From my app, I'm trying to check if another app is installed (in my example, Google Maps). So I tried to use:

Linking.canOpenURL('comgooglemaps://?daddr=' + address + '&directionsmode=walking').then(supported => {...}).catch(err => console.error('An error occurred', err));

But it returns that it's not supported so it's like Google Maps is not installed. Do you know a way to solve this issue?

I'm assuming you're having this problem with iOS.

Starting with iOS 9, you have to declare the URL scheme you want to use. See this other answer with the details.

Or the official doc: https://developers.google.com/maps/documentation/ios-sdk/start#step_7_declare_the_url_schemes_used_by_the_api
