java – How to implement google places autocomplete programmatically

Questions:

Autocomplete predictions don’t show up in my MapsActivity when i type text in AutoCompleteTextView (mSearchText).

I tried following the tutorial at the following link: https://www.youtube.com/watch?v=6Trdd9EnmqY&list=PLgCYzUzKIBE-vInwQhGSdnbyJ62nixHCt&index=8.
Some methods used in it recently became deprecated, so I checked the documentation at https://developers.google.com/places/android-sdk/autocomplete, especially “Get place predictions programmatically” and “Migrating to the New Places SDK Client”. I also followed a guide from the same guy to set up my API key, and I think that shouldn’t be the problem here. This is my first Android application and my first question on this site, so please be patient with me.

    Places.initialize(getApplicationContext(), getString(R.string.google_maps_API_key));
    PlacesClient placesClient = Places.createClient(this);

    FindAutocompletePredictionsRequest request = FindAutocompletePredictionsRequest.builder()
            .setLocationBias(RECTANGULAR_BOUNDS)
            .setQuery(mSearchText.getText().toString())
            .build();

    placesClient.findAutocompletePredictions(request).addOnSuccessListener((response) -> {
        for (AutocompletePrediction prediction : response.getAutocompletePredictions()) {
            Log.i(TAG, prediction.getPlaceId());
            Log.i(TAG, prediction.getPrimaryText(null).toString());
        }
    }).addOnFailureListener((exception) -> {
        if (exception instanceof ApiException) {
            ApiException apiException = (ApiException) exception;
            Log.e(TAG, "Place not found: " + apiException.getStatusCode());
        }
    });

The Autocomplete predictions should show up as the user types in the searchbar, but that doesn’t happen. I don’t get any of the logs from the listeners either.
