTimeout);
DefaultHttpClient httpClient = new DefaultHttpClient(httpParams);
//GET request
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpGet);
//I get the response
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
//I read the response
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
json = sb.toString();
is.close();
} catch (Exception e) {
e.printStackTrace();
}
return json;
}
}
Here's a picture: http://imageshack.com/a/img835/504/m0fc.png
UPDATE:
Problem fixed!
Now i create a new String URL in the draw() method of MultipleTracksDrawer class and i give it to the AsyncTask (as input parameter). In this way it works. I edited the code.

how to get json data from framework (Yii)

i'm trying to get json data from website that i build using Yii framework.
when i open mozilla and i go to http://localhost/restayii/index.php/employee/getemployee?id it's showing employee json data.
this is my employee jsondata :

(On Android)
The problem is:
when this app launch, and i clicked button refresh, it's not showing table row that contains employee json data. but there's no error too on the logcat. Is it wrong with my url on class Task extends AsyncTask http://10.0.2.2/restayii/protected/controllers/EmployeeController.php ??
or should i replaced it with the same link just when i open it from mozilla http://localhost/restayii/index.php/employee/getemployee?id??
Edit:
I already change the url to http://localhost/restayii/index.php/employee/getemployee?id inside Task Class extends AsyncTask, but is still won't get employee json data from localhost.
please, Any help would be greatly apreciated. thanks
i already find an answer. my problem is in sub class Task extends asyntask and also in jsonParser sub class.
private class Task extends AsyncTask<JSONObject, Void, JSONObject>{
#Override
protected JSONObject doInBackground(JSONObject... params) {
try {
JSONParser json_parser = new JSONParser();
json_object = json_parser.getJson(url);
} catch (Exception e) {
e.printStackTrace();
}
return json_object;
}
#Override
protected void onPostExecute(JSONObject result){
LoadEmployee(result);
}
}
private class JSONParser {
.....
public JSONObject getJson(String url) {
try {
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpget);
BufferedReader rd = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent()));
StringBuffer hasil = new StringBuffer();
String line = "";
while ((line = rd.readLine()) != null) {
hasil.append(line);
}
json = hasil.toString();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
e.printStackTrace();
}
return jObj;
}
}
now i can get all json data from my Yii web service. hope it will help someone.
I know that, you have to refresh android screen when you called an ajax data...
May be this will show you the way...
Now you use wrong URL in the AsyncTask. The right URL is something like http://localhost/restayii/index.php/employee/getemployee?id
