I am trying to implement something similar to this (https://github.com/ankitsinghmyself/SearchNearByPlace) in my Android application. I have tried running the persons code straight from GitHub with my own API key and it works but will not allow Nearby Search.

I have tried two YouTube tutorials and two GitHub repos and no luck with Nearby Search. Can anyone please shed some light on why this is causing me issues?

I have Places and SDK API with billing account, and have added the correct dependencies etc. The map works fine with my current location, but the buttons will not show the nearby locations.

Here is what I have, it’s quite a lot, so if you need more information from me please ask:

MapsActivity:

    private GoogleMap mMap;

//    private MaterialSearchBar materialSearchBar;

    double latitude,longitude;

        mapFragment.getMapAsync(this);
        mapView = mapFragment.getView();

        mFusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(MapsActivity.this);
        Places.initialize(MapsActivity.this, getString(R.string.google_maps_key));
    }
