Hi Guys.

Great Post. I've managed to dowload a PDF file from a website with the following blocks:

I'm using this version of CustomWebView:

.

There are a couple of things I would like to ask you:

  • I only managed to dowload the file using "~". None of the other folders worked. I'm testing with an Android 10 phone.
  • How can I open the file after I've download it?
  • How can I load a webpage that has been packed with the APK? (With WebViewer I used "http://localhost/home.html".

Thanks!
Rui

I used the blocks below to run downloads in custom webviewer, but the file name is only named as the extension (.mp4). How do i make the right file name show?

Ciao ho seguito i tuoi consigli e se cambio la cartella in documents su alcuni siti funziona, solo a me servirebbe che funzionasse su questo sito https://www.regione.campania.it/regione/it/la-tua-campania/casa-di-vetro-smc2

È un sito istituzionale ma io non vado a modificare nulla semplicemente voglio che il sito lo apre nell'app e poi avere la possibilità di scaricare i documenti, che da browser normalmente riesco, invece attraverso customwebview non riesco, grazie mille.

Hello, I followed your advice and if I change the folder in the documents on some sites it works, only I would work on this website https://www.regione.campania.it/regione/it/la-tua-campania/casa-di-vetro-smc2

It is a website but I'm not going to change anything, simply, I want the site to open in the app, and then have the possibility to download documents from a web browser normally can't, however, through customwebview I can not, thank you very much.

hi vknow360,

so i have a web application that supports downloading reports via blob URL, where when the user clicks a button it will redirect to blob::http://mysite/report/245264363.

can this be handled with the following block? or is there another solution?

because i tried to use the block, the message "Runtime Error: Can not handle uri:: blob:http://mysite/report/245264363" appears

thanks for your help.

PDF and xls format reports, on the web side are handled with the jsPDF library.
