[SOLVED]Closing InAppBrowser restarts my app

Ionic Framework ionic-v3

After implementing lazy loading in my application i experience weird behaviour when using InAppBrowser.

I get an error, ‘Invalid event targets’, when trying to subscribe to InAppBrowser events. Just like in this post.

When i exit the inAppBrowser the app restarts.

I run the application on my android device, where the following code has done the job for me before.

public viewPdf(path: string):Promise<any>{
    return new Promise<any>((resolve, reject) => {
        if(this.platform.is('cordova')){
            this.loaderService.showLoader("Loading document...");
        }
            
        firebase.storage().ref().child(path).getDownloadURL().then(url => {
            let newURL = 'https://docs.google.com/viewer?&url=' + encodeURIComponent(url);
            this.browser = this.iab.create(newURL, '_blank', this.browserOptions);
              
            if(this.platform.is('cordova')){
               this.handleBrowserSubscriptions();
            }
            resolve();
        })
        .catch(err => {
            if(this.platform.is('cordova')){
                this.loaderService.dismissLoader();
            }
            reject(err);
        });
    })
}
private handleBrowserSubscriptions():void{
    let stopSub = this.browser.on('loadstop').subscribe(event => {
        this.loaderService.dismissLoader();
        stopSub.unsubscribe();
        errorSub.unsubscribe();
    });

    let exitSub = this.browser.on('exit').subscribe(event => {
        this.loaderService.dismissLoader();
        exitSub.unsubscribe();
        this.browser.close();
    });
        
    let errorSub = this.browser.on('loaderror').subscribe(event => {
        this.loaderService.dismissLoader();
        this.browser.close();
        stopSub.unsubscribe();
        errorSub.unsubscribe();
    });
}

After some hours googling this issue i have come up empty.
I would really appreciate if someone could help me out here.

At the time of implementing lazy loading i removed and added the android platform. So the simple solution was that the plugin was not installed. And therefore it fell back to window.open… (Facepalm…)
