Get Location form GPS and set marker on google maps in android

Question

Hi I am trying to getting location(latitude and longitude) from Gps and set marker on google map but it is not working.In this code I am trying to get latitude and longitude from gps Location Listener method onLocationChanged but this method never calling not showing any toast.

public class MapsFragment extends Fragment implements OnMapReadyCallback, GoogleMap.OnMapLoadedCallback {
    private static View view;
    private SupportMapFragment mMap;
    private static Double latitude = 28.6538100, longitude = 77.2289700;
    GoogleMap gMap;
    private static final int PERMISSION_REQUEST_CODE = 1;
    private MinDisLocationListener locationListener;
    private LocationManager lm;

    public MapsFragment() {
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        FragmentManager fm = getActivity().getSupportFragmentManager();
        SupportMapFragment mMapFragment = (SupportMapFragment) getActivity()
                .getSupportFragmentManager().findFragmentById(R.id.map);
        locationListener = new MinDisLocationListener();
        lm = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);
        if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION)
                == PackageManager.PERMISSION_GRANTED) {
            lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 5000, 2, this.locationListener);
        } else {
            requestPermission();
        }
        lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 5000, 2, this.locationListener);
        if (mMapFragment == null) {
            mMapFragment = SupportMapFragment.newInstance();
            fm.beginTransaction().replace(R.id.map, mMapFragment).commit();
            mMapFragment.getMapAsync(this);

Answer 1

Your code works perfect. You just have to move your device in the place where gps is available, because the place where you are testing your app may not have exposure to GPS satellite. onLocationChanged() will be called once GPS is detected by the device

Answer 2

Check your project from there http://www.androidhive.info/2012/07/android-gps-location-manager-tutorial But i think problem with manifest Have you this

<permission         android:name="tj.tajdev.mrking.whatisonindushanbe.permission.MAPS_RECEIVE"         android:protectionLevel="signature" />     <uses-feature         android:glEsVersion="0x00020000"         android:required="true" />     <uses-permission android:name="android.permission.VIBRATE" />     <uses-permission android:name="tj.tajdev.mrking.whatisonindushanbe.permission.MAPS_RECEIVE" />     <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />     <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_NETWORK_STATE" />     <uses-permission android:name="android.permission.READ_PHONE_STATE" />     <uses-permission android:name="android.permission.INTERNET" />     <uses-permission android:name="android.permission.RECORD_AUDIO" />     <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />     <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

And this

<meta-data             android:name="com.google.android.gms.version"             android:value="@integer/google_play_services_version" />
