5 years ago withNavigateUpTo() can tell chooser kernel whether could go up from a folder:
.withNavigateUpTo(new ChooserDialog.CanNavigateUp() {
@Override
public boolean canUpTo(File dir) {
return true;
}
})but you couldn't navigate up to a folder unless it has read permission.
default withNavigateUpTo() handler checks the permission of dir to protected user cannot navigate to security area. and kernel codes do similar works on listing directories and files.
for the same reason, you could only give a start path if it has read permission.
.withStartFile(_path) will check the start path for its existence and permission and relocated to internal storage root (/sdcard) if necessary. generally you couldn't use .withStartFile("/") because kernel code disable it (see ChooserDialog.java#L771).
unfortunately we had had no effective approaches to switch in multiple roots such as internal and external storage root.
in you case, try your callback with
too bad that almost not work.withNavigateUpTo(), it could be a way.

I used the template in your README.md to create a basic chooser for selecting a file, setting the path to the devices public Downloads folder. This works, and looks great. The only problem I'm running into is that the user can't navigate up past the root of internal storage. If I tell it to set the path as ROOT (Environment.getRootDirectory().toString()) than they can navigate everywhere, but the average user may be confused by the file path they are looking at. Can you suggest a way of allowing them to navigate to a file that may be on local OR external storage? I have already implemented the appropriate read permissions.
