You need to use a full url e.g.
file:///storage/emulated/0/Download/images/myfile.html

The Filelist method returbs a list of files
You can't assign a list to the HomeUrl... try the first item from the list

1. You cannot set the WebViewer.HomeUrl to a list.
2. You cannot access a non-media file on Android 11+.

You need SAF for it. But you cannot access /Download and the root dir of the external stoarge with SAF.

[Taifun]

There you go
As you can see, you get a list, which has one item
So what about using the select list item block to get the first item from that list?

my version android is 9 not 11 or + . so it would be work no?

[CanalDTodoUnPoco_PC]

yes i read both post but i will try that but i am little confuse about the route that you show me. where i need to put this route? . inside a file list? or where exactly? i am making the modify using select item. like this its correct?

@CanalDTodoUnPoco_PC

my version android is 9

You need READ permission on Android < 11.

[CanalDTodoUnPoco_PC]

yes i ask the permission in the initialize screen like you can see in my blocks code

As I said:

@Anke

You cannot set the WebViewer.HomeUrl to a list.
