Sujan12, good day !

import { App} from 'ionic-angular';

  let navig = this.app.getActiveNav();
      if (navig.canGoBack()) {
        if (this.updateNewProvider.updateInProgress) {
          this.ConfirmExit();
        } else {
          if (this.confirm != undefined){
            this.confirm.dismiss();
            navig.pop();
          }else {
            navig.pop();
          }
        }

Do you also define app in the constructor to be of type App?
What do you get on console.log(this.app) before let navig?

getActiveNav() was deleted in Ionic 3.5.2

in my case I replaced the code with getRootNav() which is unfortunately marked as deprecated (I don’t use tabs)

P.S.: About this deprecation getRootNav() deprecated, use getRootNavById(): what's the value of the root nav id?

Hi all,

Whoops, I am really sorry about that. We should not have deleted this method. I think I must have been using the refactoring tools in VS Code and that’s why I didn’t notice. I will put this back in and release a patch today.

Once again I’m very sorry.

Thanks,
Dan
