      correctOrientation: true,
      saveToPhotoAlbum: true,
      cameraDirection: this.camera.Direction.BACK
    };

    this.camera.getPicture(cameraOptions).then(image => {
      this.onUploadPicture(image);
    }, error => {
      console.log(error);
    });
  }

  onUploadPicture(fileURI: string) {
    const fileTransferObject: FileTransferObject = this.fileTransfer.create();

    const fileUploadOptions: FileUploadOptions = {

    let url: string = 'https://sm.ms/api/upload?smfile=' + fileURI;

    fileTransferObject.upload(fileURI, url, fileUploadOptions).then(data => {
      console.log(data["response"]);
      wilddog.auth().onAuthStateChanged(user => {
        user.updateProfile({'photoURL': JSON.parse(data["response"])["data"]["url"]}).then(() => {
          this.getUserData();
        }, error => {
          this.presentToast(error.name + ': ' + error.message);
        });
      });
    }, error => {
