I am using the below code to obtain the location of a user
public class MainLocation extends Application implements LocationListener {
protected LocationManager locationManager;
protected LocationListener locationListener;
protected Context context;
String lat;
String provider;
protected String latitude, longitude;
protected boolean gps_enabled, network_enabled;
#Override
public void onCreate() {
super.onCreate();
Log.e("Location", "here");
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// public void requestPermissions(#NonNull String[] permissions, int requestCode)
// 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 Activity#requestPermissions for more details.
return;
}
}
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
}
#Override
public void onLocationChanged(Location location) {
Log.e("Location", "" + location.getLatitude());
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.e("Location Status", "" + provider + " " + status + " " + extras);
}
#Override
public void onProviderEnabled(String provider) {
Log.e("Location", "Enabled");
}
#Override
public void onProviderDisabled(String provider) {
Log.e("Location","Disabled"+provider);
}
}
but here the onLocationChanged function is never getting called, so i m not able fetch the location. So how can i get the location?
In the logcat, the info tab is showing the latitude and longitude under the title onLocationReceived".

The Google Play services location APIs are preferred over the Android framework location APIs (android.location) as a way of adding location awareness to your app.
You can find the example how to use it right here.
P.S. Don't forget to check if permissions granted on your device, if you added permissions into manifest file...

Valid=FALSE Implies your device does not have a GPS lock. Is your device indoors and unable to obtain a position? Second, please check to see if your application has the positioning permission.
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

I have a problem with my GPS Location App I have tried by all means and I can't find the solution (I'm developing in Android 6.0) , this is the problem:
"network" location provider requires ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permission
this is my XML FIle:

Localizacion Local = new Localizacion();
Local.setMainActivity(this);
mlocManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,

return;
}
} else {
//simply use the required feature
//as the user has already granted permission to them during installation
}
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 1);

}
Please help, I took 2 days looking at internet solutions and nothing works for me
The steps that explains the problem I faced are below;
1. I start the android application.
2. I put it on backgorund by pressing home button.
3. I turn the screen off.
4. I turn the screen on after some seconds.
5. My application suddenly becomes foreground. I realised that the application is forced to start again and the application class that I used is created again and then the start page of my application (this is login page) is shown although what page is opened before the step 2.
What I have tried so far is below;
I put configChanges and screenOrientation in all the activiy tags in my Androidmanifest.xml (I tried to put them one by one and both together also.)
<activity android:configChanges="orientation|keyboardHidden|screenSize"
android:name="com.myproject.Activity"
android:screenOrientation="nosensor"/>
I also tried to use screenOrientation="portrait" but didn't work.
My problem is related with the How do I disable orientation change on Android?, Prevent Android activity from being recreated on turning screen off and like others, but I could not find the solution of my problem yet.
Can you please help?

Edit 3:****************
I use fragments, maybe this will be the reason, but I am not sure.
The problem is due to a library I used. It works in background and makes the application restarts.
I suspend it when the application goes to background and resume it when it comes foregorund. That is it, the problem is solved.
Thanks you anyway.
There are some questions regarding this issue but I could not find any method works without problem. I implemented the version of the project with GPS provider and now I want to implement a version which can find the location of user without GPS, just using network provider such as Wifi. I tried this but it is not working (I could not get the "done" message in any way):
public class MapsActivity extends FragmentActivity {
double latitude;
double longitude;
LocationManager locationManager;
android.location.LocationListener networkLocationListener;
Location location;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
networkLocationListener = new android.location.LocationListener() {
public void onLocationChanged(Location location) {
latitude = location.getLatitude();
longitude = location.getLongitude();
Log.d("->", "done.");
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
};
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, networkLocationListener);
}
...
Also, this is my manifest file:

Can you see the problem? What you advise at this point? Is there a better way?

- You can use GoogleclientAPi, as locationmanager has been
Deprecated
-Using FusedLocationAPi it will automatically discover the provider to find the location.
- https://developer.android.com/google/auth/api-client.html have a look
on this
- Here is one exampleprotected void createLocationRequest() {
LocationRequest mLocation = LocationRequest.create();
GoogleAPiClient mgoogle;
/*enter code here
* Set the update interval
*/
mLocation.setSmallestDisplacement(500); // 2km
mLocation.setInterval(180000);// 3 min
mLocationRequest.setFastestInterval(120000);// 2 min
mLocation.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
if (mgoogle == null) {
mgoogle = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API).addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).build();
mgoogle.connect();
}
}
It's a sample and implementing OnConnectionFailedListener,
ConnectionCallbacks, com.google.android.gms.location.LocationListener above 3 interfaces you can get the continuos Location.
getLastLocation Method Of LocationRequest Class will give you Location.
onLocationChanged Method will give you Your desired output.
You can use IP address of user for getting approx location.
