Get location updates after GPS enabled by user

I have a simple App which currently simply asks for necessary permissions and in case GPS is OFF, you get an AlertDialog asking you if you want to switch it ON. After accepting, being taken to GPS options, enabling it, and going back to my App, I'd like to update location and here I get lost.
In other words, I'm trying to do what's stated here: https://stackoverflow.com/a/43396965/7060082
Unfortunately I can't manage to get it done and the example is a bit complicated for me to understand. Here is a piece of my code showing the relevant bits:
private void checkGPS() {
manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if (!manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage(R.string.GPS_error)
.setCancelable(false)
.setPositiveButton(R.string.confirm, new DialogInterface.OnClickListener() {
public void onClick(#SuppressWarnings("unused") final DialogInterface dialog, #SuppressWarnings("unused") final int id) {
Intent gps = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivityForResult(gps, 1);
getLatLon();
}
})
.setNegativeButton(R.string.deny, new DialogInterface.OnClickListener() {
public void onClick(final DialogInterface dialog, #SuppressWarnings("unused") final int id) {
dialog.cancel();
}
});
final AlertDialog alert = builder.create();
alert.show();
} else {
getLatLon();
}
}
private void getLatLon() {
//manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
String provider = manager.getBestProvider(criteria, false);
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
manager.getLastKnownLocation(provider);
if (location != null) {
Toast.makeText(this, "This is my location: " + location.getLongitude() + ", " + location.getLatitude(), Toast.LENGTH_SHORT).show();
} else {
// manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
manager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
//location = manager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
/*
double longitude = location.getLongitude();
double latitude = location.getLatitude();
Toast.makeText(this, "This is my location: " + longitude + ", " + latitude, Toast.LENGTH_SHORT).show();
*/
}
}
}
#Override
public void onLocationChanged(Location l) {
location = l;
double longitude = location.getLongitude();
double latitude = location.getLatitude();
Toast.makeText(this, "This is my location: " + longitude + ", " + latitude, Toast.LENGTH_SHORT).show();
}
After asking for ACCESS_FINE_LOCATION permission (which is also stated on the manifest) I call checkGPS(). As said before, let's you enable or not the GPS. If enabled, I call getLatLon(). If there is a lastKnownLocation, good, if not...
Here I get lost. I call requestLocationUpdates and then do nothing waiting for onLocationChanged to recieve a location update and execute the rest of the code. Am I doing it right? The result is me clicking the button, switching GPS on. Click on the button again and nothing happens.
Any help with this will help.
Many thanks for your time.

I've developed fused location api demo application and utility pack here.
General Utilities
Try it if useful for you. To get location using fused location api, you just have to write following snippet...
new LocationHandler(this)
.setLocationListener(new LocationListener() {
#Override
public void onLocationChanged(Location location) {
// Get the best known location
}
}).start();
And if you want to customise it, simply find documentation here...
https://github.com/abhishek-tm/general-utilities-android/wiki/Location-Handler
I've written a sample code according to your need, this will handle GPS enable/disable dialog internally, try this one...
import android.content.Intent;
import android.location.Location;
import android.os.Bundle;
import android.support.v4.app.FragmentManager;
import android.support.v7.app.AppCompatActivity;
import com.google.android.gms.location.LocationListener;
import com.google.android.gms.location.LocationRequest;
import com.google.android.gms.maps.CameraUpdateFactory;

import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;

public class MainActivity extends AppCompatActivity implements OnMapReadyCallback, LocationListener {
private GoogleMap map;
private Marker marker;
private LocationHandler locationHandler;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Obtaining an instance of map
FragmentManager manager = getSupportFragmentManager();
SupportMapFragment mapFragment = (SupportMapFragment) manager.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
this.locationHandler = new LocationHandler(this)
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
.setInterval(5000)
.setFastestInterval(10000)
.setLocationListener(this);
}
#Override
public void onMapReady(GoogleMap map) {
this.map = map;
this.locationHandler.start();
}
#Override
public void onLocationChanged(Location location) {
LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
if (marker == null) {
marker = MapUtils.addMarker(map, latLng, R.drawable.ic_current_location);
map.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng, 14), 500, null);
} else {
marker.setPosition(latLng);
}
}
#Override
protected void onDestroy() {
super.onDestroy();
if (locationHandler != null) {
locationHandler.stop();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == LocationHandler.REQUEST_LOCATION) {
locationHandler.start();
}
}
}
Hope it will help you.

Your current code doesn't wait for the user to make a choice before calling getLatLon() in the case where GPS is disabled.
You will need to add a onActivityResult() override that will be called when the user goes back to your app.
First, remove the call to getLatLon() in the checkGPS() method for the case where GPS is disabled:
private void checkGPS() {
manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if (!manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage(R.string.GPS_error)
.setCancelable(false)
.setPositiveButton(R.string.confirm, new DialogInterface.OnClickListener() {
public void onClick(#SuppressWarnings("unused") final DialogInterface dialog, #SuppressWarnings("unused") final int id) {
Intent gps = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivityForResult(gps, 1);
//Remove this:
//getLatLon();
}
})
.setNegativeButton(R.string.deny, new DialogInterface.OnClickListener() {
public void onClick(final DialogInterface dialog, #SuppressWarnings("unused") final int id) {
dialog.cancel();
}
});
final AlertDialog alert = builder.create();
alert.show();
} else {
getLatLon();
}
}
Then, add the onActivityResult() override, check the setting again, and if it's now enabled then call getLatLon():
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
getLatLon();
}
}

after some time busy with other projects, got back to this one and I removed the getLatLon(); function from the checkGPS(); function and that's it, code is fine. I was using the emulator to check if this was working, but I forgot that the emulator has a fixed value for the latitude and longitude, so you get no updates like a real mobile phone, and thus it looked as if it was not working properly.
Sort of a newby mistake. Regardless, thanks for your offers. Was interesting looking at different ways of doing the same thing.

Use custom buttons on a service class

I have created a custom layout for my alertdiaog : alertdialog.setView(inflater.inflate(R.layout.custom_gps,null));
I want to replace the default Ok and cancel buttons with my buttons, since it's not possible to use findViewById in a service class, I wanted to know if there is a workaround to handle the clicks on my custom buttons.
I took a look at some old questions but i did not find (yet) any trick to make that happen. Can you guys help ?
I have another workaround on my mind, and it is to extend Activity instead of Service (whice will make findViewByID available, but what changes do i have to apply on my class to start a Service from an activity ?
Any help or indication is welcome !

You can create a simple class in which you have a method which show the dialog and you need to call that method very simple.ex-
public class AlertDialog {
public static void showdialog(Context context) {
// custom dialog
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.custom);
dialog.setTitle("Title...");
// set the custom dialog components - text, image and button
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("Android custom dialog example!");
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.ic_launcher);
Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
// if button is clicked, close the custom dialog
dialogButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
}
}
now in your service you can directly call this method by passing the context.
like-
AlertDialog.showdialog(context);

Location Listener Can't Reach Location

My app uses users location and have fragments. In main activity this fragments changes.
But there is a problem here. I implement "Location Listener" interface to my fragment class, and drop the breakpoint in "onLocationChanged" event. And program never hit the breakpoint.
Why I can not reach the users location?
Here is my code:
public class NearestCoffeeVenueFragment extends Fragment implements LocationListener{
// GPS Variables
private LocationManager locationManager;
private Location lastLocation;
private String provider;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
locationManager = (LocationManager)getActivity().getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,0,0,this);
provider = LocationManager.NETWORK_PROVIDER;
Location location = locationManager.getLastKnownLocation(provider);
if(location != null){
lastLocation = location;
Toast.makeText(getActivity(), getString(R.string.gps_success), Toast.LENGTH_SHORT).show();
}
else{
Toast.makeText(getActivity(),getString(R.string.gps_fail),Toast.LENGTH_SHORT).show();
cannotReachGpsWarning();
}
return inflater.inflate(R.layout.fragment_nearest_coffee_venue, container, false);
}
/** LocationListener Interface Functions
* */
#Override
public void onLocationChanged(Location location){
Toast.makeText(getActivity(),"Long: "+location.getLongitude()+" Lat:"+location.getLatitude(),Toast.LENGTH_LONG).show();
lastLocation = location;
}
#Override
public void onStatusChanged(String provider,int status,Bundle extras){
}
#Override
public void onProviderEnabled(String provider){
Toast.makeText(getActivity(),getString(R.string.gps_enabled_provider)+provider,Toast.LENGTH_LONG).show();
}
#Override
public void onProviderDisabled(String provider){
Toast.makeText(getActivity(),getString(R.string.gps_disabled_provider)+provider,Toast.LENGTH_LONG).show();
}
/// warning messages and buttons setted from strings file.
private void cannotReachGpsWarning(){
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage(getString(R.string.gps_disabled))
.setCancelable(false)
.setPositiveButton(getString(R.string.gps_enable),
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
showGPSOptions();
}
});
builder.setNegativeButton(getString(R.string.gps_disable),
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
}
private void showGPSOptions(){
Intent gpsOptionsIntent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(gpsOptionsIntent);
}
As I say, I don't see any toasts or anything else. The fragment's doesn't hit the breakpoint on "onLocationChanged" function. This means fragment can't reach location. And when fragment starts, I see "Can not reach location" error even the phone's location was on.

Did you enable location in the device for both sources GPS ans NETWORK? Currently in your code your'e asking for network provider, if this provider is disabled the method getLastKnownLocation will return null.

gps doesnt turn off on app exit

the method startSightManagement() is called twice throug my program, so i have two location Manager objects.
private void startSightManagement() {
String locationService = Context.LOCATION_SERVICE;
locationManager = (LocationManager)getSystemService(locationService);
// Get the GPS provider and request location updates
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
criteria.setAltitudeRequired(false);
criteria.setBearingRequired(false);
criteria.setCostAllowed(true);
provider = locationManager.getBestProvider(criteria, true);
locationManager.requestLocationUpdates(provider, 2000, 2, this);
// Obtain last known location and update the UI accordingly
Location location = locationManager.getLastKnownLocation(provider);
updateWithNewLocation(location);
sightManager = new SightManager(this);
// Set up the first sight
setSight();
}
my onPause() Activity with removeUpdates(this)-->This only removes one instance, how do i remove the other one??
protected void onPause() {
myLocationOverlay.disableMyLocation();
locationManager.removeUpdates(this);
locationManager=null;
// TODO Auto-generated method stub
super.onPause();
//Shutdown TTS everytime when activity is paused(Tolga)
if (mTts != null) {
mTts.stop();
}
// Unregister the proximity intent receiver. This also prevents the app from
// leaking when it is closed.
if (proximityIntentReceiver!=null) {
unregisterReceiver(proximityIntentReceiver);
}
}
Second problem is: app crashes when gps isnt enabled on start and i click yes when asked if gps should be enabled. when i remove these two lines everything works fine:
locationManager.removeUpdates(this);
locationManager=null;
here is the buildAlert method if gps isnt enabled on start:
private void buildAlertMessageNoGps() {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("GPS ist deaktiviert. Standorteinstellungen anzeigen?")
.setCancelable(false)
.setPositiveButton("Ja", new DialogInterface.OnClickListener() {
public void onClick(final DialogInterface dialog, final int id) {
startActivityForResult(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS), ENABLE_GPS_SUB);
}
})
.setNegativeButton("Nein", new DialogInterface.OnClickListener() {
public void onClick(final DialogInterface dialog, final int id) {
dialog.cancel();
finish();
}
});
final AlertDialog alert = builder.create();
alert.show();
}

Setting GPS and waiting for enable

I have a problem with setting GPS service . I want to check if GPS is enable . If it is disable , it will display a dialog to user turn it on . The problem is it not wait for user enable GPS and get location .

And I have class to use it
public class RestaurantListFragment extends ListFragment {
private ArrayList<Restaurant> restaurants;
private SQLDataHelper dataHelper;
private GPSTracker gps;
private double UserLatitude;
private double UserLongitude;
private ProgressDialog progressBar;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.restaurant_list, null);
}
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
gps = new GPSTracker(getActivity());
UserLatitude = gps.getLatitude();
UserLongitude = gps.getLongitude();
Toast.makeText(getActivity(),UserLatitude + "|" + UserLongitude,Toast.LENGTH_SHORT).show();
dataHelper = new SQLDataHelper(getActivity(), "restaurantDB");
restaurants = new ArrayList<Restaurant>();
dataHelper.openDB();
Cursor cursor = dataHelper.query("Restaurant", new String[]{"Id", "ResName", "Logo", "Address", "Latitude", "Longitude"}, null
, null, null, null, null);
if (cursor.moveToFirst()) {
do {
Restaurant restaurant = new Restaurant();
restaurant.setId(cursor.getInt(0));
restaurant.setResName(cursor.getString(1));
restaurant.setLogo(cursor.getString(2));
restaurant.setAddress(cursor.getString(3));
restaurants.add(restaurant);
} while (cursor.moveToNext());
}
//Collections.sort(restaurants);
RestaurantAdapter restaurantAdapter = new RestaurantAdapter(getActivity(),restaurants);
setListAdapter(restaurantAdapter);
}
}
It works fine when GPS is enable . I want the user can turn it on first . After that it show user location . Then it can query database and setListAdapter . Thanks for any suggestion .
