For Ionic 4 check out the config option described here: https://ionicframework.com/docs/angular/config
and I have applied hardwareBackButton : true inside my app.module.ts but it will not working in Android device .
Currently : Not exit the Android app on backPressButton pressed (remain on Home page).
Expected : App should be exit as default android app worked.
Thank you in advanced.
Hi. you can use the following event
By default Ionic apps do not exit when pressing the hardware back button. We have examples in the documentation for how to implement this logic into your application: https://ionicframework.com/docs/developing/hardware-back-button#exiting-the-app.
