Why is Android Geocoder throwing a “Service not Available” exception?

阅读更多关于 Why is Android Geocoder throwing a “Service not Available” exception?

The app uses the Geocoder object. It works fine on my stock Froyo Nexus One. But then I run the exact same app on a different device (an Advent Vega 10" tablet also running Froyo) and I get this exception: Service not Available . The method I'm using is getFromLocationName() , I'm building against the Android 1.6 Google API. I'm aware of an issue where this exception is thrown on the emulator, but I suspect this is different. Why would it be thrown on one device running Froyo but not another? The app is a location app, and as the tablet has no GPS or mobile network, in a scenario where the Wi

问题 I basically want to retrieve a list of city and state within a zipcode. Is Google\'s Geocode API capable of doing so?

Thanks EDIT: I was able to retrieve the City and State through: http://maps.google.com/maps/geo?output=xml&q=14606 but is there a limitation against that? 回答1: Use the GeoCoding API For

问题 Is there a fast way to convert latitude and longitude coordinates to State codes in R? I\'ve been using the zipcode package as a look up table but it\'s too slow when I\'m querying lots of lat/long values If not in R is there any way to do this using google geocoder or any other type of fast querying service? Thanks! 回答1: Here is a function that takes a data.frame of lat-longs within the lower 48 states, and for each point, returns the state in which it is located. Most of the function simply

阅读更多关于 Service not available while calling geoCoder.getFromLocation()

问题 I know sometimes google back-end service might not be available. Hence a solution might be to loop until i get the data. private class getLocationDetails extends AsyncTask<String, Void, String> { @Override protected String doInBackground(String... params) { Log.d(\"looping\", \"\" + count + \"\"); count++; double lat = Double.parseDouble(params[0]); double lng = Double.parseDouble(params[1]); List<Address> addresses = null; try { Geocoder gCoder = new Geocoder(ImageAndLocationActivity.this,

How do I get the latitude and longitude of an address using the Google Maps API? 回答1: public GeoPoint getLocationFromAddress(String strAddress){ Geocoder coder = new Geocoder(this); List<Address> address; GeoPoint p1 = null; try { address = coder.getFromLocationName(strAddress,5); if (address==null) { return null; } Address location=address.get(0); location.getLatitude(); location.getLongitude(); p1 = new GeoPoint((double) (location
