Android :: Reverse Geocoder - GetFromLocation - Lat - Lnt

Nov 2, 2010

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.

Android :: Calling GeoCoder GetFromLocation

Mar 23, 2010

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

Nov 4, 2009

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.

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?

Android :: GeoCoder Is Not Working In SDK 1.5

May 15, 2009

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.

Android :: Geocoder No Longer Works On New PC

Feb 16, 2010

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.

Android :: IOException On Geocoder.getFromLocationName

Jul 29, 2010

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?

Android :: Geocoder API - Returns A Null Value

Aug 26, 2009

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);

Android :: Geocoder Backend Service

Jun 17, 2009

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.

Android :: Geocoder And Location Search

Jul 8, 2010

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?

Android :: Geocoder Doesn't Always Return A Value

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?

Android :: GeoCoder To Get The Lat/lon For A Couple Of Addresses

Sep 9, 2010

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.

Android :: Geocoder GetFromLocationName Is Not Finding Address

Jul 20, 2010

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?

Android :: Google Maps API And Geocoder.getFromLocationName

Oct 29, 2010

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?

Android :: Why Geocoder.getFromLocationName - Returns An Empty List

May 19, 2010

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?

Android :: GeoCoder.getFromLocationName Throws IO Exeption In Froyo

Aug 26, 2010

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.

Android :: Reverse Geocoding In App

Oct 17, 2010

I am trying to Reverse GeoCode current Lat/Long data to just Admin Area and Sub Admin Area using the Geocoder class.

I am using the NETWORK_PROVIDER as the Location provider. Here is the code that I use and it works. The problem is sometimes it does not give me any location sometimes it does.

Android Manifest permissions I am using.

CODE:.............

Here is the rest of the code that does give me correct location from time to time but nothing at other times.

CODE:..............

Are there restrictions with the network providers how frequently you can request location data?

How can I make sure that everytime its run this can give me valid location data.

Thanks in advance for any insight into this.

PS: I have run this code on my real device running Froyo 2.2 (Verizon Wireless). Target API Level 8.

This is what I got from my debugging.

Latitude Longitude is always fetched but the getFromLocation often returns null for the latitude longitude data passed to it. So what should be the workaround? May be pass the Lat/Long info to Google Maps API for reverse geocoding. Will be glad to receive any input.

Android :: Reverse Tether

Mar 24, 2010

I have a G1 and I now have an app named MapDroid BUT so slow to download the maps. If I could hook up my G1 to a computer at the internet cafe that has a ASDL connection it would go much faster AND I would be able to do something else beside watch the yellow bar slooooooowly move. I am not in the USA. One guy said the best way is buy a Bluetooth drive that looks like a flash drive. Plug it in the PC and my G1 should get internet. Not sure. I think files would work but not sure about internet. If the cable won't work then why should bluetooth?

Android :: StartLayoutAnimation In Reverse Order

Aug 18, 2010

IŽm doing a layout animation on my listview where I fade the list elements into view using a LayoutAnimation with android:animationOrder="normal". It works perfectly fine and the elements are faded into view in top-to-bottom order. However, if I trigger a layout animation twice (eg call startLayoutAnimation before the list view has finished animating its views), the listview performs the new layout animation in reverse order; bottom-to-top.

Android :: Reverse Desktop Tether

Oct 12, 2010

I just got my first Android and love it after having used Win Mobile for years. However, there's one app I just can't seem to find.

I want something like MyMobiler (Windows Mobile - My Mobile)

Instead of accessing my PC desktop on my phone, I was able to FULLY access my phone desktop on my pc (i.e., I could completely operate my phone on my PC which allowed me to type and enter data faster and more accurately).

Does anyone know an app that'll do this (even a non-free app would be great).
I had grown so accustomed to using this application that I will now be lost if I can't find a suitable replacement.

Android :: Reverse Tether Via Bluetooth PAN

Oct 12, 2010

We've been trying to reverse tether (using a SmartQ V5, android version 2.1) to another device that has an Internet connection we want to share. That is to say, the Android device is the client and needs to get access to the Internet through connecting to a Bluetooth PAN network.

We have so far been able to get root access on android, but have had no luck with bluetooth PAN. We found that bluetooth PAN isn't compiled natively in android (at least not in 2.1 or before), and to enable it you'd need to turn them on and compile the OS image yourself. Does this concur with others' understanding?

Has anyone had any luck in compiling an android OS or setting up PAN to do reverse-tethering with another device (say PC)?
