Getting longitude and latitude from lastKnownLocation()?

I've got a activity that onCreate, it calculates the distance between your location and a event that is nearby, I've used lastKnownLocation to get the current device location and put a marker of it on a google map, but I need it to write the longitude and latitude outside of it's method to be used to calculate distances.
I've used LocationManager to get the rough coordinates but these aren't accurate enough and has a distance of 50 miles for something that's not even half a mile away. I currently have it so will overwrite longitude and latitude got from LocationManager but it does not.
I've attempted to use LocationRequest too and that hasn't helped.
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setInterval(60000);
locationRequest.setFastestInterval(5000);
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
LocationCallback locationCallback = new LocationCallback() {
#Override
public void onLocationResult(LocationResult locationResult){
if(locationRequest==null){
return;
}
for(Location location : locationResult.getLocations()) {
if (location != null){
userLat=location.getLatitude();
userLng=location.getLongitude();
}
}
}
};
LocationServices.getFusedLocationProviderClient(EventLocator.this).requestLocationUpdates(locationRequest,locationCallback, null);
LocationServices.getFusedLocationProviderClient(EventLocator.this).getLastLocation().addOnSuccessListener(new OnSuccessListener<Location>() {
#Override
public void onSuccess(Location location) {
if(location!=null){
double longitude=location.getLongitude();
double latitude=location.getLatitude();
userLng=longitude;
userLat=latitude;
}
}
});
All the permissions are correct, as I said I've used getLastLocation() to place a marker.

Make sure you added location permission in manifest file
If you are using android os 6 above make sure you have location permission
Make sure you GPS service is enabled in you mobile
public Location getLocation() {
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
if (locationManager != null) {
Location lastKnownLocationGPS = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (lastKnownLocationGPS != null) {
return lastKnownLocationGPS;
} else {
Location loc = locationManager.getLastKnownLocation(LocationManager.PASSIVE_PROVIDER);
System.out.println("1::"+loc);----getting null over here
System.out.println("2::"+loc.getLatitude());
return loc;
}
} else {
return null;
}
}
If still not working try to restart your phone and then try again.

You can create interface and implement it in the class where you need to calculate the distance

Usually GPS takes time to warm up. Your initial location reading could be from a cold GPS. In order to get a more accurate reading keep reading results until you get an accuracy reading that works for you.
Keep in mind GPS on a phone is not very accurate and would not be able to get accurate readings inside buildings or if not enough coverage is in your area at the time.
Last know position does not give you your current position, like it says it is the last know position which could have been more than a few minutes ago. Also it could've come from a cell tower reading instead of a GPS reading.

I'm using this code
lateinit var fusedLocationProviderClient: FusedLocationProviderClient
lateinit var latitude : Double
lateinit var longitude : Double
override fun onCreate() {
super.onCreate()
fusedLocationProviderClient = FusedLocationProviderClient(this)
updateLocationTracking()
}
#SuppressLint("MissingPermission")
private fun updateLocationTracking() {
if(PermissionUtility.isPermissionsGranted(this, Manifest.permission.ACCESS_FINE_LOCATION)) {
val request = LocationRequest().apply {
interval = LOCATION_UPDATE_INTERVAL
fastestInterval = FASTEST_LOCATION_INTERVAL
priority = PRIORITY_HIGH_ACCURACY
}
fusedLocationProviderClient.requestLocationUpdates(
request,
locationCallback,
Looper.getMainLooper()
)
}
}
private val locationCallback = object : LocationCallback() {
override fun onLocationResult(result: LocationResult?) {
super.onLocationResult(result)
result?.locations?.let { locations ->
for(location in locations) {
setLocationData(location)
}
}
}
}
private fun setLocationData(location : Location){
latitude = location.latitude
longitude = location.longitude
}
}

So I figured it out when I couldn't use my phone I use for debugging and used my personal phone for testing, went on the activity and the distances were correct.
Messed around with both debug phone settings and using GPS_PROVIDER and NETWORK_PROVIDER and when my phone used just GPS to get location, it got nothing. Other phone can, so think it's safe to say my debug phone's GPS is borked.
It's a old phone that, when I got a new one, I factory reset to use for debugging, as it helped with the backwards compatibility for older phones and smaller screens. I never thought if the actual hardware was faulty too after the reset.
So error was with the phone itself not the app. Guess it goes to show have two devices to test on.

Cannot get current location

I need to get current device location (lat/lng) but "getCurrentLocation()" shows "No provider" all the time so location is null. I call this method in onCreate() and declared all permissions in Manifest file:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
Location services on real device are enabled as well.
getCurrentLocation() java code:
public void getCurrentLocation() {
locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
Criteria c = new Criteria();
provider = locationManager.getBestProvider(c, false);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
location = locationManager.getLastKnownLocation(provider);
if(location!=null)
{
double lng=location.getLongitude();
double lat=location.getLatitude();
Toast.makeText(this, Double.toString(lat) + "\n" + Double.toString(lng), Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(this, "No provider", Toast.LENGTH_SHORT).show();
}
}
How can I fix it?
P.S.: I revised a lot of similar questions but can't find suitable solution.

First of all consider using FusedLocationProvider instead of LocationManager. Here you can find guide to how to use id.
Second - you are trying to get "last known location" and it wouldn't always be there. To receive users location you need to subscribe to LocationManager updates. This is example how to do it.

provider = locationManager.getBestProvider(c, true);
try this change in your code

It is not guaranteed that .getLastKnownLocation() returns a previously stored location data.
It can return a null.
So you have to be prepared for the case where you need to listen for location updates. You register to them like this:
locationManager
.requestLocationUpdates(provider, 0, 0,
new LocationListener() {
#Override
public void onLocationChanged(Location location) {
//here you receive the new location
}
#Override
public void onStatusChanged(String s, int i, Bundle bundle) {
}
#Override
public void onProviderEnabled(String s) {
}
#Override
public void onProviderDisabled(String s) {
}
}););

Getting the user's location in Android when the phone is locked

I am looking for a solution to get the user's location in a specific time-interval in Android API 17 (Android 4.2) and when the phone is locked.
I've already tried some different code, checked a lot tutorials and searched almost everywhere on the web. The solution might be there, but I think it's a combination of lack of experience with Android developing and interpreting the different right solutions and approaches.
At first I had some pretty basic code, which worked very well when the screen was turned on. Even in the background, the location got updated (as I could check via a Toast message with the longitude and latitude).
I used a Handler to do so:
public void locationRunnable() {
final Handler locationHandler = new Handler();
final int distanceDelay = 5000; // milliseconds
locationHandler.postDelayed(new Runnable(){
public void run() {
// code
mMap.clear();
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
mMap.setMyLocationEnabled(true);
mMap.setBuildingsEnabled(true);
mMap.getUiSettings().setMyLocationButtonEnabled(false);
LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
String provider = locationManager.getBestProvider(criteria, true);
myLocation = locationManager.getLastKnownLocation(provider);
if (myLocation != null) {
latitudeCurrentPosition = myLocation.getLatitude();
longitudeCurrentPosition = myLocation.getLongitude();
}
currentPattern = shortTest;
Notification.Builder notificationBuilderChecking = new Notification.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
.setContentTitle("Test app")
.setAutoCancel(true)
.setOnlyAlertOnce(false)
.setContentText("Getting location!")
.setPriority(Notification.PRIORITY_MAX)
.setLights(0xffffffff, 200, 200)
.setVibrate(currentPattern);
Notification notification2 = notificationBuilderChecking.build();
NotificationManager notificationMngr2 = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationMngr2.notify(NOTIFICATION_ID, notification2);
locationHandler.postDelayed(this, distanceDelay);
}
}, distanceDelay);
}
It's just a snippet and the purpose is that in the background, when the screen is locked, this will loop every 10 seconds. And it does. Even when the phone is locked, but only for about 3 times. After 3 times the timer goes up and the phone vibrates less frequent (Doze feature in the way?).
Also, the phone does vibrate, but the location isn't updated. When I unlock the phone with the app in the foreground, the location is still at the place when I locked the phone. After a while (10 seconds) it updates. I use a marker on the map to check.
Again: it works when the phone is unlocked.
Now I'm trying to use a Service, a Service (Intent Service), or a Broadcast Receiver, and start a new Thread, but I don't know how and nothing is working.
Some of the last code I have contains a not functioning Broadcast Receiver and the most recent code contains a AlarmManager:
public void getLocation(Context context) {
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, AlarmIntent.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0);
//After after 30 seconds
am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, System.currentTimeMillis(), 10000, pi);
context.getSystemService(Context.CONNECTIVITY_SERVICE);
mMap.clear();
mMap.setMyLocationEnabled(true);
mMap.getUiSettings().setMyLocationButtonEnabled(false);
LocationManager locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
String provider = locationManager.getBestProvider(criteria, true);
myLocation = locationManager.getLastKnownLocation(provider);
latitudeCurrentPosition = myLocation.getLatitude();
longitudeCurrentPosition = myLocation.getLongitude();
LatLng latLngCurrent = new LatLng(latitudeCurrentPosition, longitudeCurrentPosition);
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLngCurrent));
mMap.animateCamera(CameraUpdateFactory.zoomTo(distZoom));
currentPattern = shortTest;
showNotification(context);
mHereIAm = mMap.addMarker(new MarkerOptions()
.position(new LatLng(latitudeCurrentPosition, longitudeCurrentPosition))
.title(weAreHere)
.draggable(false)
.icon(BitmapDescriptorFactory
.fromResource(R.drawable.marker_iconv3)));
mHereIAm.setTag(0);
mHereIAm.showInfoWindow();
}
AndroidManifest permissions:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.android.alarm.permission.SET_ALARM" />
But at the long of 10000, Android Studio is telling me "Value will be forced up to 60000 as of Android 5.1; don't rely on this to be exact..." etc. So an AlarmManager isn't useful either.
With the last code, my app isn't even running anymore.
But still: vibrations and stuff still occur, but location updates don't.
In short:
I need some basic (at least, I think it just can't be so difficult, as the only problem is that it's not working when the screen is locked) code, that updates my location on a certain, variable interval.
Maybe I have to use a Handler/Runnable, start a new Thread, use a Service or a Broadcast Receiver. Maybe an AlarmManager may work as well, but I don't know how and which to use.
This is my first post. If anything misses or you guys need more information, please ask. I'm trying to be as precise as possible, without using to much overhead.
Edit 01
Can I use a Job Service to do so? - I've updated the API to 21, so I can make use of this service, but I don't know if that's the right solution I'm looking for? Got some great tutorials for the use of it.
Edit 02
Let me be more clear with less overhead: I am looking for a solution to get the user's current location when the device is locked: with an API, a Service, an IntentService, a BroadcastReceiver, ... - every tutorial tells me something different, even here at Stack Overflow I have troubles with finding the right solution.
I was able to use a Service as well as an Intent Service, but I cannot request any location updates, because of some errors, like:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.name.name/com.name.name.MapsActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'void com.google.android.gms.maps.GoogleMap.setMyLocationEnabled(b‌​oolean)' on a null object reference - searching for a solution for this error, gives me another error later on, and on, and on... I got myself stuck in an error-loop and a lot of unnecessary code.
I hope there is a simple way to get the user's location and you guys could help me. Thanks again.
Edit 03
I've followed the instructions on this tutorial and the location is checking. See the following code:
public class LocationService extends Service implements LocationListener {
private final Context mContext;
// flag for GPS status
boolean isGPSEnabled = false;
// flag for network status
boolean isNetworkEnabled = false;
// flag for GPS status
boolean canGetLocation = false;
Location location; // location
double latitude; // latitude
double longitude; // longitude
// The minimum distance to change Updates in meters
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meters
// The minimum time between updates in milliseconds
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute
// Declaring a Location Manager
protected LocationManager locationManager;
public LocationService(Context context) {
this.mContext = context;
getLocation();
}
public Location getLocation() {
try {
locationManager = (LocationManager) mContext
.getSystemService(LOCATION_SERVICE);
// getting GPS status
isGPSEnabled = locationManager
.isProviderEnabled(LocationManager.GPS_PROVIDER);
// getting network status
//isNetworkEnabled = locationManager
// .isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (!isGPSEnabled && !isNetworkEnabled) {
// no network provider is enabled
} else {
this.canGetLocation = true;
// First get location from Network Provider
if (isNetworkEnabled) {

I've disabled Network location and only allowed GPS location for testing - tested both.
And my MapsActivity:
public void getLocation(){
gps = new LocationService(MapsActivity.this);
if(gps.canGetLocation()) { // gps enabled} // return boolean true/false
latitudeCurrentPosition = gps.getLatitude(); // returns latitude
longitudeCurrentPosition = gps.getLongitude(); // returns longitude
latLngCurrent = new LatLng(latitudeCurrentPosition, longitudeCurrentPosition);
Toast toastLatCur = makeText(getApplicationContext(), "Lat Current: " + latitudeCurrentPosition + "" ,Toast.LENGTH_SHORT);
toastLatCur.show();
Toast toastLongCur = makeText(getApplicationContext(), "Long Current: " + longitudeCurrentPosition + "" ,Toast.LENGTH_SHORT);
toastLongCur.show();
}
else {
gps.showSettingsAlert();
}
if(goToLocation){
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLngCurrent));
goToLocation = false;
if(firstStart){
mMap.animateCamera(CameraUpdateFactory.zoomTo(distZoom));
firstStart = false;
}
}
vibrateNotification();
}
When the screen is locked, the phone vibrates as I told in vibrateNotificatoin() - works perfectly every 10 seconds. But the location doesn't get updated! So a Service is not the right way to solve this. Help!

You should use the service to perform tasks which are needed to be done even when the application is not running. Give a try.

get latitude and longitude in Android without show the map [duplicate]

This question already has an answer here:
android requestLocationUpdates failing
(1 answer)
Closed 2 years ago.
Is there a way to obtain information without displaying the map?
I want get my coordinate of my place during the work with other activity.
tnx a lot.

By Using LocationManager you can get lat and lang :
LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
double longitude = location.getLongitude();
double latitude = location.getLatitude();
The call to getLastKnownLocation() doesn't block - which means it will return null if no position is currently available - so you probably want to have a look at passing a LocationListener to the requestLocationUpdates() method instead, which will give you asynchronous updates of your location.
private final LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
longitude = location.getLongitude();
latitude = location.getLatitude();
}
}
lm.requestLocationUpdates(LocationManager.GPS, 2000, 10, locationListener);
You'll need to give your application the ACCESS_FINE_LOCATION permission if you want to use GPS.
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
You may also want to add the ACCESS_COARSE_LOCATION permission for when GPS isn't available and select your location provider with the getBestProvider() method.

Using this code able to get latitude and Longitude values and make
sure before using application you got permission from manifest for accessing location
if(isGPS) {
Geocoder gc = new Geocoder(getApplicationContext(), Locale.getDefault());
try
{
double lat=location.getLatitude();
double lng=location.getLongitude();
Toast.makeText(getApplicationContext(),lat+"and"+lng, Toast.LENGTH_LONG).show();
}
catch (Exception e)
{
e.printStackTrace();
}
}
else
{
display("GPS not Enabled");
}
Manifest permission
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Use this if you want to get lat lon without internet
LocationManager lm = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);
Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
latitude = location.getLongitude();
longitude = location.getLatitude();

Criteria criteria = new Criteria();
provider = locationManager.getBestProvider(criteria, false);
locationManager.requestLocationUpdates(provider, 0, 0, this);
Location location = locationManager.getLastKnownLocation(provider);
onLocationChanged(location);

Log.e("GPS", "location changed: lat="+lat+", lon="+lng);
latituteField.setText(String.valueOf(lat));
longitudeField.setText(String.valueOf(lng));

Or I need to do something such as passing latitude or longitude value from somwhere? Or it will automatically get the current location value?
I have these in my manifest file-
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />

<uses-permission android:name="android.permission.CONTROL_LOCATION_UPDATES" />
<uses-permission android:name="android.permission.INTERNET" />
Anything else I need to add?
And also I am getting this error when I saw in logCAT

I am getting in my textbox as Provider Not Available as it is going to else loop.

As you mentioned in the comment that you are running your code from eclipse. Let me tell you that, can not fetch the real GPS Co-Ordinates in Eclipse. However you can simulate it by load .gpx file in to DDMS.
Have a visit my answer for same purpose.

int lat = (int) (location.getLatitude());
int lng = (int) (location.getLongitude());
you should have double instead of int, Do you know lat, longs are in double and you are only taking integer part. location changes even after 4 decimal places.
