Pdfmake: open() not working on Android

[girish-fuluskar]

Hi,

I am using PDFMake in my assignment, its working as expected (on android device and on laptop) and like to thank you for this.
However, Download() method not working on android devices.
My requirement is, after I show the PDF, pdfMake.createPdf(documentDefination).open(), I want to download same pdf to my android device and for this I am using pdfMake.createPdf(documentDefination).downlaod("test.pdf"). Its working fine on chrome but not on physical android device.
Does it save the PDF some other location on device or how I can achieve this?

any news on this, downloading is not working on android devices, and also opening, opens a new blank tab

I found a workaround, and it's working seamlessly both on android and ios.

const doc = pdfMake.createPdf(docDefinition); doc.getBase64((data) => { window.location.href = 'data:application/pdf;base64,' + data; });

Hope this helps

@marcomessa You helped me a lot! Tks!

[marcomessa]

You are welcome!

Be aware that this solution is gonna be deprecated in future Chrome versions!
But for now is a nice workaround!

Resource interpreted as Document but transferred with MIME type application/pdf

Also No new window is opening in chrome.Can u suggest any solutions

Chrome on Android throws error after download pdf file - "download failed due to unknown error":

• Chrome on Android 6.x, works without error
• Chrome on Andorid 7.x, throw error, fixed in Chrome version 60+ (actual version is 63)

=> In actual Chrome versions works download() correctly in Android 6 and 7.

someone find a solution? I'm building a cordova app and .download() don't work on devices.

Below code(Ionic) is works for me, tested on Android/iOS/Browsers.
[NOTE: I'm using [file opener plugin](https://github.com/pwlin/cordova-plugin-file-opener2) to open PDF.]

if (this.platform.is('cordova')) {
    // FOR MOBILE DEVICES
    pdfmake.createPdf(newdd).getBuffer((buffer) => {
      var utf8 = new Uint8Array(buffer); // Convert to UTF-8...
      let binaryArray = utf8.buffer; // Convert to Binary...

      let dirPath = "";
      if (this.platform.is('android')) {
        dirPath = this.file.externalRootDirectory;
      } else if (this.platform.is('ios')) {
        dirPath = this.file.documentsDirectory;
      }

      let dirName = 'DailySheet';

      this.file.createDir(dirPath, dirName, true).then((dirEntry) => {
        let saveDir = dirPath + '/' + dirName + '/';
        this.file.createFile(saveDir, fileName, true).then((fileEntry) => {
          fileEntry.createWriter((fileWriter) => {
            fileWriter.onwriteend = () => {
              this.hideLoading();
              this.showReportAlert('Report downloaded', saveDir + fileName);
              this.fileOpener.open(saveDir + fileName, 'application/pdf')
                  .then(() => console.log('File is opened'))
                  .catch(e => console.log('Error openening file', e));
            };
            fileWriter.onerror = (e) => {
              this.hideLoading();
              this.showAlert('Cannot write report', e.toString());
            };
            fileWriter.write(binaryArray);
          });
        }).catch((error) => { this.hideLoading(); this.showAlert('Cannot create file', error); });
      }).catch((error) => { this.hideLoading(); this.showAlert('Cannot create folder', error); });
    }).catch((error) => { this.hideLoading(); this.showAlert('Error while creating pdf', error); });
  }
  else {
    //FOR BROWSERS
    pdfmake.createPdf(newdd).download(fileName);
    this.hideLoading();
  }

Android not support open pdf in browser, but open invokes dialog to open document.
