Little question: How can i catch an error on interApp if interApp is pointing to a non existing app (ex:Facebook)?

         var InterApp = require("FuseJS/InterApp");
            InterApp.on("receivedUri", function(uri) {
                console.log(uri);
            });
            InterApp.launchUri("fb://facewebmodal/f?href=https://www.facebook.com/fusetools/");

Looking at LaunchUri implementation, the answer is: you can’t.

Well, at least not directly. You could write some foreign code specifically for checking if an app is installed, something like in this stackoverflow answer. You can both extend the LaunchUri implementation in a local fuselibs checkout, or write a separate Uno module for that. I’d go for option two if I were you.
