[omarbakry]

App doesn’t closed when clicking on hardware back button. How can fix that?

You need to add handler for android back button to exit app:

Hardware back button with Ionic 4

import { Platform } from '@ionic/angular'; import { AppMinimize } from '@ionic-native/app-minimize/ngx'; ....// blah blah constructor( private platform: Platform,private appMinimize: AppMinimize) { this.platform.backButton.subscribe(()=>{ // navigator['app'].exitApp(); this.appMinimize.minimize(); }); } ....// blah blah Try the above code… Its working for me perfectly as the android home button works
