I have a map which is loading a current address from a server. I am using on MapReady, and before its initialized it loads the first location from the server and zooms to the location. I want the app to be reading the address from the server every 10 seconds, and mapping the location. I am stuck after on MapReady on how I can remove the previous marker add the new marker from values from the server and still zoom on the location, the tutorials I have read like this haven't been so helpful. Below is my on MapReady.
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getActivity(),
Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
mMap.setMyLocationEnabled(true);
mMap.setTrafficEnabled(true);
mMap.setIndoorEnabled(true);
mMap.setBuildingsEnabled(true);
mMap.getUiSettings().setZoomControlsEnabled(true);
LocationManager locationManager = (LocationManager) getContext().getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
geocoder = new Geocoder(getActivity());
try {
ArrayList<Address> current_adresses = (ArrayList<Address>) geocoder.getFromLocationName(current_location, 1);
for(Address add : current_adresses){
if (current_adresses != null) {//Controls to ensure it is right address such as country etc.
current_longitude = add.getLongitude();
current_latitude = add.getLatitude();
}
}
ArrayList<Address> to_adresses = (ArrayList<Address>) geocoder.getFromLocationName(destination, 1);
for(Address add : to_adresses){
if (to_adresses != null) {//Controls to ensure it is right address such as country etc.
to_longitude = add.getLongitude();
to_latitude = add.getLatitude();
}
}
} catch (IOException e) {
e.printStackTrace();
}
location = locationManager.getLastKnownLocation(locationManager.getBestProvider(criteria, false));
if (location != null)
{
mMap.addMarker(new MarkerOptions()
.position(new LatLng(current_latitude, current_longitude))
.title(first_name + ", " + vehicle)
.icon(BitmapDescriptorFactory.fromResource(R.drawable.pickup)));
mMap.addMarker(new MarkerOptions()
.position(new LatLng(to_latitude, to_longitude))
.title("Destination")
.icon(BitmapDescriptorFactory.fromResource(R.drawable.office_building)));
CameraPosition cameraPosition= new CameraPosition.Builder()
.target(getCenterCoordinate())
.zoom(13)
.build();
CameraUpdate camUpd3 = CameraUpdateFactory.newCameraPosition(cameraPosition);
mMap.animateCamera(camUpd3);
//AsyncTask to get new address
getTransporterLocation();
/**
*
* I want to set a timer with the AsyncTask inside,
*
* remove the previous marker, convert the new address to lat and long
*
* map the marker and zoom in
*
*/
}
}
