Got some strange thing here while doing task of map rotation around user current location marker. So what i am trying to do is like google maps application on second "Current location" tap. Marker must keep its position at map center while map is moving.
As i understood need to use bearing value to update camera position object on GoogleMap v2.
CameraUpdate cameraUpdatePos;
CameraPosition.Builder currentPlaceBuilder = new CameraPosition.Builder().target(loc);
if (location.hasBearing())
currentPlaceBuilder.bearing(location.getBearing());
cameraUpdatePos = CameraUpdateFactory.newCameraPosition(currentPlaceBuilder.build());
map.animateCamera(cameraUpdatePos);
The bug is about every location returns every time false hasBearing() call result and bearing 0.0 with my app. But google maps app shows me my direction at this time properly.
I am using service
LocationManager manager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
googleApiClient = new GoogleApiClient.Builder(context)
.addConnectionCallbacks(gmsCallbacks)
.addOnConnectionFailedListener(gmsCallbacks)
.addApi(LocationServices.API)
.build();
locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
.setInterval(25 * 1000)
.setFastestInterval(5 * 1000)
.setSmallestDisplacement(1);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest)
.setAlwaysShow(true);`
and method onconnected
`#Override
public void onConnected(#Nullable Bundle bundle) {
if (ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
&& ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)
return;
Log.i(TAG, "Connected");
location = LocationServices.FusedLocationApi.getLastLocation(googleApiClient);
LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, locationRequest, gmsCallbacks);
if (locationChangeCallback != null)
locationChangeCallback.onLocationChanged(location);
}`
Does anybody knows how google map made their bearing calculation for auto orientation map mode ?
Maybe someone has such situation and could help me with advice. Thanks.

I have an Application in which,I get the user current location and add the marker on a Current location and it's perfectly works but i have some lat and lon and i want to show on map with Marker
Lat,Lon is in workshopList
My code :

} else {
//Request Location Permission

}
}
else {
buildGoogleApiClient();
mGoogleMap.setMyLocationEnabled(true);
}
}
protected synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(this)

.addOnConnectionFailedListener(this)

#Override

//move map camera

if (mGoogleApiClient != null) {
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
}
}
private void fetchServiceProviders()
{
//volley call and populate in list
}
}
you can simply use this method:
#Override
public void onMapReady(GoogleMap map) {
for(ServiceProviderItem item : workshopList){
map.addMarker(new MarkerOptions()
.position(new LatLng(item.lat, item.lng))
.title("Hello world"));
}
}
try this:
private GoogleMap googleMap;
private MarkerOptions options = new MarkerOptions();
private ArrayList<LatLng> latlngs = new ArrayList<>(); //define arraylist of latlng
you can add lat long to the Arraylist using
latlngs.add(new LatLng(21.334343, 92.43434));
Now for showing them on Map use a for loop
for (LatLng point : latlngs) {
options.position(point);
options.title("Marker Title");
options.snippet("Marker Desc");
googleMap.addMarker(options);
}
I developed an application for Android in Eclipse with Google maps. The problem is that the blue dot indicating my current location appears always parallel to the road where I am driving, on roads outside cities. But if you are within the city the point already on top of the road.
I'm using this to get my location on the start of the app:
locationManager = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
Location myLocation = locationManager.getLastKnownLocation(locationManager.getBestProvider(criteria, false));
then I add the blue dot to the map:
googleMap.setMyLocationEnabled(true);
and then I start listening for location changes:
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, time, 1, this);
My location change function:
#Override
public void onLocationChanged(Location location) {
if (location != null) {
Lat1 = location.getLatitude();
Long1 = location.getLongitude();
if (Lat1 != Lat || Long1 != Long) {
Lat = location.getLatitude();
Long = location.getLongitude();
if (startNav == true) {
googleMap.animateCamera(CameraUpdateFactory
.newLatLngZoom(new LatLng(location.getLatitude(), location.getLongitude()), 17));
b = new LatLng(Lat, Long);
if (a != null) {
String urlTopass = makeURL(b.latitude, b.longitude, a.latitude, a.longitude);
new connectAsyncTask(urlTopass).execute();
}
}
}
}
}
My question is why does the blue dot appear parallel to the street instead of on top of it?
Use the FusedLocationProviderAPI. It is recommended over using the older open source Location APIs, especially since you're already using a Google Map so you are already using Google Play Services.
Simply set up a Location Listener, and update your current location Marker in each onLocationChanged() callback. If you only want one location update, just un-register for callbacks after the first callback returns.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

buildGoogleApiClient();
mGoogleApiClient.connect();
}
if (map == null) {

.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
}
#Override

public void setUpMap(){

map.setMyLocationEnabled(true);
}

#Override

mLocationRequest.setInterval(1000);
mLocationRequest.setFastestInterval(1000);
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
//mLocationRequest.setSmallestDisplacement(0.1F);
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
}
#Override

}
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
}
#Override
public void onLocationChanged(Location location) {
mLastLocation = location;
//remove previous current location Marker
if (marker != null){
marker.remove();
}
double dLatitude = mLastLocation.getLatitude();
double dLongitude = mLastLocation.getLongitude();
marker = map.addMarker(new MarkerOptions().position(new LatLng(dLatitude, dLongitude))
.title("My Location").icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_RED)));
map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(dLatitude, dLongitude), 8));
}
}
I´ve found some methods to do that but are deprecated or doesn´t work. I would like to get current latitude and longitude from device.
Here is how I'm getting the current location, but the GoogleMap getMyLocation() method is deprecated:
void getCurrentLocation()
{
Location myLocation = map.getMyLocation();
if(myLocation!=null)
{
double dLatitude = myLocation.getLatitude();
double dLongitude = myLocation.getLongitude();
map.addMarker(new MarkerOptions().position(new LatLng(dLatitude, dLongitude))
.title("My Location").icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_RED)));
map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(dLatitude, dLongitude), 8));
}
else
{
Toast.makeText(this, "Unable to fetch the current location", Toast.LENGTH_SHORT).show();
}
}

It's actually quite simple, using the FusedLocationProviderAPI is recommended over using the older open source Location APIs, especially since you're already using a Google Map so you are already using Google Play Services.

I am using below code to show current location on google maps. But the problem is that if i am moving my location is updating again and again. For the first time loading i want to fix my current location on the map, after that if i am moving then i don't want to update it. I am selecting a point on the map, and if i am moving or after few seconds it again moves to my current location and don't allow user to select desired point. My code is given below, please help me out here.
MarkerOptions markerOptions = new MarkerOptions();
private GoogleMap mMap;
private Location lastLocation = null;
private LocationClient mLocationClient;
LocationListener locationListener = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
float diff = 0;
if (lastLocation != null) {
diff = location.distanceTo(lastLocation);
}
if ((lastLocation == null) || (diff > 5)) {
LatLng latLng = new LatLng(location.getLatitude(),
location.getLongitude());
CameraPosition cameraPosition = new CameraPosition(latLng, 20,
45, 0);
CameraUpdate cameraUpdate = CameraUpdateFactory
.newCameraPosition(cameraPosition);
mMap.animateCamera(cameraUpdate, 2000, null);
lastLocation = location;
}
}
};
