Android API not sending post request

Ionic Framework ionic-v3
#1

Hello

My ionic app is working great on all api, except android api 29.

When clicking on a button, their is no post request is being send at all

postData(credentials, type) {
    return new Promise((resolve, reject) => {
      let headers = new Headers();

      this.http.post(apiUrl + type, JSON.stringify(credentials), {headers: headers})
        .subscribe(res => {
          resolve(res.json());
        }, (err) => {
          reject(err);
        });
    });

  }
