Google map Activity(Not getting lat,lang)

Here I'm trying to get the current location on the google maps activity. but it is no fetching the latitude or longitude when the map page is loaded. Assist me here. while checking with the breakpoints, latitude, and longitude values are null.
private void configureCameraIdle() {
onCameraIdleListener = new GoogleMap.OnCameraIdleListener() {
#Override
public void onCameraIdle() {
LatLng latLng = mMap.getCameraPosition().target;
Geocoder geocoder = new Geocoder(TrialActivity.this);
try {
addressList = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1);
if (addressList != null && addressList.size() > 0) {
String locality = addressList.get(0).getAddressLine(0);
String country = addressList.get(0).getCountryName();
System.out.println("Address "+addressList.get(0).getAddressLine(0));
System.out.println("getAdminArea "+addressList.get(0).getAdminArea());
System.out.println("getCountryCode "+addressList.get(0).getCountryCode());
System.out.println("getCountryName "+addressList.get(0).getCountryName());

if (locality!=null && country!=null)
{

how to convert longitude and latitude into text format to show street address?

I am developing an app,In this I'm using google map to show users current location.
Following code I am using but it doesn't give the result of street address only shows the current location in map and shows longitude and latitude.How do I show the current street address in text field from current longitude and latitude?
//java

You can use Double.toString() to convert a double to a String. Alternatively, you can use +:
"" + latitude
If you need more control over the output, such as the number of decimal places to display, you can use String.format().

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");
}
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);
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);
message.setData(bundle);
}
message.sendToTarget();
}
}
};
thread.start();

You should split your Snippet Marker text and extract all the details.
see below
public void onInfoWindowClick(Marker marker) {
String[] str2 = marker.getSnippet().split(",");
String Addressline1=str2[0]; //Addressline 1
String Addressline2=str2[1]; //Addressline 2
String phone=str2[2]; //Phone
Toast.makeText(this, marker.getTitle() + "--" + marker.getSnippet()+"-- "+phone,
Toast.LENGTH_LONG).show();
}

How to get country name in android?

Hi I am working with android.I had created a GPS app for getting the current location.Now How can I get the country name from the latitude and longitude value ? is it possible ? please help me and thanks :)
here is my code I used
public class AndroidGPSTrackingActivity extends Activity {
Button btnShowLocation;
// GPSTracker class
GPSTracker gps;
String countryCode,countryName;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnShowLocation = (Button) findViewById(R.id.btnShowLocation);
// show location button click event
btnShowLocation.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// create class object
gps = new GPSTracker(AndroidGPSTrackingActivity.this);
// check if GPS enabled
if(gps.canGetLocation()){
double latitude = gps.getLatitude();
double longitude = gps.getLongitude();
Log.i("location", " "+latitude+" "+longitude);
// \n is for new line
try
{Geocoder gcd = new Geocoder(getApplicationContext(), Locale.getDefault());
List<Address> addresses = gcd.getFromLocation(latitude,longitude, 1);
if (addresses.size() > 0)
Toast.makeText(getApplicationContext(), "name "+addresses.get(0).getLocality(),Toast.LENGTH_SHORT).show();
//System.out.println(addresses.get(0).getLocality());
}
catch (IOException e) {
e.printStackTrace();
}
//Toast.makeText(getApplicationContext(), "Your Location is - \nLat: " + latitude + "\nLong: " + longitude+countryName +" "+countryCode, Toast.LENGTH_LONG).show();
}else{
// can't get location
// GPS or Network is not enabled
// Ask user to enable GPS/network in settings
gps.showSettingsAlert();
}
}
});
}
}

String country_name = null;
LocationManager lm = (LocationManager)getApplicationContext().getSystemService(Context.LOCATION_SERVICE);
Geocoder geocoder = new Geocoder(getApplicationContext());
for(String provider: lm.getAllProviders()) {
#SuppressWarnings("ResourceType") Location location = lm.getLastKnownLocation(provider);
if(location!=null) {
try {
List<Address> addresses = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 1);
if(addresses != null && addresses.size() > 0) {
country_name = addresses.get(0).getCountryName();
break;
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
Toast.makeText(getApplicationContext(), country_name, Toast.LENGTH_LONG).show();

Finally I got the solution, without lat and long value, i got country name.
String country = getApplicationContext().getResources().getConfiguration().locale.getDisplayCountry();
.

Use this:
Geocoder myLocation = new Geocoder(AppContext);
try
{
myList = myLocation.getFromLocation(latitude, longitude, 1);
}
catch (Exception e)
{
e.printStackTrace();
}
if(myList != null)
{
try
{
String country = myList.get(0).getCountryName();}

You can Get Country name from below mentioned json. Just pass your lat-long in address. And look for "long_name" which have "country,political" in "types" array.
i.e. http://maps.googleapis.com/maps/api/geocode/json?address=23.022505,72.5713621&sensor=false

From a Geocoder object, you can call the getFromLocation(double, double, int) method. It will return a list of Address objects that have a method getLocality().
import android.location.Address;
import android.location.Geocoder;
Geocoder gcd = new Geocoder(this, Locale.getDefault());
List<Address> addresses;
try {
addresses = gcd.getFromLocation(1.2, 2.2256, 1);
if (addresses.size() > 0)
System.out.println(addresses.get(0).getLocality());
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

List<Address> addresses=null;
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
try {
addresses = geocoder.getFromLocation(loc.latitude, loc.longitude, 1);
System.out.println("add in string "+addresses.toArray().toString());
String countryName = addresses.get(0).getCountryName();
String countryCode = addresses.get(0).getCountryCode();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
