Current behavior:
I try to use navigator['app'].exipApp() to exit app,but nothing happend

Expected behavior:
do navigator['app'].exipApp() and exit app

Steps to reproduce:

Related code:

this.platform.backButton.subscribe(() => {
    if (this.router.isActive('/home', true)) {
        if (click_times === 0) {
            this.toastService.info('click again to exit app');
            click_times++;
            setTimeout(() => {
                click_times--;
            }, 2000);
        } else {
            try {
                //expect to exit app, but first time is nothing happend, second time catch error
                navigator['app'].exipApp();
            } catch (e) {
                console.log(e);
            }
        }
    } else {
        this.goBackService.goBack();
    }
});

Other information:
I use chrome://inspect/#devices to debug apk and find that at first time do the action navigator['app'].exipApp(),it has no error ,but nothing happend.
And when I do navigator['app'].exipApp() again ,the code catch error :

TypeError: navigator.app.exipApp is not a function

Also,I try to build release apk,and it doesn't work as before

Ionic info:

TypeError: navigator.app.exipApp is not a function

Try to use .exitApp(); instead of . exipApp() :)

Hi there,

Thanks for the issue. As @bastyen noted, it should be navigator['app'].exitApp() instead of navigator['app'].exipApp().

Additionally, this is not something that Ionic Framework manages, so I am going to close this issue. For further questions feel free to post on our forum or our slack.

Thanks for using Ionic!
