Cannot set the initial location of documents navigator using Storage Access Framework (SAF)

Question

The documentation says \"Callers can set a document URI through EXTRA_INITIAL_URI to indicate the initial location of documents navigator.\"

But it won

Answer 1

From DocumentsContract.EXTRA_INITIAL_URI:

Location should specify a document URI or a tree URI with document ID. If this URI identifies a non-directory, document navigator will attempt to use the parent of the document as the initial location.

As far as I'm aware

• You cannot specify a starting location using an arbitrary URI, e.g. Uri.fromFile, it needs to originate from a DocumentsProvider
• You cannot specify a starting location on API 25 and below

Assuming uri was retrieved from Intent.ACTION_OPEN_DOCUMENT_TREE:

DocumentFile file = DocumentFile.fromTreeUri(context, uri);
intent.putExtra(EXTRA_INITIAL_URI, file.getUri());
