How to display my location on Google Maps for Android API v2

Question

I ve looked high and low for an answer on this  and no one  in any forum question has been able to help  I ve searched through the tutorials  The API Guide says      The My Location button appears in the top right corner of the screen   only when the My Location layer is enabled    So I ve been looking for this My Location layer and have been unable to find anything  How do I show my location on a Google Map

Before enabling the My Location layer  you must request location permission from the user  This sample does not include a request for location permission    To simplify  in terms of lines of code  the request for the location permit can be made using the library EasyPermissions   Then following the example of the official documentation of The My Location Layer my code works as follows for all versions of Android that contain Google services    Create an activity that contains a map and implements the interfaces OnMyLocationClickListener y OnMyLocationButtonClickListener  Define in app build gradle implementation  pub devrel easypermissions 2 0 1  Forward results to EasyPermissions within method onRequestPermissionsResult    EasyPermissions onRequestPermissionsResult requestCode  permissions  grantResults  this   Request permission and operate according to the user s response with requestLocationPermission   Call requestLocationPermission   and set the listeners to onMapReady      MapsActivity java  public class MapsActivity extends FragmentActivity implements      OnMapReadyCallback      GoogleMap OnMyLocationClickListener      GoogleMap OnMyLocationButtonClickListener        private final int REQUEST LOCATION PERMISSION   1       private GoogleMap mMap        Override     protected void onCreate Bundle savedInstanceState            super onCreate savedInstanceState           setContentView R layout activity maps              Obtain the SupportMapFragment and get notified when the map is ready to be used          SupportMapFragment mapFragment    SupportMapFragment  getSupportFragmentManager                findFragmentById R id map           mapFragment getMapAsync this               Override     public void onMapReady GoogleMap googleMap            mMap   googleMap           requestLocationPermission            mMap setOnMyLocationButtonClickListener this           mMap setOnMyLocationClickListener this               Override     public void onRequestPermissionsResult int requestCode   NonNull String   permissions   NonNull int   grantResults            super onRequestPermissionsResult requestCode  permissions  grantResults              Forward results to EasyPermissions         EasyPermissions onRequestPermissionsResult requestCode  permissions  grantResults  this               SuppressLint  MissingPermission        AfterPermissionGranted REQUEST LOCATION PERMISSION      public void requestLocationPermission             String   perms    Manifest permission ACCESS FINE LOCATION           if EasyPermissions hasPermissions this  perms                 mMap setMyLocationEnabled true               Toast makeText this   Permission already granted   Toast LENGTH SHORT  show                      else               EasyPermissions requestPermissions this   Please grant the location permission   REQUEST LOCATION PERMISSION  perms                         Override     public boolean onMyLocationButtonClick             Toast makeText this   MyLocation button clicked   Toast LENGTH SHORT  show            return false              Override     public void onMyLocationClick  NonNull Location location            Toast makeText this   Current location  n    location  Toast LENGTH LONG  show              Source

The API Guide has it all wrong  really Google    With Maps API v2 you do not need to enable a layer to show yourself  there is a simple call to the GoogleMaps instance you created with your map   Google Documentation  The actual documentation that Google provides gives you your answer  You just need to   If you are using Kotlin     map is a GoogleMap object map isMyLocationEnabled   true     If you are using Java     map is a GoogleMap object map setMyLocationEnabled true     and watch the magic happen   Just make sure that you have location permission and requested it at runtime on API Level 23  M  or above

Call GoogleMap setMyLocationEnabled true  in your Activity  and add this 2 lines code in the Manifest    lt uses-permission android name  android permission ACCESS COARSE LOCATION    gt   lt uses-permission android name  android permission ACCESS FINE LOCATION    gt

From android 6 0 you need to check for user permission  if you want to use GoogleMap setMyLocationEnabled true  you will get Call requires permission which may be rejected by user error  if  ContextCompat checkSelfPermission this  Manifest permission ACCESS FINE LOCATION                 PackageManager PERMISSION GRANTED       mMap setMyLocationEnabled true     else      Show rationale and request permission      if you want to read more  check google map docs
