What should I replace with my deprecated code?

Question

I have a code to get the current location of the user but some parts of the code says that it is deprecated

I tried copying other latest code but I also encountered some problems: Google maps does not get the user location if the user does not have a recent location

Then I tried reverting back to my old code though it is still working but I am quite worried that it may stop working at some point. Is there any code that I can replace with the deprecated code or latest codes that have the same function. I would greatly appreciate any insights or suggestions you might have. Thank you in advance for your help!

The codes that I replace it with is

  locationRequest = new LocationRequest.Builder(Priority.PRIORITY_HIGH_ACCURACY, 100)
                .setWaitForAccurateLocation(false)
                .setMinUpdateIntervalMillis(2000)
                .setMaxUpdateDelayMillis(100)
                .build();

The old deprecated code is

locationRequest = LocationRequest.create();
        locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        locationRequest.setInterval(5000);
