Customize the android maps places? - android

I want show the maps of my places, based on a selection of area like business,favorites, etc.
I am using the following intent for search and display the result in the maps in Android
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps"));
startActivity(intent);
When I click the maps place as favorites it shows that place in my places.
How can I divide the places based on category in Android?


You should use the place api for getting the selection of area.
Step by step,
How to get the list of nearest place of a location.
Step 1 : Go to API Console for obtaining the Place API
https://code.google.com/apis/console/
and select on services tab
on the place service
now select API Access tab and get the API KEY
now you have a API key for getting place
Now in programming
*Step 2 * : first create a class named Place.java. This class is used to contain the property of place which are provided by Place api.
package com.android.code.GoogleMap.NearsetLandmark;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.json.JSONException;
import org.json.JSONObject;
public class Place {
private String id;
private String icon;
private String name;
private String vicinity;
private Double latitude;
private Double longitude;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getIcon() {
return icon;
}
public void setIcon(String icon) {
this.icon = icon;
}
public Double getLatitude() {
return latitude;
}
public void setLatitude(Double latitude) {
this.latitude = latitude;
}
public Double getLongitude() {
return longitude;
}
public void setLongitude(Double longitude) {
this.longitude = longitude;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getVicinity() {
return vicinity;
}
public void setVicinity(String vicinity) {
this.vicinity = vicinity;
}
static Place jsonToPontoReferencia(JSONObject pontoReferencia) {
try {
Place result = new Place();
JSONObject geometry = (JSONObject) pontoReferencia.get("geometry");
JSONObject location = (JSONObject) geometry.get("location");
result.setLatitude((Double) location.get("lat"));
result.setLongitude((Double) location.get("lng"));
result.setIcon(pontoReferencia.getString("icon"));
result.setName(pontoReferencia.getString("name"));
result.setVicinity(pontoReferencia.getString("vicinity"));
result.setId(pontoReferencia.getString("id"));
return result;
} catch (JSONException ex) {
Logger.getLogger(Place.class.getName()).log(Level.SEVERE, null, ex);
}
return null;
}
#Override
public String toString() {
return "Place{" + "id=" + id + ", icon=" + icon + ", name=" + name + ", latitude=" + latitude + ", longitude=" + longitude + '}';
}
}
Now create a class named PlacesService
package com.android.code.GoogleMap.NearsetLandmark;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
import java.util.ArrayList;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import android.util.Log;
public class PlacesService {
private String API_KEY;
public PlacesService(String apikey) {
this.API_KEY = apikey;
}
public void setApiKey(String apikey) {
this.API_KEY = apikey;
}
public List<Place> findPlaces(double latitude, double longitude,String placeSpacification)
{
String urlString = makeUrl(latitude, longitude,placeSpacification);
try {
String json = getJSON(urlString);
System.out.println(json);
JSONObject object = new JSONObject(json);
JSONArray array = object.getJSONArray("results");
ArrayList<Place> arrayList = new ArrayList<Place>();
for (int i = 0; i < array.length(); i++) {
try {
Place place = Place.jsonToPontoReferencia((JSONObject) array.get(i));
Log.v("Places Services ", ""+place);
arrayList.add(place);
} catch (Exception e) {
}
}
return arrayList;
} catch (JSONException ex) {
Logger.getLogger(PlacesService.class.getName()).log(Level.SEVERE, null, ex);
}
return null;
}
//https://maps.googleapis.com/maps/api/place/search/json?location=28.632808,77.218276&radius=500&types=atm&sensor=false&key=your_api_key
private String makeUrl(double latitude, double longitude,String place) {
StringBuilder urlString = new StringBuilder("https://maps.googleapis.com/maps/api/place/search/json?");
if (place.equals("")) {
urlString.append("&location=");
urlString.append(Double.toString(latitude));
urlString.append(",");
urlString.append(Double.toString(longitude));
urlString.append("&radius=1000");
// urlString.append("&types="+place);
urlString.append("&sensor=false&key=" + API_KEY);
} else {
urlString.append("&location=");
urlString.append(Double.toString(latitude));
urlString.append(",");
urlString.append(Double.toString(longitude));
urlString.append("&radius=1000");
urlString.append("&types="+place);
urlString.append("&sensor=false&key=" + API_KEY);
}
return urlString.toString();
}
protected String getJSON(String url) {
return getUrlContents(url);
}
private String getUrlContents(String theUrl)
{
StringBuilder content = new StringBuilder();
try {
URL url = new URL(theUrl);
URLConnection urlConnection = url.openConnection();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()), 8);
String line;
while ((line = bufferedReader.readLine()) != null)
{
content.append(line + "\n");
}
bufferedReader.close();
}
catch (Exception e)
{
e.printStackTrace();
}
return content.toString();
}
}
Now create a new Activity where you want to get the list of nearest places.

I think you must order date in ascendant mode, then add to series of DataPoint.

Do not access the Android UI toolkit from outside the UI thread
Pass editText_mail_id.getText() and editText_chat_message.getText() as parameters to your async task or set it in onPreExecute to some variable
Like :
private class SendMessage extends AsyncTask<String, Void, String> {
private String mailId;
private String msgText;
#Override
protected void onPreExecute() {
super.onPreExecute();
mailId = editText_mail_id.getText().toString();
msgText = editText_chat_message.getText().toString();
}
Change url in doInBackground as :
String url = Util.send_chat_url+"?email_id="+mailId+"&message="+msgText;

you can create class for storing your parameter like i do,
Just create one class
example :
public class MyTaskParams
{
String mailId;
String message;
public MyTaskParams(String mailId, String message)
{
this.mailId = mailId;
this.message = message;
}
}
public class SendMessage extends AsyncTask<MyTaskParams, Void, String {
#Override
protected String doInBackground(MyTaskParams... params) {
String mailId = params[0].mailId;
String message = params[0].message;
String url = Util.send_chat_url+"?email_id="+ mailId +"&message="+ message;
}
}
so you can just call like this
MyTaskParams params = new MyTaskParams(editText_mail_id.getText().toString(),editText_chat_message.getText().toString());
SendMessage myTask = new SendMessage();
myTask.execute(params);
with this code you can call SendMessage Class from any activity, dont bind your asynctask with get text because if you do that you just can use SendMessage only in that activity
Hope this can help you.

Refresh Android Google maps v2 after adding markers

I have an app which takes android map marker locations (lat/long) from mysql database. And user from my app can add markers too. The problem is that when user adds location of the new marker it does not appear on map. However the lat and long values appear in mysql database and if i reinstall the app it will show added location. Issue here seems to be that i have to refresh the map and i don't know how to do it in google maps v2. I found some answers that i should clear all markers and then load them again like this:
googleMap.clear();
But sadly it did not work. I found that in version one there was this method
map.invalidate();
Sadly in Google Maps v2 there is no such method. Has anyone have any idea how to refresh Google Maps v2 when i reactivate activity or if i press refresh button, any suggestion will be appreciated.

Since googleMap.appMarker() seems not to get called, you propaply catch an Exception when calling content.getRelation().equals("son").

toast mesage not shown on screen when network or server not available

AgAppHelperMethods isn't really an Activity. You've derived this class from Activity, but then you've created Singleton management methods (getInstance()) and you are instantiating it yourself. This is bad. Don't do this.
Normally Android controls the instantiation of activities. You don't ever create one yourself (with new).
It looks to me like AgAppHelperMethods just needs to be a regular Java class. It doesn't need to inherit from anything. Remove also the lifecycle methods like onCreate().
Now you will have a problem with the toast, because you need a context for that and AgAppHelperMethods isn't a Context. To solve that you can add Context as a parameter to AgAppXMLParser() like this:
public String[][] AgAppXMLParser(Context context, String parUrl) {
...
// Now you can use "context" to create your toast.
}
When you call AgAppXMLParser() from AgAppMenu just pass "this" as the context parameter.
