InAppBrowser lost reference

Ionic Framework ionic-v3
1

Hello

I have to open a webapp in a hybrid application. I wanted to use an iframe but I can’t know which link the user has clicked.

If the link leaves the webapp, the chrome app must be lunched. So I use InAppBrowser and I listen to the startload event. If the link leaves the webapp: I do window.stop () and start chrome. But when the user come back into the application, the startload event no longer works.

Example: I’m browsing on Google if I click to the https://m.facebook.com/login link, chrome starts on https://www.facebook.com and when I come back into the application: I can’t see anymore logged events in chrome’s inspector.

My code:

import { Component } from '@angular/core';
import { Platform } from 'ionic-angular';
import { StatusBar, Splashscreen } from 'ionic-native';
import {InAppBrowser} from 'ionic-native';
import { TabsPage } from '../pages/tabs/tabs';


@Component({
  templateUrl: 'app.html'
})
export class MyApp {
  rootPage = TabsPage;
  browser;
  constructor(private platform: Platform) {
    platform.ready().then(() => {
      StatusBar.styleDefault();
      Splashscreen.hide();
      this.launch();
    });
  }
  launch() {
    this.platform.ready().then(() => {
        this.browser = new InAppBrowser('https://www.google.com', '_self','location=no,toolbar=no');
        
        this.browser.on("loadstart").subscribe(data => { 
          console.log("loadstart");
          console.log(data);
          if(data.url == "https://m.facebook.com/login/"){
            this.browser.executeScript({ code: 'window.stop();' });
            window.open('https://www.facebook.com','_system');
          }
        });

        this.browser.on("exit").subscribe(data => { 
          console.log("exit");
          this.platform.exitApp();
          console.log(data);
        });
      });
  }
}

My logs:
