Get Current Location GMaps

Question

i tried a lot of "get current location" for android. But i think most of them are outdated, or i simply dont get it.

I DONT want to set a marker.addmarker(params..) i would like to use the blue default dot for my position on Gmaps. Here i've found somthing about that, but for my bad it also aint work.

Customize marker of myLocation Google Maps v2 Android

So in first line i need, my current Location with a Listener when my Location is updating. Im trying this right now (Testing on a real device). But myLocation is always =null.

    //get GMaps Fragment
    mMap = ((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();
    mMap.setMyLocationEnabled(true);    //activate Blue dot

    myLocation = mMap.getMyLocation();  //Testing, but not working = null

    //Trying with LocationManager
    locManager =(LocationManager)getSystemService(this.LOCATION_SERVICE);
    Criteria criteria = new Criteria();
    String provider = locManager.getBestProvider(criteria, true);

    myLocation = locManager.getLastKnownLocation(provider);
    if(myLocation != null){
        double lat = myLocation.getLatitude();
        double lon = myLocation.getLongitude();
    }

    locManager.requestLocationUpdates(provider, 1000, 0, new LocationListener() {
        @Override
        public void onLocationChanged(Location location) {
            myLocation = location;
        }

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {

        }

        @Override
        public void onProviderEnabled(String provider) {

        }

        @Override
        public void onProviderDisabled(String provider) {

        }
    });

Answer 1

Follow this http://www.androidhive.info/2012/07/android-gps-location-manager-tutorial/ . Then just place the latitude and longitude you get(using gps.getLatitude(), gps.getLongitude()) in your google map and it will show your current location.

Answer 2

Try this code, it is worked in my application:

private LocationManager locationManager;
private String provider;
double lat,lon;
 public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.locate);

        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
       locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 6000, 1, this);
        if ( !locationManager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
            gpsalert();
        }
        // Criteria to select location provider

        Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);

        if (location != null) {

            Toast.makeText(getApplicationContext(), "Provider is available", Toast.LENGTH_SHORT).show();

        } else {
            Toast.makeText(getApplicationContext(), "Provider is not available", Toast.LENGTH_SHORT).show();
        }
    }
@Override
public void onLocationChanged(Location location) {
    // TODO Auto-generated method stub

    String addr,city,country;
    lat=location.getLatitude();
    lon=location.getLongitude();

    //Toast.makeText(getApplicationContext(), "lat"+lat+"long"+lon, Toast.LENGTH_LONG).show();
    Geocoder geocoder;
    List<Address> addresses;
    geocoder = new Geocoder(this, Locale.getDefault());
    try {
        addresses = geocoder.getFromLocation(lat, lon, 1);

         addr = addresses.get(0).getAddressLine(0);
        city = addresses.get(0).getAddressLine(1);
         country = addresses.get(0).getAddressLine(2);
         t1.setText(addr+"\n"+city+"\n"+country);

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }



}

@Override
public void onProviderDisabled(String provider) {
    // TODO Auto-generated method stub
    //Toast.makeText(this, "Disabled provider " + provider, Toast.LENGTH_SHORT).show();
    //t1.setText("");
}

@Override
public void onProviderEnabled(String provider) {
    // TODO Auto-generated method stub
    //Toast.makeText(this, "Enabled provider " + provider, Toast.LENGTH_SHORT).show();
}

@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
    // TODO Auto-generated method stub

}
@Override
protected void onResume() {
    super.onResume();
    //locationManager.requestLocationUpdates(provider, 400, 1, this);
}
                                    // Remove LocationListener updates
@Override
protected void onPause() {
    super.onPause();
    //locationManager.removeUpdates(this);
}
public void gpsalert()
{
    final AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMessage("Your GPS seems to be disabled, do you want to enable it?")
           .setCancelable(false)
           .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
               public void onClick(@SuppressWarnings("unused") final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
                   startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
               }
           })
           .setNegativeButton("No", new DialogInterface.OnClickListener() {
               public void onClick(final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
                    dialog.cancel();
               }
           });
    final AlertDialog alert = builder.create();
    alert.show();
}
