I am trying to use the Keycloak-js(from 4.4.0.Final) library in my ionic(4) cordova application. I have followed the example <https://github.com/keycloak/keycloak/tree/master/examples/cordova-native> and instructions <https://www.keycloak.org/docs/latest/securing_apps/index.html#_javascript... from the documentation. I have installed cordova-plugin-browsertab, cordova-plugin-deeplinks, cordova-plugin-inappbrowser. Added <preference name="AndroidLaunchMode" value="singleTask" /> in my config.xml And <widget id="org.phidatalab.radar_armt"....> <plugin name="cordova-plugin-browsertab" spec="0.2.0" /> <plugin name="cordova-plugin-inappbrowser" spec="3.0.0" /> <plugin name="cordova-plugin-deeplinks" spec="1.1.0" /> <preference name="AndroidLaunchMode" value="singleTask" /> <allow-intent href="http://*/*" /> <allow-intent href="https://*/*" /> <universal-links> <host name="keycloak-cordova-example.mydomain.net" scheme="https"> <path event="keycloak" url="/login" /> </host> </universal-links> </widget> and my service which uses Keycloak-js looks like below. static init(): Promise<any> { // Create a new Keycloak Client Instance let keycloakAuth: any = new Keycloak({ url: 'https://mydomain.net/auth/', realm: 'mighealth', clientId: 'armt', }); return new Promise((resolve, reject) => { keycloakAuth.init({ onLoad: 'login-required', adapter: 'cordova', responseMode: 'query', redirectUri: 'android-app://org.phidatalab.radar_armt/https/keycloak-cordova-example.github.io/login' }).success(() => { console.log("Success") resolve(); }).error((err) => { reject(err); }); }); } I can successfully build and run the application for android. However, it doesn't work. If I try to run it on browser, I get "universalLink is undefined". I would really like some help to get this working. What am I missing? Any kind of help is much appreciated.
