 updateLicense1(){
    const fileTransfer: FileTransferObject = this.transfer.create();
    let headers = new Headers();
    let token = JSON.parse(localStorage.getItem('user'));
    headers.append('Authorization', token.token);
    let options: FileUploadOptions = {
      fileKey: 'file',
      fileName: "myImage.jpg",
      chunkedMode: false,
      httpMethod: 'post',
      mimeType: "multipart/form-data",
      headers: headers,
      params : {
        'evidenceOfOwnership' : this.evidenceOfOwnership,
        'license1' : this.base64Image,
        'license2' : this.base64Image2
      }
    }
    fileTransfer.upload(this.base64Image && this.base64Image2 , url, options)
      .then((data) => {
        console.log('ok');
      }, (err) => {
