Exit App Ionic 5

Ionic Framework
1

Already tried :
App.exitApp(), navigator.app.exitApp(), navigator[‘app’].exitApp(), ionic.platform.exitApp()… doesn’t work

my code:

import { Injectable } from '@angular/core';
import { AlertController, NavController, Platform } from '@ionic/angular';
import { Router } from '@angular/router';
import { App } from '@capacitor/app';


@Injectable({
  providedIn: 'root'
})
export class BackButtonExitService {

  constructor(
    private platform: Platform,
    private router: Router,
    private navCtrl: NavController,
    private alertController: AlertController
  ) { }

  init(){
    this.platform.backButton.subscribeWithPriority(6666666666666666, async ()=>{
      const currentUrl = this.router.url;

      if(currentUrl === '/home'){

        const alert = await this.alertController.create({
          header: 'Quer Sair?',
          buttons: [
            {
              text: 'Não',
              role: 'cancel'
            },
            {
              text: 'Sim',
              role: 'confirm',
              handler: () => {
                window.close();
              },
            },
          ],
        });

        await alert.present();


      }else if(currentUrl === '/'){

        const alert = await this.alertController.create({
          header: 'Quer Sair?',
          buttons: [
            {
              text: 'Não',
              role: 'cancel'
            },
            {
              text: 'Sim',
              role: 'confirm',
              handler: () => {
                window.close();
              },
            },
          ],
        });

        await alert.present();

      }
      else{
        this.navCtrl.back();
      }
    })
  }
}

Are you trying this in Android or iOS? I don’t think you can exit the app programmatically on iOS.

Android, not working.
