android-How to check location is in special area?

I want to use google map in my android app in specific area. for example in special country. How can I check that my current location is in that place?
updates:
for example how to check that I am in New Delhi city

You can try using LatLngBounds and LatLngBounds.contains()
private LatLngBounds NewDelhi = new LatLngBounds(your special area SE LatLng , NE LatLng );
if(NewDelhi.contains(your location LatLng))
//Do something

Get city name from Location:
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(myLocation.getLatitude(), myLocation.getLongitude(), 1);
String cityName = addresses.get(0).getAddressLine(0);
//String stateName = addresses.get(0).getAddressLine(1);
//String countryName = addresses.get(0).getAddressLine(2);

Get Local Cities names using Google Map API

In my android app, I have to list all local cities names using my current location with Google Map API
Input
Current Co-ordinates
Current place Name.
Output
Local cities of current place.

You must collect the latitude and longitude first.
then you can user geocoder to get it. Like :-
Geocoder gcd = new Geocoder(context, Locale.getDefault());
List<Address> addresses = gcd.getFromLocation(lat, lng, 1);
if (addresses.size() > 0)
System.out.println(addresses.get(0).getLocality());

Try this way
public List<Address> getAddressListFromLatLong(double lat, double lng) {
Geocoder geocoder = new Geocoder(this);
List<Address> list = null;
try {
list = geocoder.getFromLocation(lat, lng, 20);
// 20 is no of address you want to fetch near by the given lat-long
for (Address address : list) {
System.out.println(address);
}
} catch (Throwable e) {
e.printStackTrace();
}
return list;
}

Distance of Location from a zip (postal) code

The Android API has Location.distanceBetween(), which accepts two lat/lon values and returns a distance in meters. Is there a way that I could get this distance with only having a zip (postal) code for one of my points?

You may want to use Android's Geocoder API. Something like this should work:
String locationName = zipCode + ", " + countryName;
Geocoder geoCoder = new Geocoder(context, Locale.getDefault());
try {
List<Address> address = geoCoder.getFromLocationName(locationName, 1);
double latitude = address.get(0).getLatitude();
double longitude = address.get(0).getLongitude();
Location.distanceBetween(...);
} catch (IOException e) {
e.printStackTrace();
}
You need to include the country's name because of this: Get latitude and longitude based on zip using Geocoder class in Android

How to get the location of user after getting longitude and latitude

I am new to android mobile development. I have used the Location Manager class and successfully found out the Longitude and the Latitude of the user. I want to use these values to find the city name. I don't want maps, I just want to get the city name. How do I do this?

First get Latitude and Longitude using Location and LocationManager class(That you have completed). 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() ).

You can use the Geocoder
Geocoder myLocation = new Geocoder(context, Locale.getDefault());
List<Address> myList = null;
try {
myList = myLocation.getFromLocation(latitude, longitude, 1);
} catch (IOException e) {}
Where longitude and latitude are the valued retrieved by networks or GPS

Getting street name from Address/Location object in Android

I'm trying to get the street name of my current location but I can't seem to get it.
I use this method to retrieve the Address:
public Address getAddressForLocation(Context context, Location location) throws IOException {
if (location == null) {
return null;
}
double latitude = location.getLatitude();
double longitude = location.getLongitude();
int maxResults = 1;
Geocoder gc = new Geocoder(context, Locale.getDefault());
List<Address> addresses = gc.getFromLocation(latitude, longitude, maxResults);
if (addresses.size() == 1) {
return addresses.get(0);
} else {
return null;
}
}
And then I can do things like. address.getLocality() and address.getPostalCode()
But what I want is the street name. Like in "Potterstreet 12". When I print the AddressLine(0) and AddressLine(1) I only get the postalcode, city and country.
How can I retrieve the street name of the position i'm currently at?

Have you tried using getAddressLine ?
See here for more info on this method
Something like this should do (untested):
for (int i = 0; i < addresses.getMaxAddressLineIndex(); i++) {
Log.d("=Adress=",addresses.getAddressLine(i));
}

Try something like this in your code
String cityName=null;
Geocoder gcd = new Geocoder(getBaseContext(),Locale.getDefault());
List<Address> addresses;
try {
addresses = gcd.getFromLocation(location.getLatitude(), location
.getLongitude(), 1);
if (addresses.size() > 0)
StreetName=addresses.get(0).getThoroughfare();
String s = longitude+"\n"+latitude +
"\n\nMy Currrent Street is: "+StreetName;
Toast.makeText(getApplicationContext(), s, Toast.LENGTH_LONG).show();
it works for me :-) Good luck ;-)

If you have a complete address (city + street), in
address.getAddressLine(0)
you find the street name and number.

getFromLocation wasn't working for me either. There are a couple steps you can take.
1. First off go into gradle and make sure you are using the latest play services lib.
2. Don't over specify, the reason I got no results is because I had to much info in my address. When I removed the postal code I got results every time.
3. Try the online api:
http://maps.google.com/maps/api/geocode/json?address=192%20McEwan%20Dr%20E,%20Caledon,%20ON&sensor=false
Just replace the address in there with yours.
Good luck

I had a very similar problem but with the Country name, this is the function I ended up using:
function getCountry(results) {
var geocoderAddressComponent,addressComponentTypes,address;
for (var i in results) {
geocoderAddressComponent = results[i].address_components;
for (var j in geocoderAddressComponent) {
address = geocoderAddressComponent[j];
addressComponentTypes = geocoderAddressComponent[j].types;
for (var k in addressComponentTypes) {
if (addressComponentTypes[k] == 'country') {
return address.long_name;
}
}
}
}
return 'Unknown';
}
You should be able to adapt this to get the street name out without much fuss.
Inspired by this answer

Geocoder gcd = new Geocoder(this, Locale.getDefault());
List<Address> addresses =
gcd.getFromLocation(currentLatitude, currentLongitude,100);
if (addresses.size() > 0 && addresses != null) {
StringBuilder result = new StringBuilder();
myaddress.setText(addresses.get(0).getFeatureName()+"-"+addresses.get(0).getLocality()+"-"+addresses.get(0).getAdminArea()+"-"+addresses.get(0).getCountryName());
}
getfeaturename() return Streetname
getlocality() return city
getadminarea() return State
That's All..!
