I am working on an android map app.I am getting direction from latitude and longitude.
But the problem is this i want to update map directions after some time or after location change.
My code is below can any one help me in this.
Button.OnClickListener addressclick = new Button.OnClickListener(){
#Override
public void onClick(View v) {
/*TextView tv = (TextView)v;
String latitude ="0";
String longitude = "0";
String label = "Location";
String uriBegin = "geo:" + latitude + "," + longitude;
String query = tv.getText().toString() + "(" + label + ")";
String encodedQuery = Uri.encode(query);
String uriString = uriBegin + "?q=" + encodedQuery+"&z=10";
Uri uri = Uri.parse(uriString);
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
startActivity(intent);*/
TextView tv = (TextView)v;
String addressStr = tv.getText().toString();
Geocoder geoCoder = new Geocoder(context);
try {
List<Address> addresses =
geoCoder.getFromLocationName(addressStr, 1);
if (addresses.size() > 0) {
latitude = addresses.get(0).getLatitude();
longitude =addresses.get(0).getLongitude(); }
} catch (IOException e) { // TODO Auto-generated catch block
e.printStackTrace();
}
String directionweburl = "http://maps.google.com/maps?daddr="+Double.toString(latitude)+","+Double.toString(longitude)+"&saddr="+Double.toString(currentlat)+","+Double.toString(currentlong);
Intent myIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(directionweburl));
myIntent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
startActivity(myIntent);
}
};
what am i missing here?anyone can tell?
I think you should start a service and put regular check in it. After some time, you can update map directions or check current location in order to update location info.

I am trying to get location name or address. I have successfully fetched the latitude and longitude by Google Fused Location API.
Now I want to fetch the location address (example : City name,Road no, or specific address) by using the latitude and longitude.
For this purpose I am using Google Geocoder and it works fine. But in some devices the location address returns the null value.
I searched in the net for the solution of this problem and found that some device manufacturers does not include this feature in their devices. That's why those device can't find the the address by Reverse Geocoding method. Here is the link of that information
So is there any alternative way to find the address name as string without Geoconding ?
Here is my code for fetching address by Geocoding
public static void getAddress(Context context, double LATITUDE, double LONGITUDE) {
try {
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
if (addresses != null && addresses.size() > 0) {
String address = addresses.get(0).getAddressLine(0); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()
String city = addresses.get(0).getLocality();
String state = addresses.get(0).getAdminArea();
String country = addresses.get(0).getCountryName();
String postalCode = addresses.get(0).getPostalCode();
String knownName = addresses.get(0).getFeatureName(); // Only if available else return NULL
Log.d(TAG, "getAddress: address" + address);
Log.d(TAG, "getAddress: city" + city);
Log.d(TAG, "getAddress: state" + state);
Log.d(TAG, "getAddress: postalCode" + postalCode);
Log.d(TAG, "getAddress: knownName" + knownName);
}
} catch (IOException e) {
e.printStackTrace();
}
return;
}
Use this its working for me
public class LocationAddress {
private static final String TAG = "LocationAddress";
private static String area = null;
public static void getAddressFromLocation(final double latitude, final double longitude,
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> addressList = geocoder.getFromLocation(
latitude, longitude, 1);
if (addressList != null && addressList.size() > 0) {
Address address = addressList.get(0);
StringBuilder sb = new StringBuilder();
for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
sb.append(address.getAddressLine(i)).append("\n");
}
area = address.getSubLocality();
sb.append(address.getLocality()).append("\n");
sb.append(address.getPostalCode()).append("\n");
sb.append(address.getCountryName());
result = sb.toString();
}
} catch (IOException e) {
Log.e(TAG, "Unable connect to Geocoder", e);
} finally {
Message message = Message.obtain();
message.setTarget(handler);
if (result != null) {
message.what = 1;
Bundle bundle = new Bundle();
/*result = "Latitude: " + latitude + " Longitude: " + longitude +
"\n\nAddress:\n" + result;*/
bundle.putString("address", result);
bundle.putString("area",area);
message.setData(bundle);
} else {
message.what = 1;
Bundle bundle = new Bundle();
/* result = "Latitude: " + latitude + " Longitude: " + longitude +
"\n Unable to get address for this lat-long.";*/
bundle.putString("address", result);
bundle.putString("area",area);
message.setData(bundle);
}
message.sendToTarget();
}
}
};
thread.start();
}
}
To call this in your Activity use
LocationAddress locationAddress = new LocationAddress();
locationAddress.getAddressFromLocation(latitude,longitude,
getApplicationContext(), new GeocoderHandler());
GeocoderHandler
private class GeocoderHandler extends Handler {
#Override
public void handleMessage(Message message) {
String locationAddress = null;
String area = null;
switch (message.what) {
case 1:
Bundle bundle = message.getData();
locationAddress = bundle.getString("address");
area = bundle.getString("area");
break;
default:
locationAddress = null;
}
if(locationAddress != null)
locationAddress=locationAddress.replaceAll("[\r\n]+", " ");
Log.d("===========>>>",area);
Log.d("===========>>>>",locationAddress);
}
}
I have found this solution: here to get the location name but I don't know how to display it in my textView:
LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
String provider = locationManager.getBestProvider(new Criteria(), true);
Location locations = locationManager.getLastKnownLocation(provider);
List<String> providerList = locationManager.getAllProviders();
if(null!=locations && null!=providerList && providerList.size()>0){
double longitude = locations.getLongitude();
double latitude = locations.getLatitude();
Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.getDefault());
try {
List<Address> listAddresses = geocoder.getFromLocation(latitude, longitude, 1);
if(null!=listAddresses&&listAddresses.size()>0){
String _Location = listAddresses.get(0).getAddressLine(0);
}
} catch (IOException e) {
e.printStackTrace();
t.append("\n " + ????? + " ");
}
}
The t is the textView
You have the name address in the String _Location. Therefore, you could set the value of TextView in the try block.
try {
List<Address> listAddresses = geocoder.getFromLocation(latitude, longitude, 1);
if(null!=listAddresses&&listAddresses.size()>0){
String _Location = listAddresses.get(0).getAddressLine(0);
}
t.setText(_Location);
}
Further Infomation
String address1 = listAddresses.get(0).getAddressLine(0);
String city = listAddresses.get(0).getLocality();
String state = listAddresses.get(0).getAdminArea();
String country = listAddresses.get(0).getCountryName();
String postalCode = listAddresses.get(0).getPostalCode();
String knownName = listAddresses.get(0).getFeatureName();
t.setText(address1 + " " + city + "\n" + state + " " + postalCode);
You could use this code to get further information about the adress
I have a requirement that whenever I drag/browse the Google map and place a marker on it, it should display the name of the place(where the marker is placed) in an AutocompleteTextview. I have checked out the Places API and the Geocoder class but i least understood it. I need to do the task same as that of the Places tab in the life360 app. How can I achieve it?
try this it may help you...
When u mark a place, try to capture latitude & longitude with marker & use this code to get location name
public String getAddress(Context context, double lat, double lng) {
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
try {
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
Address obj = addresses.get(0);
String add = obj.getAddressLine(0);
add = add + "\n" + obj.getCountryName();
add = add + "\n" + obj.getCountryCode();
add = add + "\n" + obj.getAdminArea();
add = add + "\n" + obj.getPostalCode();
add = add + "\n" + obj.getSubAdminArea();
add = add + "\n" + obj.getLocality();
add = add + "\n" + obj.getSubThoroughfare();
return add;
} catch (IOException e) {
e.printStackTrace();
Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
return null;
}
}
Try this I hope Its work.
public void getLocation(double lat, double lng) {
Geocoder geocoder = new Geocoder(MapsActivity.this, Locale.getDefault());
try {
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
Address obj = addresses.get(0);
String add = obj.getAddressLine(0);
Log.e("IGA", "Address" + add);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
i want to passing variable latitude longitude to google map direction?
can help me see the error or have a new solution?
this is my java code :
public void onClickShowMap(View v) {
String latitude = ((TextView) findViewById(R.id.latitude)).getText().toString();
String longitude = ((TextView) findViewById(R.id.longitude)).getText().toString();
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?f=d&daddr="+latitude+","+longitude));
startActivity(intent);
}
Use this code,
final Intent intent = new Intent(Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?" + "saddr=" + lat
+ "," + lon + "&daddr=" + lattitude + ","
+longitude));
intent.setClassName("com.google.android.apps.maps",
"com.google.android.maps.MapsActivity");
((Activity) this).startActivity(intent);
What i have: currently my app is only telling me the coordinates of my current location.
What i want: Get location name from coordinates fetched by gps, so that i could know where exactly i am. (Name of location)
Here is complete code from fetching long - lat to getting address:
LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
String provider = locationManager.getBestProvider(new Criteria(), true);
Location locations = locationManager.getLastKnownLocation(provider);
List<String> providerList = locationManager.getAllProviders();
if(null!=locations && null!=providerList && providerList.size()>0){
double longitude = locations.getLongitude();
double latitude = locations.getLatitude();
Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.getDefault());
try {
List<Address> listAddresses = geocoder.getFromLocation(latitude, longitude, 1);
if(null!=listAddresses&&listAddresses.size()>0){
String _Location = listAddresses.get(0).getAddressLine(0);
}
} catch (IOException e) {
e.printStackTrace();
}
}
You can us the GeoCoder which is available in android.location.Geocoder package. The JavaDocs gives u full explaination. The possible sample for u.
List<Address> list = geoCoder.getFromLocation(location
.getLatitude(), location.getLongitude(), 1);
if (list != null & list.size() > 0) {
Address address = list.get(0);
result = address.getLocality();
return result;
The result will return the name of the location.
Here i am given a single just pass the latitude and longitude in this function then you got all the information related to this latitude and longitude.
public void getAddress(double lat, double lng) {
Geocoder geocoder = new Geocoder(HomeActivity.mContext, Locale.getDefault());
try {
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
Address obj = addresses.get(0);
String add = obj.getAddressLine(0);
GUIStatics.currentAddress = obj.getSubAdminArea() + ","
+ obj.getAdminArea();
GUIStatics.latitude = obj.getLatitude();
GUIStatics.longitude = obj.getLongitude();
GUIStatics.currentCity= obj.getSubAdminArea();
GUIStatics.currentState= obj.getAdminArea();
add = add + "\n" + obj.getCountryName();
add = add + "\n" + obj.getCountryCode();
add = add + "\n" + obj.getAdminArea();
add = add + "\n" + obj.getPostalCode();
add = add + "\n" + obj.getSubAdminArea();
add = add + "\n" + obj.getLocality();
add = add + "\n" + obj.getSubThoroughfare();
Log.v("IGA", "Address" + add);
// Toast.makeText(this, "Address=>" + add,
// Toast.LENGTH_SHORT).show();
// TennisAppActivity.showDialog(add);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
I hope you get the solution to your answer.
