Reading External Storage does not work

[wamphlett]

Reading external storage devices is not supported by this package.

Reproduce

Run the example app on a physical device and select an external device as the source. e.g. an SD card.

Error

Error: RangeError (length): Invalid value: Only valid value is 0: 1

Cause

The cause of the issue is a bad assumption that all directory paths include primary%3A. Specifically this line

saf/lib/src/storage_access_framework/api.dart

Line 32 in dc3268f

String directoryPathUriString = uriString.split("primary%3A")[1];

External devices do not contain primary, instead they appear to contain a devide id so this is causing an invalid index. For example

"uri" -> "content://com.android.externalstorage.documents/tree/ABB8-7BD7%3APRIVATE%2FSONY"

I have the same issue. In my case the uri is content://com.android.externalstorage.documents/tree/00D0-08B0%3A

@wamphlett and @Qubitza Where you able to resolve this ?

[wamphlett]

I spent a bit of time trying to see if I could make a PR but it was a bit more work than I had time for at the time. As I got no reply on this thread, I just started using a different package: https://pub.dev/packages/saf_stream. Works great.

Thanks alot i will check this out,

Quick question, were you able to access usb device using this package or just sd card ?

[wamphlett]

I have not tried a USB device but I would imagine it would have the same path format so should work the same.

I also ended up using saf_util and saf_stream. In my case I also needed to access external storage and it worked flawlessly.

Thanks a lot @Qubitza and @wamphlett .

I was used it to read a usb drive and it worked great.
