Android :: GeoCoder: GetFromLocationName
Jul 24, 2010
I wanted to make an app that displays the map, for example, Pizza in San Francisco, CA, United States, as well as in maps.google.com: http://maps.google.com/maps?f=q&source=s_q&hl=pt-BR&geocode=&q=Pizza+...
How do I do that?
I tried this: adresses = geoCoder.getFromLocationName addresses = ( "Pizza in San Francisco, CA, United States", 5); but does not work.
And this function will only return addresses, does not return the url images. Probably I need to use a different function, but which one?

I am trying to get the geo codes for an address.
I am using: Geocoder geocoder = new Geocoder(GeoNoteEditor.this, Locale .getDefault()); List<Address> addressList = null; addressList = geocoder.getFromLocationName(addressString, 1);
The problem is that I am getting an IOException sometimes when I call getFromLocationName for the same addressString. This does not happen all the time. When I get the IOException, if I repeat the getFromLocation call, sometimes it works sometimes I get the IOException again.
How do I prevent the IOException from happening?

How can I convert a street address into a latitude + longitude? I've tried to use Geocoder.getFromLocationName() with a bounding box, but all results I get are outside of the box. Is there a way to limit the hits to a certain area on earth?

Geocoder getFromLocationName is not returning anything if I'm searching for business places. Here are my finding so far:
CODE:..............
I've tested this on 1.6, 2.1 and 2.2 devices that has Google Maps.
I'm trying to find if there's a limitation explained somewhere on the SDK, but there is none except:
The amount of detail in a reverse geocoded location description may vary, for example one might contain the full street address of the closest building, while another might contain only a city name and postal code. The Geocoder class requires a backend service that is not included in the core android framework. The Geocoder query methods will return an empty list if there no backend service in the platform (http://developer.android.com/reference/android/location/Geocoder.html)
[update]
So after nights of research, I can't seems to make it work - Google simply wont give me the result. Some discussion on android-developers points a fact that getFromBusinessName was omitted when Google Navigation came out. So I'm starting to assume that Google is pulling back some of their geocoding service.
I can always create a webpage that use Google Geocoder API, but its limited to 2500 api call - and I dont think it will be legal (lol). So what are my alternatives here?

I want to search for GPS locations for with Google Maps. I have already registered with Google Maps API, and got the key. I can successfully pinpoint my current location on a map. The next part is to search for items around the current GPS location.
Approach 1: I tried using Android's geocoder.getFromLocationName("UPS",5) but I am not getting anything.
Approach 2: hit Google https://maps.googleapis.cm/maps/apo/place/search but it needs a client id. To get a client id I have to create a premier account. Do I have to do all this?

I'm using the android.location.Geocoder for the first time. The Idea is: I have a Listener on a button which takes input from an EditText and resolve the location. Up to now it's debugging phase, so I have no handler taking messages from the thread, only geocoding and write to logcat.
Q: Why this method always returns an empty list of Address objects?
CODE:...............
Somebody knows why? (btw I am using 1.6 sdk) Input tried

I have recently noticed that when Running the function geoCoder.getFromLocationName() on android 2.2 (Froyo) then i Receive a IOExeption (Which does not occur on other SDK versions).
After some reserch i have found suggentions to add the following Permisions:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
However this does not solve the problem, and this appears to be a Android SDK Bug.
Is there a knows solution to this problem?
Here is the stack trace though it is not particularly helpful the inner stack trace is null so not great.

I have two problem regarding Location API for SDK 1.5
1) I have developed a location based application for SDK 1.0.
I have used Geocoder to get the location data. Its working fine on SDK 1.0 emulator and its supported devices.
Today I downloaded SDK 1.5, and tried to run the same app. But the Geocoder didn't give any result. I am getting
Geocoder.getFromLocation(loc.getLatitude(), loc.getLongitude(), 1) as null.
2) LocationManager.removeUpdates(location_listener) is not removed (I mean still the GPS icon is visible on emulator).
But the same worked fine on SDK 1.0.

The documentation states : The Geocoder class requires a backend service that is not included in the core android framework, how/where can I obtain such a service?

My calls to getFromLocationName() always fail the "first" time I start my app. I catch the IOException which has reason:
Unable to parse response from server
Then I make a second call and it succeeds. Once things are "awake" all future calls to getFromLocationName() succeed, it's just that first one, and there is a ton of latency.
I haven't run this on a device yet, just in the emulator. This seems like a network problem, but it is so reproducible I'm thinking I'm not initializing something properly. I'm using Android SDK 1.1.

I have a problem getting the Geocoder to return results on my new PC during development. I started writing a android app on my other (Win XP) system and Geocoder worked fine and returned locations based on an address that I passed to it.
I recently bought a new PC (Win 7). Moved the code over to it and now the no address queries return any results. I tried a couple that did work on the xp machine, but are returning no results on the new pc. It does not give any errors.
I did generate a keyfile on the old pc. Do i need to create another on the new pc? Does the Geocoder require the key? It is not from the maps api.

I am having a real hard time with the geocoder API of android sdk 1.5rc2. In my app I am trying to get the addresses corresponding to a location name by using the getFromLocationName method of the Geocoder class. But the problem is whenever I call this method it returns a null value. I have also pushed a geodb file containing some fake addresses at 'data/misc/location' directory in the phone.
The format of the data in the geodb file is as follows :
address 1 latitude "38.898763" longitude "-77.036655" line 0 "1600 Pennsylvania Ave NW" line 1 "Washington, DC 20006" locality "Washington" region "DC" postalCode "20006" countryCode "US" countryName "United States"
and following is the code snippet : Geocoder geocoder = new Geocoder(this, Locale.getDefault()); List<Address> addresses=geocoder.getFromLocationName("1600 Pennsylvania", 10);

My application that uses geocoding was working fine till last week and now all of a sudden am not getting proper data from the same.
I used getLocality() , which was returning CITY name previously. But now it is returning NULL.
Is something changed? or Has someone faced the same issue?
My application is on SDK 1.0

I was reading the documentation regarding the Geocoder class and the description says:
"The Geocoder class requires a backend service that is not included in the core android framework."
I assume this means that the proprietary Google Maps API's provides this backend service which routes through the Google Maps service. I searched around trying to find information on constructing my own Geocoder backend service but have come up nil. Is there any way to produce a custom backend for the Geocoder class?
If it helps formulate a better response I'm trying to determine locations based on the GPS coordinates to produce areas such as streets, cities, parks, shopping centers, etc. If something like this already exists then I'd be more than happy to use it, but from what I've seen searching around no such service exists for an Android application.

In my application, we allow users to add locations. So far, we have been using the Geocoder class to let users search for different locations. For the most part, this works quite well. However, there are some issues we have been running into and I'm not sure what we can do to fix them.
Some searches (such as "moscow") return nothing when I feel you should definitely be getting a result for this. Other searches (such as "que") give very poor results and not the ones you would expect. However, if I use the Google maps application and run these same searches, I get results as I would expect.
I would really like my app to give search results like the maps application! My guess is that since the maps application is developed by Google, they are using some search functionality not available to the rest of us developers. Unless I'm missing something?
How to get better search results?

I'm having a problem calling GeoCoder.getFromLocation();
I have a LocationListener calling an updateLocation() method in my class, which in turns calls GeoCoder.getFromLocation() with the current location.
CODE:............
When I run this code on a device (HTC Magic 1.6) I get the following error :
D/LocationMasfClient(15392): getAddressFromProtoBuf(): Ignore feature 0,1er Arrondissement Paris D/AndroidRuntime(21403): Shutting down VM W/dalvikvm(21403): threadid=3: thread exiting with uncaught exception (group=0x4001da38) E/AndroidRuntime(21403): Uncaught handler: thread main exiting due to uncaught exception
If I run the same code on an emulator (1.6 with google api) the error I get is :
D/GpsLocationProvider(52): setMinTime 0 E/LocationMasfClient(52): reverseGeocode(): no feature in GLocation

I am trying to run the example as given in the book Professional Android Development by Reto Meier[pg 220], but i am not able to get the address string i always get "No address" . I read about the same prob in this forum, and i tried it in api level 7 but in both 7 and 8 api levels , i am getting the same output, i.e. No address. Also can anyone please tell me that here i have to manually supply the lat and longitude , so it is it possible that to get them automatically?

I am able to successfully get lat/long and pass it to the geocoder to get an Address. However, I don't always get an address back. Seems like it takes a couple of attempts? I'm not sure why.
Is there a better way for me to obtain the address at this point?

I am calling this method here:

I find that geocoder apis particularly getFromLocation using Lat and Lnt is not very reliable. I am noticing this behavior more after I upgraded to android 2.2 on my Droid. I get an invalid argument exception for Latitude. The funny thing it is not consistent in this behavior.

I'm trying to use the GeoCoder to get the lat/lon for a couple of addresses. I'm running into an error where the address list comes back empty sometimes. It seems to be completely random. I have a start point and an end point to draw and route. Sometimes I can't get either one, sometimes I can get the start but not the end, sometimes I can get the end but not the start. I never seem to be able to get both. Not sure why. Yesterday it worked fine.

I do not get any results from the Geocoder in the 1.5 preview release. Any information on this? In the maps application it works but my calls simply return an empty list (no exception, all permissions I know of (in this case only Internet) are set.

I'm using the geocoder in the android map api, this work relatively good, my problem though is that i want to be able to get a number of addresses near a geopoint ! I thought about calculating different geopoint near the a center geopoint, but what about the cost of calling the reverse geocoder multiple times etc.

I am developing a maps application and want to search for business points like pizza hut etc as done by native android maps application. I am using getfromlocationname() API for this purpose. But i am not able to get any result for any business search. But when i search using native maps application it shows results on native maps application. May I know the reason of this behaviour of getfromlocationname() API , or do i need to use some thing different for business search. I am working on SDK 1.0.

According to the Geocoder documentation, the class provides methods into a backend service which may or may not exist on the device. If the geocoder doesn't exist on the device, theoretically a geocode request will return no results. However, how can one differentiate between no results due to there being no backend geocoder service vs. there being no results because the location makes no sense? My app already requires the Google Maps API, so perhaps this is a moot point; as a secondary question, does the Google Maps API always include a Geocoder?

I can [specify a square][1] where the Geocoder shall search in, but I found no way to specify a certain country. Unfortunately, my country isn't quadrangular ;( What should I do? Use another reverse geocoding service?
I'd want to build a search box where the user can search for a city (with auto suggestion). On every keystroke the current search query is going to be delivered to the Geocoder.

I am using the Geocoder.getFromLocation(lat,lon,1) and it seems that a lot of the time nothing gets returned to the List<Address> array sometimes it works as it is suppose to. Is there a better way to get the city/state from the lat/lon that is more reliable? the code I use is below:

When it doesn't work it is because addresses is null

I'm trying to open a dialog window, but every time I try to open it it throws this exception:
CODE:.................
I'm creating it by calling showDialog with the display's id. The onCreateDialog handler logs fine and I can step through it without an issue, but I've attached it since it seems like I'm missing something:
CODE:............
Is there something missing from this? Some questions have talked about having this problem when creating a dialog from onCreate, which happen because the activity isn't created yet, but this is coming from a call from a menu object, and the appContext variable seems like it is correctly populated in the debugger.
