How to detect if Google StreetView is available in

Question

I'm making an app that uses the Google Street View Image API

I have no problem getting an image of the street view based on the address/coordinates

but - I want to detect if the specific address has a Street View image available (in order to show a different behavior for addresses that doesn't have it)

The only idea I got so far is to read the pixels of the returned image and detect whether this is the image the I got when there is no image available

Any other idea?

Thanks!

Answer 1

Google has an api endpoint where you can look up the metadata for a panorama/streetview:

https://maps.googleapis.com/maps/api/streetview/metadata?key=YOUR_API_KEY&location=STRING_ADDRESS_OR_LAT_LNG_COORDINATES

You can check the status property of the response.

Using google.maps.StreetViewService.getPanoramaByLocation( latlng, radius, callback()), you can check whether there is a streetview panorama. If there is a streetview panorama, then there must be an image of streetview.

You can refer the reference of google : https://developers.google.com/maps/documentation/javascript/reference#StreetViewService

Or refer to the example of StreetViewService : https://google-developers.appspot.com/maps/documentation/javascript/examples/streetview-service

  mStreetViewPanorama.setOnStreetViewPanoramaChangeListener(streetViewPanoramaLocation -> {
                if (streetViewPanoramaLocation != null && streetViewPanoramaLocation.links != null) {
                    Toast.makeText(StreetViewActivity.this, "StreetView Camera Found", Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(StreetViewActivity.this, "StreetView Camera not Found", Toast.LENGTH_SHORT).show();
                }
            });
