Thank you all for your support!


we have helped you because you have done great and fantastic work, and will keep supporting you :heart_eyes:


Great implementation.

Just a small, possibly irrelevant question; but would it be more convenient to load an extension into the program rather than uploading actual HTML files into the program? Opening the file may be a bit tedious, but would it be more tedious than opening it through your extension?

Quick side note: this query comes from a person who has no experience in file management.

No, of course, I suggest the file way. But if in some circumstances, you cannot use the file but you have to load it via text blocks, an extension is the only way to go.

Great extension actually , at least you already have all your code inside and embedded in the apk and java code not in a separate HTML document in assets folder

I got a new phone (Andorid 11) and webviewer not loading html files from inner store. Sofar it worked well on older phones. Eg. http://localhost/mszamla.html not loading with "404. Not found" error.

You have to copy the HTML code and then use it for the content.

why the extension doesn't load JS code?

This is HTML and not JavaScript. Search the forum to see how to run JavaScript. There are lots of examples.

ok, I got it thanks
