Is it possible to use it as library project for my application,i want to use Android Google Maps real app search-ability functionality. How can i do it,is it possible?
Thanks in advance..
EDIT:
I have shown Google Map in my app successfully, I want to include Google Map search functionality means that I can able to search any location in the world in auto suggested field and by selecting a particular location and move marker to that location. so how can I?
I tried this and this but not getting auto suggested text why I don't know..
I want like:
step1: show map with search box
step2: while entering text it should auto suggest.
step3: when click on particular name move map to that location
You can easily provide that kind of search functionality by using Places API and Geocode API (Both will help you according to your usecase).
Read the below Documentation for your assistance.
GeoCode API
Places API
I would recommend to use Places API for your need ( As per my observation on your usecase). But you could also use geocode, If you needed.
Many working reference and examples are there.
For startup, below are my reference :
PlacesAPI AutoComplete feature, Hotel Finder with Autocomplete
GeocodeAPI Simple GeoCoding
NOTE :
I have suggested javascript API. But not sure whether it will help you in Android environment (I dont know anything about android environment).
No single Api can help you have to use multiple google api's
Step1. Implement Google Place autocomplete Read this
Step2. You have to geocode means you have to convert address to latitude and longitude check this
Step3. Now You can plot these lat-long on the map.
This works for me.
I think you should take a look at the Google Maps API for Android at https://developers.google.com/maps/documentation/android/
The Google Search Appliance doesn't have any mapping or geo search features right now.
This is how I did it ---
Android Manifest file should contain the following lines:
<uses-library
android:name="com.google.android.maps"
android:required="true" >
</uses-library>
<!-- You must insert your own Google Maps for Android API v2 key in here. -->
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="<put your api key value here>" />
Location XML file should have the following apart from anything extra:
<fragment
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Location java file should have something like this:
View mapView = null;
private GoogleMap mMap;
mMap = supportMapFragment.getMap();
mapView = (View) view.findViewById(R.id.map);
SupportMapFragment supportMapFragment = (SupportMapFragment) fragmentManager
.findFragmentById(R.id.map);
if(mMap != null){
mMap.setMyLocationEnabled(true);
}
if(mMap != null)
mMap.setOnMapLongClickListener(new GoogleMap.OnMapLongClickListener() {
#Override
public void onMapLongClick(LatLng latLng) {
new EditMap().execute("", String.valueOf(latLng.latitude), String.valueOf(latLng.longitude));
}
});
class EditMap extends AsyncTask<String, String, String> {
/**
* Before starting background thread Show Progress Dialog
* */
#Override
protected void onPreExecute() {
super.onPreExecute();
}
/**
* getting Albums JSON
* */
protected String doInBackground(String... args) {
String address = args[0];
double latitude = Double.parseDouble(args[1]);
double longitude = Double.parseDouble(args[2]);
return editMap(address, latitude, longitude);
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(String result) {
if(!result.equals(""))
ToastUtil.ToastShort(getActivity(), result);
else {
mMap.clear();
mMap.addMarker(new MarkerOptions().position(new LatLng(lat, lng)).title(attvalue));
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(lat, lng), 11));
}
}
}
NOTE:
These are the minimal requirements for the setting of location as you choose from Map that fills the location in your text.
There is a background thread that runs as you long press the location in a map.
The listener defined for that is setOnMapLongClickListener as you see above.
The execution will place the marker to the exact location you chose to mark as set.
There will be a done button after you have chosen the location by a marker. This done button will confirm what you have chosen and will set that on a textfield for you.
The above code uses the method editMap to edit the map location.
The implementation is as done here:
private String editMap(String address, double latitude, double longitude ) {
String keyword = null;
try {
Geocoder geocoder = new Geocoder(getActivity(), Locale.getDefault());
if(!address.equals("")){
keyword = address;
java.util.List<android.location.Address> result = geocoder
.getFromLocationName(keyword, 1);
if (result.size() > 0) {
lat = (double) result.get(0).getLatitude();
lng = (double) result.get(0).getLongitude();
attvalue = address;
} else {
return "Record not found";
}
} else {
String sUrl = "http://google.com/maps/api/geocode/json?latlng="+latitude+","+longitude+"&sensor=true";
DefaultHttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet(sUrl);
HttpResponse r = client.execute(get);
int status = r.getStatusLine().getStatusCode();
if(status == 200){
HttpEntity e = r.getEntity();
String data = EntityUtils.toString(e);
try{
JSONObject jsonObject = new JSONObject(data);
JSONArray results = jsonObject.getJSONArray("results");
JSONObject addressObject = results.getJSONObject(0);
JSONArray addressComp = addressObject.getJSONArray("address_components");
String city = "", state = "";
for(int i=0; i < addressComp.length(); i++){
JSONArray types = addressComp.getJSONObject(i).getJSONArray("types");
if(city.equals("") && types.getString(0).equals("locality"))
city = addressComp.getJSONObject(i).getString("long_name");
if(state.equals("") && types.getString(0).equals("administrative_area_level_1"))
state = addressComp.getJSONObject(i).getString("long_name");
if(!city.equals("") && !state.equals(""))
break;
}
attvalue = city + ", " + state;
} catch (JSONException e1) {
e1.printStackTrace();
}
lat = latitude;
lng = longitude;
}else{
return "Location Not Found";
}
}
} catch (IOException io) {
return "Connection Error";
}
return "";
}
I hope this is enough to help you out.

I have been trying to display a shapefile using openmap library. On click of a button on first activity, the application goes to the second activity (which is also the second page) but then it suddenly crashes.
I ran the debugger and realised that mapFragment variable was still null, it was getting the value from findFragmentById.

I am a newbie in android dev, please be patient with me. Many thanks!
The OpenMap Library is used for Java Swing and JFrame applications and can't be used in an Android application as far as I can tell. The Google Map SDK has everything you need to display Maps in an Android Application including getting device location, displaying Places info, setting map markers, polylines, and polygons. Getting location updates in the backgroud, etc... To set it up, create a new Maps Activity from the Gallery. It will generate all the needed files for you and give you a list of instructions to get an API Key so that Maps can be used in your app. Here is a question explaining the security of your api key that I answered a while back. Google Maps Docs explains all the basic functionality of how to get Maps setup. I would recommend you visit some YouTube Tutorials on how to set Maps up in your Android application.
<--EDIT-->
Here is an answer I found on Stack Overflow from about two years ago. It doesn't really use the OpenMap Libray, but it's a workaround. You can pull ShapeFile data and use it in Google Maps Polygon, Polyline, and LatLng classes and display those on a map in your android application.
I am using Google Directions API to get routes between two locations with Way Points.
Currently what I am doing is getting direction details between two locations using Direction API and showing the result in Google Maps integrated inside my application. It works well as expected. This is how I did it:
private DirectionsResult getDirectionsDetails(String origin,String destination,TravelMode mode) {
Log.i("testtt"," Origin "+origin+" Destination "+destination);
DateTime now = new DateTime();
try {
return DirectionsApi.newRequest(getGeoContext())
.mode(mode)
.origin(origin)
.waypoints(waypoints.toArray(new String[0]))
.destination(destination)
.departureTime(now)
.await();
} catch (InterruptedException e) {
e.printStackTrace();
return null;
} catch (IOException e) {
e.printStackTrace();
return null;
} catch (com.google.maps.errors.ApiException e) {
e.printStackTrace();
return null;
}
}
#Override
public void onMapReady(GoogleMap googleMap) {
setupGoogleMapScreenSettings(googleMap);
DirectionsResult results = getDirectionsDetails(origin,destination,TravelMode.DRIVING);
if (results != null) {
addPolyline(results, googleMap);
positionCamera(results.routes[overview], googleMap);
addMarkersToMap(results, googleMap);
}
}
private void setupGoogleMapScreenSettings(GoogleMap mMap) {
mMap.setBuildingsEnabled(true);
mMap.setIndoorEnabled(true);
mMap.setTrafficEnabled(true);
UiSettings mUiSettings = mMap.getUiSettings();
mUiSettings.setZoomControlsEnabled(true);
mUiSettings.setCompassEnabled(true);
mUiSettings.setMyLocationButtonEnabled(true);
mUiSettings.setScrollGesturesEnabled(true);
mUiSettings.setZoomGesturesEnabled(true);
mUiSettings.setTiltGesturesEnabled(true);
mUiSettings.setRotateGesturesEnabled(true);
}
private void addMarkersToMap(DirectionsResult results, GoogleMap mMap) {
mMap.addMarker(new MarkerOptions().position(new LatLng(results.routes[overview].legs[overview].startLocation.lat,results.routes[overview].legs[overview].startLocation.lng)).title(results.routes[overview].legs[overview].startAddress));
mMap.addMarker(new MarkerOptions().position(new LatLng(results.routes[overview].legs[overview].endLocation.lat,results.routes[overview].legs[overview].endLocation.lng)).title(results.routes[overview].legs[overview].endAddress).snippet(getEndLocationTitle(results)));
}
private void positionCamera(DirectionsRoute route, GoogleMap mMap) {
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(route.legs[overview].startLocation.lat, route.legs[overview].startLocation.lng), 12));
}
private void addPolyline(DirectionsResult results, GoogleMap mMap) {
List<LatLng> decodedPath = PolyUtil.decode(results.routes[overview].overviewPolyline.getEncodedPath());
mMap.addPolyline(new PolylineOptions().addAll(decodedPath));
}
But what I want is I want to load this direction result in the external Google Maps app. What I am asking is is there any way to pass the DirectionsResult object to Google Maps application via Intent so that it will show the routes in the app.
Reason why I want this is to avoid integrating Google Maps API to the project as it is not completely free anymore.
Pricing details
As I can see in your code, that you are not performing any calculations on the DirectionsDetails given by DirectionsApi you can open the pass your location coordinates in google maps.
By default, Google maps always loads the best available route according to current traffic and time:
String geoUri = "http://maps.google.com/maps?q=loc:" + lat + "," + lng + " (" + mTitle + ")";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(geoUri));
context.startActivity(intent);
If you want to add waypoints in between your source and destination you can have a look at this answer.
If you want, you can find the route through DirectionsApi and process the data for your internal analytics for eg. approx time to travel between his location and new location, distance etc.
I have an activity implementing OnMapReadyCallback to display some markers.
Before opening the map i provide a target city which i'd like to look at closer on the map basically by calling :
LatLng currentCity = new LatLng(cityLat,cityLng)
CameraUpdate location = CameraUpdateFactory.newLatLngZoom(currentCity,13);
googleMap.animateCamera(location);
The main problem here is that the zoom level is just an arbitrary number which works fine for some city and bad for others (Too zoomed in, Not enough zoomed in).
What i would like to achieve is to determine the zoom level dynamically depending on the city in the same way Google Maps does.
I know that the bigger the ViewPort of the city is, the smaller the zoom needs to be but i can't find a method to get the ViewPort for a given city and then changing the zoom level accordingly
EDIT : I was thinking about using a Geocoder to get a list of adress using the latitude and longitude of the city using
List<Address> addresses = mGeocoder.getFromLocation(Lat,Lon,maxLimit);
and then iterating over this list to find out the outermost adresses avaible for that city, in order to build a LatLngBounds to pass at setLatLngBoundsForCameraTarget() method.
The main problem with this approach is that, once again, the "maxLimit" is arbitrary and needs to be quite big for a big city, eventually returning a really big List
You can retrieve a view port for the city from the Geocoding API reverse geocoding response.
You should execute HTTP request to retrieve city view port from your activity. Once you receive the response you can construct the LatLngBounds instance and move camera accordingly.
Sample reverse geocoding request that gets city from coordinates is the following
https://maps.googleapis.com/maps/api/geocode/json?latlng=47.376887%2C8.541694&result_type=locality&key=YOUR_API_KEY
I wrote a small example for Map activity that receives lat and lng from the intent, executes the reverse geocoding HTTP request using the Volley library and moves camera to show the city view port.
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
private float lat;
private float lng;
private String name;
private RequestQueue mRequestQueue;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent i = getIntent();
this.lat = i.getFloatExtra("lat", 0);
this.lng = i.getFloatExtra("lng", 0);
this.name = i.getStringExtra("name");
mRequestQueue = Volley.newRequestQueue(this);
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);
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
// Add a marker in Sydney and move the camera
LatLng pos = new LatLng(this.lat, this.lng);
mMap.addMarker(new MarkerOptions().position(pos).title(this.name));
mMap.moveCamera(CameraUpdateFactory.newLatLng(pos));
this.fetchReverseGeocodeJson();
}
private void fetchReverseGeocodeJson() {
// Pass second argument as "null" for GET requests
JsonObjectRequest req = new JsonObjectRequest(Request.Method.GET,
"https://maps.googleapis.com/maps/api/geocode/json?latlng=" + this.lat + "%2C" + this.lng + "&result_type=locality&key=AIzaSyBrPt88vvoPDDn_imh-RzCXl5Ha2F2LYig",
null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
String status = response.getString("status");
if (status.equals("OK")) {
JSONArray results = response.getJSONArray("results");
JSONObject item = results.getJSONObject(0);
JSONObject geom = item.getJSONObject("geometry");
JSONObject bounds = geom.getJSONObject("viewport");
JSONObject ne = bounds.getJSONObject("northeast");
JSONObject sw = bounds.getJSONObject("southwest");
LatLngBounds mapbounds = new LatLngBounds(new LatLng(sw.getDouble("lat"),sw.getDouble("lng")),
new LatLng(ne.getDouble("lat"), ne.getDouble("lng")));
mMap.moveCamera(CameraUpdateFactory.newLatLngBounds(mapbounds, 0));
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.e("Error: ", error.getMessage());
}
}
);
/* Add your Requests to the RequestQueue to execute */
mRequestQueue.add(req);
}
}

i have to show multiple location on the Native Google Map Application (MapView is not implemented in our application ).i have all the lat- long of all the geo Points . how can i pass the intent to show the multiple points on Native Google Map Application.
i know to show a point on Google map using the following Code.
String uri = String.format(Locale.ENGLISH, "geo:%f,%f", latitude, longitude);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
context.startActivity(intent);
please suggest how to do the needful changes.
Thanks :)
You can pass the names of the places that you want to show in the Map from the other Activity to the present Activity and then implement Markers to show them in the Map. For this you have to implement Google Map in the present Activity and I hope you have done that. :)
The below code shows multiple locations on a Google Map:
private void AddMarkers(GoogleMap googleMap)
{
try {
Intent intent = getIntent();
Bundle extras = intent.getExtras();
Geocoder geocoder = new Geocoder(context);
Origin_Map = extras.getString(MainActivity.ORIGIN_MAP);
Destination_Map = extras.getString(MainActivity.DESTINATION_MAP);
Addr_Origin = geocoder.getFromLocationName(Origin_Map, 1);
Addr_Dest = geocoder.getFromLocationName(Destination_Map, 1);
if (Addr_Origin.size() > 0) {
latitude_origin = Addr_Origin.get(0).getLatitude();
longitude_origin = Addr_Origin.get(0).getLongitude();
}
if (Addr_Dest.size() > 0) {
latitude_destination = Addr_Dest.get(0).getLatitude();
longitude_destination = Addr_Dest.get(0).getLongitude();
}
Marker m1 = googleMap.addMarker(new MarkerOptions().position(new LatLng(latitude_origin, longitude_origin)).title(Origin_Map).icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_ORANGE)));
Marker m2 = googleMap.addMarker(new MarkerOptions().position(new LatLng(latitude_destination, longitude_destination)).title(Destination_Map).icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN)));
} catch (Exception e) {
e.printStackTrace();
}
}
And call this method once your map is ready!
#Override
public void onMapReady(GoogleMap googleMap)
{
AddMarkers(googleMap);
}
Hope this helps!!
Judging by this it is not possible. Also the question is a duplicate of this.
I am following a tutorial here https://code.google.com/p/osmbonuspack/wiki/Tutorial_1 but I have encountered an error that it doesn't show the correct route correctly. It just shows a straight line from Point A to Point B.
What I want to achieve is to show the correct route from these points. I'm guessing the error is that it doesn't recognize any nodes to go through.
A similar question has been also asked and I am assuming I have the same problem if I haven't explained my question well.

Let's try to provide a complete answer to this quite frequent question.
Basically, when you get the "straight line", it means that the RoadManager got an error.
So, first of all, in your code, you should check the result of getRoad, this way:
if (road.mStatus != Road.STATUS_OK){
//handle error... warn the user, etc.
}
Now, where this error is coming from?
=> You must search in the logcat. You should find the full url that has been sent, and probably a stacktrace about the error.
I strongly recommend that you copy/paste this full url in a browser , and check the result.
Here are the typical errors, by decreasing probability:
1) You didnt' read carefully the "Important note" at the beginning of the Tutorial_0, and you are trying to do a Network call in the main thread, with an SDK >= 3.0.
=> Read this "Important note".
2) You asked for a route that is not possible (really not possible, or because of weird positions, or because of setting unsupported options).
=> This is easy to check by copy/pasting the full url in a web browser, and looking at the answer.
3) Your device has no network connectivity.
4) The routing service changed its API (this happened, more than once...).
=> Could be checked by copy/pasting the full url in a browser.
In this case, raise an Issue in OSMBonusPack project, so that we can take it into account ASAP.
5) The routing service is down.
=> Easy to check by copy/pasting the full url in a browser.
I think it is better to use AsyncTasks in this case:
/**
* Async task to get the road in a separate thread.
*/
private class UpdateRoadTask extends AsyncTask<Object, Void, Road> {
protected Road doInBackground(Object... params) {
#SuppressWarnings("unchecked")
ArrayList<GeoPoint> waypoints = (ArrayList<GeoPoint>)params[0];
RoadManager roadManager = new OSRMRoadManager();
return roadManager.getRoad(waypoints);
}
#Override
protected void onPostExecute(Road result) {
road = result;
// showing distance and duration of the road
Toast.makeText(getActivity(), "distance="+road.mLength, Toast.LENGTH_LONG).show();
Toast.makeText(getActivity(), "durée="+road.mDuration, Toast.LENGTH_LONG).show();
if(road.mStatus != Road.STATUS_OK)
Toast.makeText(getActivity(), "Error when loading the road - status="+road.mStatus, Toast.LENGTH_SHORT).show();
Polyline roadOverlay = RoadManager.buildRoadOverlay(road,getActivity());
map.getOverlays().add(roadOverlay);
map.invalidate();
//updateUIWithRoad(result);
}
}
then call it new UpdateRoadTask().execute(waypoints);
new Thread(new Runnable()
{
public void run()
{
RoadManager roadManager = new OSRMRoadManager();
ArrayList<GeoPoint> waypoints = new ArrayList<GeoPoint>();
GeoPoint startPoint = new GeoPoint(source_lat, source_longi);
waypoints.add(startPoint);
GeoPoint endPoint = new GeoPoint(desti_lat,desti_longi);
waypoints.add(endPoint);
try
{
road = roadManager.getRoad(waypoints);
}
catch (Exception e)
{
e.printStackTrace();
}
runOnUiThread(new Runnable()
{
public void run()
{
if (road.mStatus != Road.STATUS_OK)
{
//handle error... warn the user, etc.
}
Polyline roadOverlay = RoadManager.buildRoadOverlay(road, Color.RED, 8, context);
map.getOverlays().add(roadOverlay);
}
});
}
}).start();
And i am use two jar files 1)slf4j-android-1.5.8.jar and 2)osmdroid-android-4.2.jar and osmbonuspack library.
A strange error I found regarding this is as follows:
Firstly I mention following line of code for taking directions for the vehicle "BIKE"
((OSRMRoadManager) roadManager).setMean(OSRMRoadManager.MEAN_BY_BIKE);
Now when it was first called it follows the following URL:
https://routing.openstreetmap.de/routed-car/route/v1/driving/68.8889678000,23.2151582000;73.1808008000,22.3110728000?alternatives=false&overview=full&steps=true
Now when calling the second time{same MEAN_BY_BIKE}, it is following this URL:
:https://routing.openstreetmap.de/routed-bike/route/v1/driving/68.8889678000,23.2151582000;73.1808008000,22.3110728000?alternatives=false&overview=full&steps=true
So the issue is that no response is for the "routed-bike" and it is calling automatically itself when called for second time.
So as a solution I changed my code to the following:
((OSRMRoadManager) roadManager).setMean(OSRMRoadManager.MEAN_BY_CAR);
You can check your LogCat for the same.
