Android StreetView checks if there is any view for a given location

Question

I just play with the new StreetView function for Google Play Services 4.4 for Android ( link ), and I was wondering if there is any method / ability to check if there is any “view” / foto material for any given location. When I load a location that StreetView does not cover with, streetViewPanorama.setPosition(someLatLng); I just get a black screen. Any way to check in advance?

Answer 1

A black screen appears when the location is missing. Just check if it has been downloaded or not.

@Override
public void onStreetViewPanoramaReady(StreetViewPanorama streetViewPanorama) {
    mPanorama.setOnStreetViewPanoramaChangeListener(new StreetViewPanorama.OnStreetViewPanoramaChangeListener() {
        @Override
        public void onStreetViewPanoramaChange(StreetViewPanoramaLocation streetViewPanoramaLocation) {
            if (streetViewPanoramaLocation != null && streetViewPanoramaLocation.links != null) {
                // location is present
            } else {
                // location not available
            }
        }
    });

Answer 2

@Override
public void onStreetViewPanoramaReady(StreetViewPanorama streetViewPanorama) {
mPanorama.setOnStreetViewPanoramaChangeListener(new StreetViewPanorama.OnStreetViewPanoramaChangeListener() {
    @Override
    public void onStreetViewPanoramaChange(StreetViewPanoramaLocation streetViewPanoramaLocation) {
        if (streetViewPanoramaLocation != null && streetViewPanoramaLocation.links != null) {
            // location is present
        } else {
            // location not available
        }
    }
});

StreetViewPanoramaLocation location = mSvp.getLocation();
if (location != null && location.links != null) {
    mSvp.setPosition(location.links[0].panoId);
}
