E/AndroidRuntime: FATAL EXCEPTION: main at dalvik.system.NativeStart.main(Native Method) crash

Question

For Android using Android Studio 2.0 Here's my code

package com.innovapp.maptest;

import android.location.Location;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

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.
mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}

@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.setMyLocationEnabled(true);
Location myLocation = new Location(mMap.getMyLocation());

LatLng myLatLng = new LatLng(myLocation.getLatitude(),myLocation.getLongitude());
mMap.addMarker(new MarkerOptions().position(myLatLng).title("Your Location"+myLocation.getAccuracy()));
mMap.moveCamera(CameraUpdateFactory.newLatLng(myLatLng));
}
}

Here's my stack trace

Can anyone help me figure out why I'm getting this exception?

Also

As I understand, getMyLocation() decrepated, so what should I use now that retains the functionality of my code?

Map.getMyLocation() can return null so you should check it first before calling getLatitude(). Also as you're using a map I would recommend you to implement onLocationChangeListener and initialize your map inside of this method

use

 MapsActivity extends FragmentActivity implements OnMapReadyCallback,
        GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener,
        LocationListener{}

OnCreate write

MapFragment mapFragment = (MapFragment) getFragmentManager()
                .findFragmentById(R.id.idMap);
        mapFragment.getMapAsync(context);

Check this
