I want to get the current location for android with out using Google APIs Key that's why
I'm Using the Geocoder.
It is working absolutely for many devices but it not for some selected devices like Latest android version_12 and in OnePlus_v10,11,12.
if (Geocoder.isPresent())
{
try
{
Geocoder geocoder = new Geocoder(contex, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);
if (addresses.size() > 0)
{
cityName = addresses.get(0).getAddressLine(0);
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
Please provide the solution for the same share with someone you know who can fix it.
Also is there any changes in new android device regarding GPS,WI-FI, Network Checker.
I am trying to get locations from the string which is being searched. But, in some cases addressList is returning size 0(i.e. H.M. education centre, kolkata). I don't have latitude and longitude to search the place. Needed help.
String addressString = (String) adapterView.getItemAtPosition(position);
String addressString1 = (String) adapterView.getItemAtPosition(position);
List<Address> addressList = null;
Address address = null;
if (!TextUtils.isEmpty(addressString))
{
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
try
{
addressList = geocoder.getFromLocationName(addressString, 1);
}
catch (IOException e)
{
e.printStackTrace();
addressString = addressString1;
}
//noinspection ConstantConditions
if(addressList != null && addressList.size() > 0)
{
address = addressList.get(0);
}
}
As alternative you can use Geocoding API or Places API web services. I checked your address 'H.M. education centre, kolkata' in Geocoding API web service request and figured out that coordinate can be found. Have a look at Geocoder tool with this address:
https://google-developers.appspot.com/maps/documentation/utils/geocoder/#q%3DH.M.%2520education%2520centre%252C%2520kolkata
In your Java code I can suggest using the Java Client for Google Maps Services hosted at Github:
https://github.com/googlemaps/google-maps-services-java
The code snippet to execute web service request with this client library is the following
GeoApiContext context = new GeoApiContext.Builder()
.apiKey("AIza...")
.build();
GeocodingResult[] results = GeocodingApi.geocode(context,
"H.M. education centre, kolkata").await();
The Javadoc for the current version of the library can be found at
https://googlemaps.github.io/google-maps-services-java/v0.2.7/javadoc/
Note also that places like this one can be found via Places API web service. In this case the code snippet will be
GeoApiContext context = new GeoApiContext.Builder()
.apiKey("AIza...")
.build();
TextSearchRequest req = PlacesApi.textSearchQuery(context, "H.M. education centre, kolkata");
try {
PlacesSearchResponse resp = req.await();
if (resp.results != null && resp.results.length > 0) {
//Process your results here
}
} catch(Exception e) {
Log.e(TAG, "Error getting places", e);
}
I hope this helps!
I am using google's geocoder class to fetch city with given lat-long.
I am facing this problem in India where earlier city name was Banglore and now it is changed to bengaluru.
So when I fetch using geocoder.getFromLocation method I get Banglore instead of bengaluru
While using the same lat-long I call Geocoder api directly, then I get the right city value i.e bengaluru.
Following is code geocoder class code
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
String city = null;
if (geocoder != null) {
if (geocoder.isPresent()) {
try {
List<Address> addressList = geocoder.getFromLocation(params[0], params[1], 1);
city = addressList.get(0).getLocality();
} catch (Exception e) {
e.printStackTrace();
}
}
}
My target and compile sdk version is 23.
Thank you in advance.
I have created simple code just for getting address from string location. Code brakes at starred line. Why ?? if I print the exception : Service not Available
List<Address> address;
String myAddress = "Vilnius";
Geocoder coder = new Geocoder(getApplicationContext(), Locale.getDefault());
System.out.println("coder : :" + coder);
**address = coder.getFromLocationName(myAddress, 1);**
ObjLoc1adr = coder.getFromLocationName(ObjLoc1String, 1);
ObjLoc2adr = coder.getFromLocationName(ObjLoc2String, 1);
Because of this you should always wrap that code in a try block to catch an IOException. There is no guarantee that the Geocoder always find a location or the service is reachable. This hasn't to be a fault of your code or device. A simple connection problem or timeout is enough to brake your App.
To be save have something like this:
if(GeoCoder.isPresent()) {
Geocoder geocoder = new Geocoder(this);
String myAddress = "Vilnius";
List<Address> addresses = null;
try {
address = geocoder.getFromLocationName(myAddress, 1);
if (!addresses.isEmpty()) {
Address address = list.get(0);
// do something with your address
} else {
// No results for your location
}
} catch (IOException e) {
e.printStackTrace();
}
}
I am trying to get an address based on the long/lat. it appears that something like this should work?
Geocoder myLocation = Geocoder(Locale.getDefault());
List myList = myLocation.getFromLocation(latPoint,lngPoint,1);
The issue is that I keep getting : The method Geocoder(Locale) is undefined for the type savemaplocation
Any assistance would be helpful. Thank you.
Thanks, I tried the context, locale one first, and that failed and was looking at some of the other constructors (I had seen one that had mentioned just locale). Regardless,
It did not work, as I am still getting : The method Geocoder(Context, Locale) is undefined for the type savemaplocation
I do have : import android.location.Geocoder;
The following code snippet is doing it for me (lat and lng are doubles declared above this bit):
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
Here is a full example code using a Thread and a Handler to get the Geocoder answer without blocking the UI.
Geocoder call procedure, can be located in a Helper class
public static void getAddressFromLocation(
final Location location, final Context context, final Handler handler) {
Thread thread = new Thread() {
#Override public void run() {
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
String result = null;
try {
List<Address> list = geocoder.getFromLocation(
location.getLatitude(), location.getLongitude(), 1);
if (list != null && list.size() > 0) {
Address address = list.get(0);
// sending back first address line and locality
result = address.getAddressLine(0) + ", " + address.getLocality();
}
} catch (IOException e) {
Log.e(TAG, "Impossible to connect to Geocoder", e);
} finally {
Message msg = Message.obtain();
msg.setTarget(handler);
if (result != null) {
msg.what = 1;
Bundle bundle = new Bundle();
bundle.putString("address", result);
msg.setData(bundle);
} else
msg.what = 0;
msg.sendToTarget();
}
}
};
thread.start();
}
Here is the call to this Geocoder procedure in your UI Activity:
getAddressFromLocation(mLastKownLocation, this, new GeocoderHandler());
And the handler to show the results in your UI:
private class GeocoderHandler extends Handler {
#Override
public void handleMessage(Message message) {
String result;
switch (message.what) {
case 1:
Bundle bundle = message.getData();
result = bundle.getString("address");
break;
default:
result = null;
}
// replace by what you need to do
myLabel.setText(result);
}
}
Don't forget to put the following permission in your Manifest.xml
<uses-permission android:name="android.permission.INTERNET" />
It looks like there's two things happening here.
1) You've missed the new keyword from before calling the constructor.
2) The parameter you're passing in to the Geocoder constructor is incorrect. You're passing in a Locale where it's expecting a Context.
There are two Geocoder constructors, both of which require a Context, and one also taking a Locale:
Geocoder(Context context, Locale locale)
Geocoder(Context context)
Solution
Modify your code to pass in a valid Context and include new and you should be good to go.
Geocoder myLocation = new Geocoder(getApplicationContext(), Locale.getDefault());
List<Address> myList = myLocation.getFromLocation(latPoint, lngPoint, 1);
Note
If you're still having problems it may be a permissioning issue. Geocoding implicitly uses the Internet to perform the lookups, so your application will require an INTERNET uses-permission tag in your manifest.
Add the following uses-permission node within the manifest node of your manifest.
<uses-permission android:name="android.permission.INTERNET" />
The reason for this is the non-existent Backend Service:
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.
First get Latitude and Longitude using Location and LocationManager class. Now try the code below for Get the city,address info
double latitude = location.getLatitude();
double longitude = location.getLongitude();
Geocoder gc = new Geocoder(this, Locale.getDefault());
try {
List<Address> addresses = gc.getFromLocation(lat, lng, 1);
StringBuilder sb = new StringBuilder();
if (addresses.size() > 0) {
Address address = addresses.get(0);
for (int i = 0; i < address.getMaxAddressLineIndex(); i++)
sb.append(address.getAddressLine(i)).append("\n");
sb.append(address.getLocality()).append("\n");
sb.append(address.getPostalCode()).append("\n");
sb.append(address.getCountryName());
}
City info is now in sb. Now convert the sb to String (using sb.toString() ).
Well, I am still stumped. So here is more code.
Before I leave my map, I call SaveLocation(myMapView,myMapController); This is what ends up calling my geocoding information.
But since getFromLocation can throw an IOException, I had to do the following to call SaveLocation
try
{
SaveLocation(myMapView,myMapController);
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
Then I have to change SaveLocation by saying it throws IOExceptions :
public void SaveLocation(MapView mv, MapController mc) throws IOException{
//I do this :
Geocoder myLocation = new Geocoder(getApplicationContext(), Locale.getDefault());
List myList = myLocation.getFromLocation(latPoint, lngPoint, 1);
//...
}
And it crashes every time.
Use this
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
