No Location Provider Found in Lollipop and Marshmallow

I working with a project to find the address using latitude and longitude. I got answer in Jellybean but when comes to Lollipop and Marshmallow it only showing latitude and longitude, not getting address. It shows location provider is not found. Is there any error in my code?
locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
mprovider = locationManager.getBestProvider(criteria, false);
if (mprovider != null && !mprovider.equals("")) {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) !=
PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
return;
}
Location location = locationManager.getLastKnownLocation(mprovider);
locationManager.requestLocationUpdates(mprovider,5000, 0,this);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
if (location != null)
onLocationChanged(location);
else
Toast.makeText(getBaseContext(), "No Location Provider Found Check Your Code", Toast.LENGTH_SHORT).show();
}
}
#Override
public void onLocationChanged(Location location) {
TextView longitude = (TextView) findViewById(R.id.textView);
TextView latitude = (TextView) findViewById(R.id.textView1);
longitude.setText("Current Longitude:" + location.getLongitude());
latitude.setText("Current Latitude:" + location.getLatitude());
Geocoder geo = new Geocoder(getApplicationContext(), Locale.getDefault());
// String mylocation;
try {
List < Address > addresses = geo.getFromLocation(location.getLatitude(), location.getLongitude(), 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()
address1.setText(address);
String city = addresses.get(0).getLocality();
textViewCity.setText(city);
String state = addresses.get(0).getAdminArea();
textViewState.setText(state);
String country = addresses.get(0).getCountryName();
textViewCountry.setText(country);
String postalCode = addresses.get(0).getPostalCode();
textViewPostal.setText(postalCode);
String knownName = addresses.get(0).getFeatureName();
System.out.println("Address >> " + address + " " +city+ " \n" + state + " \n" + country+ "\n"+postalCode+ "\n"+knownName);
}
} catch (IOException e) {

add this class.

// consider returning Location instead of this dummy wrapper class
public static class GPSCoordinates {
public float longitude = -1;
public float latitude = -1;
public GPSCoordinates(float theLatitude, float theLongitude) {
longitude = theLongitude;
latitude = theLatitude;
}
public GPSCoordinates(double theLatitude, double theLongitude) {
longitude = (float) theLongitude;
latitude = (float) theLatitude;
}
}
}
and use like this:
SingleShotLocationProvider.requestSingleUpdate(getActivity(),
new SingleShotLocationProvider.LocationCallback() {
#Override
public void onNewLocationAvailable(SingleShotLocationProvider.GPSCoordinates location) {
lat = location.latitude;
lag = location.longitude;
}
});
here you can get lat - lag if your device location is enable. so also check that is enable or not.
if (!manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
showEnableLocationDialog();
} else {
SingleShotLocationProvider.requestSingleUpdate(getActivity(),
new SingleShotLocationProvider.LocationCallback() {
#Override
public void onNewLocationAvailable(SingleShotLocationProvider.GPSCoordinates location) {
lat = location.latitude;
lag = location.longitude;
}
});
}
public void showEnableLocationDialog() {
final android.app.AlertDialog.Builder builderDialog = new android.app.AlertDialog.Builder(getActivity());
builderDialog.setTitle("Enable Location");
builderDialog.setMessage("Please enable location for near by search");
builderDialog.setPositiveButton("Enable",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Intent myIntent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(myIntent);
}
});
builderDialog.setNegativeButton("No",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
//fetchImages();
}
});
android.app.AlertDialog alert = builderDialog.create();
alert.show();
}
and i hope you are asking run-time permission for location first. otherwise you will never get location.

How to get Current Location(Street,City, etc,..) using gps in Android

I want to create a app to Track the Users who installed my App, So i have a following code for tracking, This code working good but it will return only CITY NAME. But i need full details like street name, city, like wise .

Use fused Location Provider to get current device latitude and longitude.
With the help of latitude and longitude, you can get city name and address.
To get full street name, use getMaxAddressLineIndex().
In onLocationChanged, check whether you are getting current location or not.
Edit:
String strAdd = "";
#Override
public void onLocationChanged(Location loc) {
editLocation.setText("");
pb.setVisibility(View.INVISIBLE);
Toast.makeText(getBaseContext(),"Location changed : Lat: " +
loc.getLatitude()+ " Lng: " + loc.getLongitude(),
Toast.LENGTH_SHORT).show();
String longitude = "Longitude: " +loc.getLongitude();
Log.v(TAG, longitude);
String latitude = "Latitude: " +loc.getLatitude();
Log.v(TAG, latitude);
/*----------to get City-Name from coordinates ------------- */
String cityName=null;
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(TabClubActivity.this, Locale.getDefault());
try {
addresses = geocoder.getFromLocation(latitude, longitude, 1);
if (!addresses.isEmpty()) {
Address returnedAddress = addresses.get(0);
StringBuilder strReturnedAddress = new StringBuilder("");
for (int i = 0; i < returnedAddress.getMaxAddressLineIndex(); i++) {
strReturnedAddress.append(returnedAddress.getAddressLine(i)).append(" ");
}
strAdd = strReturnedAddress.toString();
textview.setText(strAdd);
Log.e("MyCurrentLoctionAddress", "" + strReturnedAddress.toString());
cityName=addresses.get(0).getLocality();
} else {
// Log.e("MyCurrentLoctionAddress", "No Address returned!");
}
} catch (IOException e) {
e.printStackTrace();
}
String s = longitude+"\n"+latitude +
"\n\nMy Currrent City is: "+cityName;
editLocation.setText(s);
}

I tried the Geocoder however the results are unreliable. So better go for the nearbysearch googleapi for the result. It provides the city name directly. Here's the version of my implementation.
interface Api{
String BASE_URL = "https://maps.googleapis.com";
#GET("/maps/api/place/nearbysearch/json")
Call<List<ResultDO>> getPlaceDetailByLatLong(#Query("location") String type,#Query("radius") String radius,#Query("key")String key);
}
And in the main activity or fragment.
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(API.BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
API service = retrofit.create(API.class);
service.getCityResults(types, input, location, radius, key).enqueue(new Callback<List<ResultDO>>() {
#Override
public void onResponse(Call<List<ResultDO>> call, Response<List<ResultDO>> response) {
tvCity.setText(response.body().get(0).getVicinity());// first object gives me the city name
}
#Override
public void onFailure(Call<List<ResultDO>> call, Throwable t) {
}
});

You can get address (street name, city, country, etc) by converting Geographic Location (e.g Latitude, longitude) to address. This process called Reverse Geocoding this doc.
You can use FusedLocationProviderApi(), but it has been deprecated (here). The alternative, You can use FusedLocationProviderClient() to get LastKnownLocation, from LastKnownLocation object (contain latitude and longitude), so we can use to get address like street name, city, country, etc using Geocoder. The sample doc do synchronously. But here i am doing Asynchronously using AsyncTask. Hope this Help.
To get Current Location:
import com.google.android.gms.location.FusedLocationProviderClient;
import com.google.android.gms.tasks.OnCompleteListener;
public class MainActivity extends AppCompatActivity{
//before public class MainActivity extends AppCompatActivity implements LocationListener,...,...
private static final String TAG = "MainActivity";
public static final int MY_PERMISSIONS_REQUEST_FINE_LOCATION = 101;
private FusedLocationProviderClient mFusedLocationClient;
private Location mGetedLocation;
private double currentLat, currentLng;
private void getLastLocation() {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(new String[] {Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSIONS_REQUEST_FINE_LOCATION);
}
return;
}
mFusedLocationClient.getLastLocation()
.addOnCompleteListener(this, new OnCompleteListener<Location>() {
#Override
public void onComplete(#NonNull Task<Location> task) {
if (task.isSuccessful() && task.getResult() != null) {
mGetedLocation = task.getResult();
//currentLat = mGetedLocation.getLatitude();
//currentLng = mGetedLocation.getLongitude();
//start reverse geocoding
//little different with the doc
(new GetAddressTask(this)).execute(mGetedLocation);
}else{
Log.e(TAG, "no location detected");
Log.w(TAG, "getLastLocation:exception", task.getException());
}
}
});
}
To Get Address from LastKnownLocation
//sorry, I forgot where I got this asyncTask code. So I did not mention the source.
//If anyone feels that making this code please comment.
private class GetAddressTask extends AsyncTask<Location, Void, String> {
Context mContext;
GetAddressTask(Context context) {
super();
mContext = context;
}
#Override
protected String doInBackground(Location... params) {
Geocoder geocoder =
new Geocoder(mContext, Locale.getDefault());
// Get the current location from the input parameter list
Location loc = params[0];
// Create a list to contain the result address
List<Address> addresses;
try {
addresses = geocoder.getFromLocation(loc.getLatitude(),
loc.getLongitude(), 1);
} catch (IOException e1) {
Log.e("LocationSampleActivity",
"IO Exception in getFromLocation()");
e1.printStackTrace();
return ("IO Exception trying to get address");
} catch (IllegalArgumentException e2) {
// Error message to post in the log
String errorString = "Illegal arguments " +
Double.toString(loc.getLatitude()) +
" , " +
Double.toString(loc.getLongitude()) +
" passed to address service";
Log.e("LocationSampleActivity", errorString);
e2.printStackTrace();
return errorString;
}
// If the reverse geocode returned an address
if (addresses != null && addresses.size() > 0) {
Address address = addresses.get(0);
/*
address.getLocality(),
address.getCountryName());
*/
return address.getLocality();
} else {
return "No address found";
}
}
#Override
protected void onPostExecute(String address) {
if (address != null)
mtextView.setText(address);//=============================> GOT THIS
}
}

In the Activity Class makes a customized method :
private void getTheUserPermission() {
ActivityCompat.requestPermissions(this, new String[]
{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_LOCATION);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
LocationGetter locationGetter = new LocationGetter(FreshMenuSearchActivity.this, REQUEST_LOCATION, locationManager);
if (!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
locationGetter.OnGPS();
} else {
locationGetter.getLocation();
}
}
Make a UserDefined Class name LocationGetter:-
public class LocationGetter {
private int REQUEST_LOCATION;
private FreshMenuSearchActivity mContext;
private LocationManager locationManager;
private Geocoder geocoder;
public LocationGetter(FreshMenuSearchActivity mContext, int requestLocation, LocationManager locationManager) {
this.mContext = mContext;
this.locationManager = locationManager;
this.REQUEST_LOCATION = requestLocation;
}
public void getLocation() {
if (ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(mContext,
Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(mContext, new String[]
{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_LOCATION);
} else {
Location LocationGps = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
Location LocationNetwork = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
Location LocationPassive = locationManager.getLastKnownLocation(LocationManager.PASSIVE_PROVIDER);
if (LocationGps != null) {
double lat = LocationGps.getLatitude();
double longi = LocationGps.getLongitude();
getTheAddress(lat, longi);
} else if (LocationNetwork != null) {
double lat = LocationNetwork.getLatitude();
double longi = LocationNetwork.getLongitude();
getTheAddress(lat, longi);
} else if (LocationPassive != null) {
double lat = LocationPassive.getLatitude();
double longi = LocationPassive.getLongitude();
getTheAddress(lat, longi);
} else {
Toast.makeText(mContext, "Can't Get Your Location", Toast.LENGTH_SHORT).show();
}
}
}
private void getTheAddress(double latitude, double longitude) {
List<Address> addresses;
geocoder = new Geocoder(mContext, Locale.getDefault());
try {

Android Geocoder doesn't work on API 23

i have develop app that when run take the city name by lat and long using a GPSTracker.java class and add this city name to url for retrive json data.
My code works very fine from API 18 to API 22 but now when i run my code on API 23 the geocoder doesn't work and city name is null
This is my code on Main Activity for retrive city name:

if (addresses.size() > 0) {
System.out.println(addresses.get(0).getLocality());
cityName = addresses.get(0).getLocality();
Log.d("nome_cit", "debug_cit " + cityName);
// Controllo formattazione nomi Car2Go
if(cityName.equals("Rome")) {

Also i have notice that using place picker on API 23 i recive this error:
Attempt to invoke interface method 'int java.util.List.size()' on a null object reference
for this code:

String addresses = place.getAddress().toString();
if (addresses != null) {
puntoA.setText(addresses);
}if (addresses.isEmpty()){
addresses = "(" + place.getLatLng().latitude + "," + place.getLatLng().longitude + ")";
puntoA.setText("nessun indirizzo disponibile " + addresses);
}
//puntoA.setText(addresses);
// Recupero coordinate
Geocoder geocoder = new Geocoder(getActivity());
List<Address> address = null;
try {
address = geocoder.getFromLocationName(addresses, 1);
} catch (IOException e) {
e.printStackTrace();
}
if(address.size() > 0) {
Lat = address.get(0).getLatitude();
Lon = address.get(0).getLongitude();
}
else if (address.size() == 0) {
Lat = place.getLatLng().latitude;
Lon = place.getLatLng().longitude;
}
but also this function works very well on other API version
Any help please?

now my code works fine on API 23 and i use this code:
// To get City-Name from coordinates
GPSTracker gpsTracker = new GPSTracker(getActivity());
Double LatFab = gpsTracker.getLatitude();
Double LonFab = gpsTracker.getLongitude();
List<Address> geocodeMatchess = null;
String Country_;
try {
geocodeMatchess = new Geocoder(getActivity(), Locale.ENGLISH).getFromLocation(gpsTracker.getLatitude(), gpsTracker.getLongitude(), 1);
if (geocodeMatchess.isEmpty()) {
}else {
Country_ = geocodeMatchess.get(0).getLocality();
citta_fab = Country_;
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
hope this hel you

How to get location (lat,lng) in API 23 and above in Android Programmatically?

I am developing an application which enable GPS and get the current location. My code is working fine in all android version expect API 23 i.e. Marshmallows. I am testing in Nexus 5 (API 23), Galaxy Note 3 (API 22).
Here is my code
public void program()
{
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, MINIMUM_TIME_BETWEEN_UPDATES, MINIMUM_DISTANCE_CHANGE_FOR_UPDATES, new MyLocationListener());
if (!locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
AlertDialog.Builder builder = new AlertDialog.Builder(NearBy.this);
builder.setTitle("Location Service is Not Active");
builder.setMessage("Please Enable your location services").setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
}
});
AlertDialog alert = builder.create();
alert.show();
} else if (locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
Location location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = null;
try {
addresses = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 1);
final String cityName = addresses.get(0).getAddressLine(0) + " ";
String stateName = addresses.get(0).getAddressLine(1) + " ";
String countryName = addresses.get(0).getAddressLine(2) + " ";
String country = addresses.get(0).getCountryName() + " ";
String Area = addresses.get(0).getSubAdminArea() + " ";
String Area1 = addresses.get(0).getAdminArea() + " ";
String Area2 = addresses.get(0).getLocality() + " ";
String Area3 = addresses.get(0).getSubLocality();
Log.e("Locaton", cityName + stateName + countryName + country + Area + Area1 + Area2 + Area3);
} catch (IOException e) {
e.printStackTrace();
} catch (NullPointerException e) {
e.printStackTrace();
}
}
}
I am getting NullpointerException at
addresses = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 1);
only in Nexus 5 (API 23). I also granted permission (ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION) in both Mainfest and also during run time.
Kindly provide solution for this.

Problem
The location obtained may be null if the last know location could not be found due to various reasons. Read about it in the docs [here][2]
Reason/How i debugged it
getFromLocation does not throws a nullpointer according to documentation hence the problem is in your location object.
Read here about this method
Remedy
Location location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
Check if the location obtained in the above step is NOT NULL and then proceed with the geocoder.
Code snippet
...
else if (locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
Location location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if(location == null) {
log.d("TAG", "The location could not be found");
return;
}
//else, proceed with geocoding.
Geocoder geocoder = new Geocoder(this, Locale.getDefault());

First In marshmallow add all permission on run time also. Otherwise Please restart your mobile and then check again.

If you are targeting Android M, you need to ask users permission to access device GPS. Here is a not so clean code, but might help u a little bit. A better way to do it would be to create your own permission manager class to handle requests and a alertDialog ativity.
Whats happening below is
1) You are checking if permissions are granted.
2) If not, you are checking if the permissions have been denied previously, In that case, you are showing a rationale, to explain to the user why you need the permissions.
3) You show the request permission popup using ActivityCompat.
4) If user declines, show a snackbar with a view button to take the user to the app info screen, whenever u need to access the GPS but notice that permissions are not granted.
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED ) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.ACCESS_COARSE_LOCATION)) {
showRationale();
} else {
// do request the permission
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 8);
}
}
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED ){
//Start your code
} else {
//Show snackbar
}
}
}
private void showRationale(){
String strDeleteMessage = getResources().getString(R.string.rationale_message11) ;
final View dialogView = LayoutInflater.from(this.getActivity()).inflate(R.layout.dialog_fragment, null);
final AlertDialog storageRationaleAlert = new AlertDialog.Builder(this.getActivity()).create();
storageRationaleAlert.setView(dialogView, 0, 0, 0, 0);
storageRationaleAlert.setCanceledOnTouchOutside(false);
TextView mDialogTitle = (TextView) dialogView.findViewById(R.id.dialog_title);
TextView mDialogDetails = (TextView) dialogView.findViewById(R.id.dialog_details);
mDialogDetails.setVisibility(View.VISIBLE);
Button mCancelButton = (Button) dialogView.findViewById(R.id.cancel_btn);
Button mOkButton = (Button) dialogView.findViewById(R.id.ok_btn);
mOkButton.setText(getString(R.string.dialog_continue));
mDialogDetails.setText(Html.fromHtml(strDeleteMessage));
final Activity activity = this.getActivity();
mOkButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
storageRationaleAlert.dismiss();
//Ask for GPS permission
}
});
mCancelButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
storageRationaleAlert.dismiss();
//Show permission snackbar
}
});
storageRationaleAlert.show();
}
