Ionic Capacitor Hardware Back Button Is Automatically Closing The App

My current setup is: @capacitor/core: 3.0.0, @ionic-native/core: 5.0.7 I'm trying to change the behavior of my app to not close the app, but go back in the navigation stack. To my

Solution 1:

So, I feel a bit dumb after realizing this, but it is because I had to run the below commands, because I apparently didn't update them when upgrading Capacitor a while back. Make sure all of your plugins are fully updated, yours may be different than mine.

npm install @capacitor/app
npx cap sync

Solution 2:

I had the same issue and I tried installing all the plugins like it says here

npm install @capacitor/app @capacitor/haptics @capacitor/keyboard @capacitor/status-bar

After I finished installing, I still got the error. Also my PushNotifications plugin was not working either.

My problem was I forgot to delete the OnCreate method from MainActivity.java. So if you still have the problem after installing the plugins, try to delete OnCreate method so your MainActivity.java looks like this:

 public class MainActivity extends BridgeActivity {}

See more here.

It also fixed my PushNotifications plugin.

If I understand it correctly, if you have any plugin that is not registered correctly, it will cause this kind of error. This answer also helped me.

Solution 3:

1. Install capacitor app.

   npm install @capacitor/app

2. Import it.

   import { App as CapacitorApp } from '@capacitor/app';

3. Add back listener if can go back then we can push to back or exit the app.

   CapacitorApp.addListener('backButton', ({canGoBack}) => {
     if(!canGoBack){
       CapacitorApp.exitApp();
     } else {
       window.history.back();
     }
   });
   

Solution 4:

You need to use below code to handle the Hardware back button in Ionic app:

//back button handle
//Registration of push in Android and Windows Phone
let lastTimeBackPress: number = 0;
let timePeriodToExit: number = 2000;

platform.registerBackButtonAction(() => {

    //Double check to exit app
    if (new Date().getTime() - lastTimeBackPress < timePeriodToExit) {
        //this.platform.exitApp(); //Exit from app

        this.appMinimize.minimize().then(() => {
            console.log('minimized successfully');
        });
    } else {

        this.toastCtrl.create({
            message: this.translate.instant('EXIT_APP_MESSAGE'),
            duration: 3000,
            position: 'bottom'
        }).present();

        lastTimeBackPress = new Date().getTime();
    }
});

Solution 5:

I have the same issue and adding @capacitor/app to my App worked for debugging puposes. The Problem is, when I build a release app, it still closes the app.

--- EDIT ---

I fixed the issue by building a completely new Ionic App (with the latest versions of everything) and then copying my code. I assume it really had something to do with the installed versions of the Ionic and Capacitor packages
