Android :: How Can Tell When An Android Device Has Geocoder Backend Service
Feb 12, 2010
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 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.
I'm really hoping someone here has seen something like this. I'm essentially looking for a notepad app for the Android. But there is a trick to this. I want the notes to be saved and synced as accessible documents on GoogleDocs so that I can edit them on my Mac. On the Android, this should be a simple notebook / notepad app.
I would like to write a client application for Android that uses the Google App Engine as a database backend. My Android client would connect to the App Engine to save information, then it would connect later for reports. Is it possible to use the App Engine as a backend like this?
my application objective is to save location updates every ,let say, 20 minuets .I used service and it worked fine , but when i lock the screen or it is locked automatically the service stop running .when i unlock it , service runs again.How to make my code run all the time in all conditions?
I am looking to implement an Android service that will serve as the "driver/hardware access" for a device that will connect to the usb host port. Is there a good framework or example showing how I can make a service interact with this device? Its not a standard device that Android already supports other than the fact it connects via usb.
I am able to do this with linux libusb native code already but what would be the pathway to make this work through the android java framework?
I want to avoid having to make a kernel level driver for this that is why I prefer to have this implemented as a service for other apps to access the device.
I have a set of mp3 files on my computer which i want to be the server. Now i have a web service(Songs_Collection). This web service returns the list of all songs present on the server to the user.The user can download the desired file directly from the server.
I have a small problem :
How does my web service get the list of audio files kept on the server in the folder c:Audio Files.
Someone suggested that i need to keep the names in a "Web Content" folder, but can anyone suggest how should i approach it?
I worked out on this part . But now how do I send it to the client on device ?
Can i send it directly as an array? I guess then some seriliazation-deserialization needs to be done. Or If send it as an XML file then how should I proceed? (This is more important)
I have written a class which extends the Service class of android and would like to launch the service during device boot-up. From the service I would like to receive the intents such as boot completed and screen off and on. Currently I am using a BroadcastReceiver to get the boot completed intent and then on starting a service to receive screen on and off intents. But I would like to remove either the broadcast receiver or the service. Any inputs.
I've read the posts that state that there is no way to automatically start a service right after the package is installed. In my case, i have two apps- one runs as a service and collects data, the other displays it. the second app has the Activity which can be used to start the service. in order to provide the most accurate information, the service must be started immediately after installation. however, if the user decides not to run the activity immediately, then there would be a gap between the time the service is installed, versus when it gets started. of course, asking user to reboot after installation is one option, but not a great user experience. Any suggestions on how to achieve this?
If someone clicks on the link from an android device, then the link opens in the market. If they click from their computer, then it offers to send them a link by email (so they can click on the link on their device).
the download emails have a (subtle) advert for my app, but the feature is clearly your app!
I have coded this service, that computes stuff and i want other applications to be able to bind this service, i.e. i want to enable other programmers to communicate with this service. problem is, this has to work without these other programmers to get access to the source code. just the (installed) apk with the remote service is given (and of course a detailed description of the service' interface)...problem is, eclipse keeps braggin' about that the packages of the service are not available in source code...
I have a background service component which is reacting to changes in network connectivity. I would like to alert the user that a a connectivity change event has occurred by popping up a Toast View on the device screen. Is this possible ? Can it be done even though a Service component does not have a UI associated with it ?
I'm looking for a protocol to secure a connection between a mobile device and a web service. I want to ensure that only the mobile device can perform actions on the web service and vice versa. Data doesn't need to be encrypted. I know Oauth, but it seems that it's more used to secure connections when you got 3 different entities (Server, Consumer and Auth). Here, the Consumer and the User would be the same person. Is there a simple protocol to do that (without requiring the user to login and then authorize the access token like it is the case for Oauth)? I need to use it on different plateforms, so the protocol needs to be available at least on iPhone and PHP.
I need test my Android app on a Motorola Cliq but don't have one. Is there a testing service that will let me make a debug connection to that device so I can run some tests and find out where the code is failing. Video connections won't tell me that.
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 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 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.
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);
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?
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.
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?
