Unable to get data from one activity to another activity Android

I am trying to the LatLng values from one activity to another, however I'm receiving null values on the other activity.

Activity 1

PlacesClient placesClient = Places.createClient(this);

    final AutocompleteSupportFragment autocompleteSupportFragment= (AutocompleteSupportFragment) getSupportFragmentManager().findFragmentById(R.id.autocomplete_fragment);

    autocompleteSupportFragment.setPlaceFields(Arrays.asList(Place.Field.ID,Place.Field.LAT_LNG, Place.Field.NAME));

    autocompleteSupportFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
        @Override
        public void onPlaceSelected(Place place) {
            
           final LatLng latLng= place.getLatLng();
            
           Toast.makeText(searchActivity.this, "Latitude"+latLng.latitude+ "" +"Longitude"+latLng.longitude, Toast.LENGTH_SHORT).show();

            //
              lat1 = latLng.latitude;
              long1 = latLng.longitude;
            Intent intent1= new Intent(getApplicationContext(), shortestRouteActivity.class);

            intent1.putExtra("lat1",lat1 ); intent1.putExtra("long1",long1);

            Log.i("Place Coordinates: " ,"Latitude :"+latLng.latitude+ "" +"Longitude :"+latLng.longitude);
        }

        @Override
        public void onError(Status status) {
            // TODO: Handle the error.
            Log.i( "An error occurred: " , ""+status);
        }
    });

Activity 2

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_shortest_route);

    Bundle bundle = getIntent().getExtras();
    double lat1 = bundle.getDouble("lat1");
    double long1 = bundle.getDouble("long1");


    Log.i("Lat 1 and Long 1 =", lat1 + " : " +long1);

}

Error

java.lang.NullPointerException: Attempt to invoke virtual method 'double android.os.BaseBundle.getDouble(java.lang.String)' on a null object reference
    at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2646)

I have tried all the other ways to the get the values but still unable to do so.

Any-kind of help is appreciated! Thankyou.

How are u initializing the 2nd activity? Where is your

startActivity(intent1);

Maybe you are creating the 2nd activity before getting those values.
