B4J Tutorial Open external documents

jFX.ShowExternalDocument method allows you to open external documents with the default installed app.

It expects a single parameter which is the document or resource Uri (link).

You can use File.GetUri to get the Uri of a local file.

For example to open a local PDF document:

fx.ShowExternalDocument(File.GetUri("C:\Users\H\Documents", "Document.pdf"))

You can also use it with a non-local resource:

fx.ShowExternalDocument("http://www.b4x.com")

Caveats:
- This method doesn't throw any error if the resource cannot be opened.
- You cannot use this method with assets files (files added to the Files tab). It will only fail in Release mode when the files are packaged inside the jar.
You can use File.Copy to copy it from the assets folder and then open it.

This method was added in V1.00 beta 6.

It does work here (I've tested it with the http url on a Mac). If it doesn't work then your other option is to find the correct app and start it with jShell.

What do you mean with feedback?
If you want to open url you give already....

fx.ShowExternalDocument("http://www.b4x.com")

in this case you are opening the url http://www.b4x.com

Just remember the url used. Or what do you mean?

no, you dont get any callback as the command is calling a windows method which, in case of a url, usually just open the browser to show the url.
