Hi,

I am using a loading controller during a http call. In android when I press hardware back button the page navigates back but loading controller is still displayed. What I want to disable hardware back button when loading controller is displaying.

Not a good solution but I register back button action before calling any http call using registerBackButtonAction function & deregister it in http response or error.

registerBackButtonAction(){
    this.unregBackCall = this.platform.registerBackButtonAction(() => {

    }, 100);
  }

  removebackbtnaction(){
    this.unregBackCall && this.unregBackCall();
  }

Ionic team should add disabling back button action while loading controller is showing.

Thanks
