I tried to get latitude and longitude for current location.
However, when I use the code below, the location listener is not triggered at all.
I've added the LOCATION permission in manifest file.
anyone can help?
Here is the java code:
package com.example.setlocaction;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.util.Log;
import android.widget.Toast;
public class MainActivity extends Activity{
double latitude, longitude, radius;
LocationManager mlocManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Acquire a reference to the system Location Manager
mlocManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener()
{
public void onLocationChanged(Location loc)
{
// Called when a new location is found by the network location provider.
Log.i("loc","location changed");
if (loc!=null)
{
loc.getLatitude();
loc.getLongitude();
String Text = "My current location is: " +
"Latitud =" + loc.getLatitude() +
"Longitud = " + loc.getLongitude();
Toast.makeText( getApplicationContext(),Text,Toast.LENGTH_SHORT).show();
}
}
public void onStatusChanged(String provider, int status, Bundle extras)
{}
public void onProviderEnabled(String provider)
{}
public void onProviderDisabled(String provider)
{}
};
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
// 高精度
criteria.setAltitudeRequired(false);
criteria.setBearingRequired(false);
criteria.setCostAllowed(true);
criteria.setPowerRequirement(Criteria.POWER_LOW);
String provider = mlocManager.getBestProvider(criteria, true);
mlocManager.requestLocationUpdates(provider, 2000, 0, locationListener);
Location loc=mlocManager.getLastKnownLocation(provider);
if (loc==null)
{
Log.i("loc","loc=null");
}
}
}

First of all, your current solution utilizes "getLastKnownLocation" which means, that if you actually retrieve the longitude and latitude, you cannot be certain that it will return the current position of the user. It simply returns the location which was last found which can be miles away.
That is nothing wrong in doing so, but it leaves for uncertainty.
Instead, I have personally implemented a location manager for retrieving the current position of the user by utilizing the code provided in the following post which works great:
https://stackoverflow.com/a/17290348/2399772
By using this specific code, you will also be given the advantage that it tries to utilize the WiFi connection first for determining the position which is slightly better. It that doesn't work, it will utilize the GPS instead. Additionally, if GPS services aren't enabled, a dialogue will be shown telling the user to enable those.
Hope this helps.
Additional notes
As I have stated in a previous post, the Geolocation API will does unfortunately not work on all devices. You can hereby consider using the Reverse Geocoding API instead, which is additionally much more reliable:
https://developers.google.com/maps/documentation/geocoding/
It simply requires that you send a HTTP request which should contain latitude and longitude, whereafter it will provide a response in JSON which is easily parsed.
Sometimes it takes a while for the device to deliver the first locations if you haven't used the GPS before. Also, make sure you're in a location where you can gps updates, or try on the emulator using geo fix via telnet.
try this
public class MyLocationActivity extends Activity implements LocationListener {
private LocationManager mgr;
private String best;
public static double myLocationLatitude;
public static double myLocationLongitude;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mgr = (LocationManager) getSystemService(LOCATION_SERVICE);
dumpProviders();
Criteria criteria = new Criteria();
best = mgr.getBestProvider(criteria, true);
Log.d("best provider", best);
Location location = mgr.getLastKnownLocation(best);
dumpLocation(location);
//may be some intent here
}

}
#Override

mgr.requestLocationUpdates(best, 15000, 1, this);
}
private void dumpLocation(Location l) {
if (l == null) {
myLocationLatitude = 0.0;
myLocationLongitude = 0.0;
} else {
myLocationLatitude = l.getLatitude();
myLocationLongitude = l.getLongitude();
}
}
private void dumpProviders() {
List<String> providers = mgr.getAllProviders();
for (String p : providers) {

}
}
private void dumpProviders(String s) {
LocationProvider info = mgr.getProvider(s);
StringBuilder builder = new StringBuilder();
builder.append("name: ").append(info.getName());
}
}
Add following code to your java file
private void GetLocation()
{
LocationDetail pref_LocationDetail = new LocationDetail(_context);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if(objCommon.isOnline(_context))
{

return ;
}
else if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER))
{
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER ,
MINIMUM_TIME_BETWEEN_UPDATES,
MINIMUM_DISTANCE_CHANGE_FOR_UPDATES,
new MyLocationListener()
);
return ;
}
}
}
private class MyLocationListener implements LocationListener
{
public void onLocationChanged(Location location)
{
LocationDetail pref_LocationDetail = new LocationDetail(_context);
double Lattitude = location.getLatitude();
double Longitude = location.getLongitude();
Toast.makeText(_context , location.getProvider().toString() , Toast.LENGTH_LONG).show();
locationManager.removeUpdates(this);
locationManager = null;
}
public void onStatusChanged(String s, int i, Bundle b) {
Toast.makeText(_context , "Provider status changed",
Toast.LENGTH_LONG).show();
}
public void onProviderDisabled(String s) {
Toast.makeText(_context ,
"Provider disabled by the user. GPS turned off",
Toast.LENGTH_LONG).show();
}
public void onProviderEnabled(String s) {
Toast.makeText(_context ,
"Provider enabled by the user. GPS turned on",
Toast.LENGTH_LONG).show();
}
}
just add following code in your manifest
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />

I have code to get location, which I believe must be working but it doesn't at all:
Manifest:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
Java:
LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
0,
0,
new MyLocationListener()
);
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
criteria.setAltitudeRequired(false);
criteria.setBearingRequired(false);
criteria.setCostAllowed(true);
criteria.setPowerRequirement(Criteria.POWER_LOW);
String provider = locationManager.getBestProvider(criteria, true);
Location location = locationManager.getLastKnownLocation(provider);
System.out.println("location: " + location);
location prints null and the listener never get called at all. Anyone can advise what's wrong? If I open Google Maps, it can return my location anyway.
Note: I am testing with my device
Create Class SingleShotLocationProvider in your utility package or wherever you are fine with below code.
import android.content.Context;
import android.content.pm.PackageManager;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.support.v4.app.ActivityCompat;
import android.widget.Toast;
public class SingleShotLocationProvider {
public interface LocationCallback {
void onNewLocationAvailable(Location location);
}
// calls back to calling thread, note this is for low grain: if you want higher precision, swap the
// contents of the else and if. Also be sure to check gps permission/settings are allowed.
// call usually takes <10ms
public static void requestSingleUpdate(final Context context, final LocationCallback callback) {
final LocationManager locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
if (Utility.checkAndRequestPermissionsForGPS(context)) {
if (ActivityCompat.checkSelfPermission(context, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(context, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
Toast.makeText(context, "First enable LOCATION ACCESS in settings.", Toast.LENGTH_LONG).show();
return;
}
boolean isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
if (isGPSEnabled) {
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
locationManager.requestSingleUpdate(criteria, new LocationListener() {
#Override
public void onLocationChanged(Location location) {
callback.onNewLocationAvailable(location);
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onProviderDisabled(String provider) {
}
}, null);
} else {
boolean isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (isNetworkEnabled) {
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_COARSE);
locationManager.requestSingleUpdate(criteria, new LocationListener() {
#Override
public void onLocationChanged(Location location) {
callback.onNewLocationAvailable(location);
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onProviderDisabled(String provider) {
}
}, null);
}
}
}
}
}
Now in you Activity import it like
import com.yourdomain.utils.SingleShotLocationProvider;
Now you can use it like below this is reference to your activity
SingleShotLocationProvider.requestSingleUpdate(this,
new SingleShotLocationProvider.LocationCallback() {
#Override
public void onNewLocationAvailable(Location location) {
if (location != null) {
double latitude = location.getLatitude();
double longitude = location.getLongitude();
}
}
}
});
You will receive location in first attempt just make sure GPS is on and set to high accuracy.And in manifest you have given necessary permission as like below -
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
Try this code. I am using the GPS here to get the latitude and longitude.
Criteria criteria = new Criteria();
// Getting the name of the best provider
provider = locationManager.getBestProvider(criteria, true);
// Getting Current Location
location = locationManager.getLastKnownLocation(provider);
if (location != null) {
System.out.println("Get Last LOcation" + location.getLatitude()
+ location.getLongitude());
loc.setLatitude(location.getLatitude());
loc.setLongitude(location.getLongitude());
}
locationListener = new LocationListener() {
#Override
public void onStatusChanged(String provider, int status,
Bundle extras) {
// TODO Auto-generated method stub
}
#Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
#Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
#Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
if (location.getAccuracy() < 50) {
locationManager.removeUpdates(locationListener);
}
}
};
locationManager.requestLocationUpdates(provider,
INTERVAL_TIME_SECONDS, MIN_DISTANCE_METERS,
locationListener);
I'm unable to send mock location on my real device. I've enabled Mock location in settings and disabled network location in Location settings.
Manifest:
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.VIBRATE"/>
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
Here is the code:
private static final String PROVIDER_NAME = "flp";
locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
locationManager.setTestProviderEnabled(PROVIDER_NAME, true);
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER, 1000, 1, new LocationListener() {
#Override
public void onLocationChanged(Location location) {
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onProviderDisabled(String provider) {
}
});
mockLocation(12.333, 13.444);
And this method:
public void mockLocation(double lat, double lng) {
// Create a new Location
Location newLocation = new Location(PROVIDER_NAME);
newLocation.setLatitude(lat);
newLocation.setLongitude(lng);
newLocation.setAccuracy(3.0f);
newLocation.setTime(1);
locationManager.setTestProviderLocation(PROVIDER_NAME, newLocation);
}
Why is onLocationChanged() not called?
This is what worked for me
locationManager.addTestProvider(mocLocationProvider, false, false,
false, false, true, true, true, 0, 5);
locationManager.setTestProviderEnabled(mocLocationProvider, true);
Location mockLocation = new Location(mocLocationProvider); // a string
mockLocation.setLatitude(location.getLatitude()); // double
mockLocation.setLongitude(location.getLongitude());
mockLocation.setAltitude(location.getAltitude());
mockLocation.setTime(System.currentTimeMillis());
locationManager.setTestProviderLocation( mocLocationProvider, mockLocation);
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION">
Also in the android phone settings make sure you have the "Allow mock locations" checkbox ticked.

getLastKnownLocation is allowed to return null. It means it hasn't recently figured out a location, or the location it has is so old it doesn't want to return it. You need to account for this possibility. That's one of the two reasons you need to be careful with getLastKnownLocation (the other being that even if it does return a value, it could be really wrong- as in hours old, there is no promise of freshness with it).
How to find user current location latitude,longitude without touch event?I searched in internet but i get latitude,longitude only touch event.
I've answered to similar question of yours here. Take a look at that. It doesn't need the google maps.
public class LocationSampleActivity extends Activity implements OnInitListener
{
TextView tv;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv = (TextView)this.findViewById(R.id.txtLocation);
tts = new TextToSpeech(this, this);
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
LocationListener ll = new mylocationlistener();
lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, ll);
}
private class mylocationlistener implements LocationListener
{
#Override
public void onLocationChanged(Location location) {
if (location != null) {
Log.d("LOCATION CHANGED", location.getLatitude() + "");
Log.d("LOCATION CHANGED", location.getLongitude() + "");
String str = "\n CurrentLocation: "+
"\n Latitude: "+ location.getLatitude() +
"\n Longitude: " + location.getLongitude();
tv.append(str);
speak(location);
}
}
#Override
public void onProviderDisabled(String provider) {
Toast.makeText(LocationSampleActivity.this,"Error onProviderDisabled",Toast.LENGTH_LONG).show();

}
}
It will update your current location's latitude & longtitude into the TextView without touch simply. Please add the important permission into your 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.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
use MyLocationOverlay for get current location.
MyLocationOverlay whereAmI = new MyLocationOverlay(this,mapview);
GeoPoint myLocationGeoPoint = whereAmI.getMyLocation();
float latitude = myLocationGeoPoint.getLatitudeE6() / 1E6;
float longitude = myLocationGeoPoint.getLongitudeE6() / 1E6;
I am using following code to get current latitude and longitude. But none of the toasts are displayed.
public void onCreate(Bundle savedInstanceState) {

Thanks for the help in advance
Sneha
GPS doesn't work in indoor mode..depending upon the place..It works perfectly on outdoor mode..So check it out outside..
GPS_PROVIDER is slow when compared to The NETWORK_PROVIDER.And in room it may not work.Switch on the GPS if you want to use GPS_PROVIDER. or else use NETWORK_PROVIDER.
Go through this
Note:Network_provider is not so accurate compared to the GPS_Provider.. But it is fast..
See this link also
#Sneha --
1) is this line printed Log.i("","loccccccccccc");
2) Check this
3) try to use criteria
4) Test this on mobile (Device) & also test it outside as GPS doesn't work inside.
