Ionic 4 android 调用 function 后恢复时应用程序冻结

Question

I am developing and app which has feature of calling a number. When i click call button it goes to dial pad and when we cancel it by back button and resumes our app then it freezes and nothing happens wherever we touch on screen. Below code i have used on call button click.

Method 1:

window.open('tel:' + this.contactNo, '_system');

Method 2:

  this.callNumber.callNumber(this.contactNo, true)
      .then( (data) =>
      {
        console.trace("called callnumber ", data);
      })
      .catch( (error) =>
      {
        console.log('Error launching dialer',error);
      });

I have tried both methods but same result. Any help. Thanks in advance

Answer 1

so i tried to replicate the issue but don't have any success on doing so.

i followed the Ionic Call Number package, Call number From Ionic Framework This were my solution.

Component

 async openCallModal(){
    this.callNumber.callNumber("18001010101", true)
        .then(res => console.log('Launched dialer!', res))
        .catch(err => console.log('Error launching dialer', err));
  }

View / HTML

<ion-content>
  <ion-button (click)="openCallModal()" color="primary">Call</ion-button>
</ion-content>
