The what3words mobile apps on Android and on iOS support the ability to allow your mobile app to send the user to the what3words app. You can either open the what3words app at the user’s current location or navigate directly to a 3 word address.
In your Android app, you can create a request to send the user to the what3words app using an
Uri address = Uri.parse("w3w://show?threewords=index.home.raft"); Intent navigate = new Intent(Intent.ACTION_VIEW, address);
In your iOS app, you can create a request to send the user to the what3words app using a URL scheme for inter-app communication.
NSURL *myURL = [NSURL URLWithString:@"w3w://show?threewords=index.home.raft"]; [[UIApplication sharedApplication] openURL:myURL]
[word.word.word]with a 3 word address and omitting the square brackets.
