                }
            });
        }
    }
}




step-(2) use in Activity

globally declair-> LocationUtils locationUtils;

in declaire oncreate->  
locationUtils = new LocationUtils(OtpLoginActivity.this,this);
locationUtils.checkPermissionsAndGetLocation();

  step(3)outer of oncreate->
  @Override
    public void onLocationReceived(Location location) {
         latitude = location.getLatitude();
         longitude = location.getLongitude();
//        Toast.makeText(this, "Latitude: " + latitude + "\nLongitude: " + longitude, Toast.LENGTH_SHORT).show();

    }

    @Override
    public void onLocationPermissionDenied() {

        locationText.setText("Location permission denied.");
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        locationUtils.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }


    public class OtpHandler {


        public OtpHandler() {
        }

this is first step->>
class ko implement krna hoga implement keyword se upprr
implements LocationUtils.LocationUpdateListener
isss type se example k torr p->
@AndroidEntryPoint
public class OtpLoginActivity  extends BaseActivity<LoginViewModel, ActivityOtpLoginBinding> implements LocationUtils.LocationUpdateListener{
