Friends,
I have a code which open PDF document from base64 data, which work fine for Android 6.0.1 (2016 - Marshmellow) Samsung mobiles, 5.1 (Lolipop) Micromax mobile but not in 5.1.1 Lolipop Samsung device & 7.0 Nougat Lenovo device.

My working code is below:



    let downloadPDF: any = ‘W0JFR0lOXQolUERGLTEuMgp6R1/V+d9KpBi3sCNzNh…….’
    fetch(‘data:application/pdf;base64,’ + downloadPDF,
    {
    method: “GET”
    }).then(res => res.blob()).then(blob => {
    this.file.writeFile(this.file.externalApplicationStorageDirectory, ‘statement.pdf’, blob, { replace: true }).then(res => {
    this.fileOpener.open(
    res.toInternalURL(),
    ‘application/pdf’
    ).then((res) => {

              }).catch(err =&gt; {
                console.log(‘open error’)
              });
            }).catch(err =&gt; {
                  console.log(‘save error’)     
       });
          }).catch(err =&gt; {
                 console.log(‘error’)
          });

Why this happens ? In not working mobiles even that PDF not created . I hope this is a big issue of ionic 3.

Please advise

Thanks
