Ionic 3 InAppBrowser not firing event - ionic-framework

Question

I am making an ionic app where I need to call to a website(not exist). I am just trying to catch that into the error. But the "exit" event does not get fired.
Code
this.browser = this.iab.create("http://www.randomwebsite.com/", "_blank", this.options);
this.browser.on('exit').subscribe(event => {
console.log("exit -->", event);
}, err => {
console.log("InAppBrowser exit Event Error: " + err);
});
It opens the browser in the app but only shows the 404 page, but dont go further in the error code, so that I can handle it.

Answer 1

Declare cordova in your component
declare var cordova;
Then for the error check you can use the following function
const browser = cordova.InAppBrowser.open('http://randomwebsite.org', '_blank', this.options);
browser.addEventListener('loadstart', function(e) {
// event fires when the InAppBrowser starts to load a URL.
console.log(e);
});
browser.addEventListener('loaderror', function(e) {
// event fires when the InAppBrowser encounters an error when loading a URL.
console.log(e);
browser.close();
});
You can checkout the documentation here.

Answer 2

If I understand the question correctly then the main problem is to catch the error
this.browser = this.iab.create("http://www.randomwebsite.com/", "_blank", this.options);
this.browser.on('loadstop').subscribe(event => {
console.log("exit -->", event);
}, err => {
//once the page loading stops and there is an error it comes here and displays you log.
console.log("InAppBrowser exit Event Error: " + err);
});
exit event is fired when we exit the inAppBrowser
