I am writing a function that essentially gets data from an http request as a byte array, then writes it to a file in the temporary directory in order to share to wherever the user desires. I have successfully gotten this to work on iOS, but for some reason every time I reach the share code on Android I get the following error:

PlatformException(error, Failed to find configured root that contains /storage/emulated/0/Android/data/<bundle-identifier-hidden-here-for-privacy>/cache/share/testfile.pdf, null, java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/0/Android/data/<bundle-identifier-hidden-here-for-privacy>/cache/share/testfile.pdf

When I print file.path on the file I saved right before I attempt to share, I get this:

/data/user/0/<bundle-identifier-hidden-here-for-privacy>/cache/testfile.pdf

Here is the code itself, it's fairly straightforward. I'm using share_plus(^6.0.1), path_provider(^2.0.11), and http(^0.13.5) (which seems to be irrelevant here beyond being the source of the data):

var res = await http.post(
    Uri.parse(url),
    body: {"document_html": htmlString},
);

var temp = await getTemporaryDirectory();

File file = File("${temp.path}/testfile.pdf");

file = await file.writeAsBytes(res.bodyBytes);

String path = file.absolute.path;
Share.shareFiles([path]).catchError((err) {
    print(err);
});

I haven't tested your implementation but recently I needed to implement share plus but using XFile, see:

import 'package:path_provider/path_provider.dart';
import 'package:image_picker/image_picker.dart';
import 'package:screenshot/screenshot.dart';
import 'package:share_plus/share_plus.dart';


IconButton(
      onPressed: () async {
        await widget.screenshotController
            .capture(pixelRatio: 1.5)
            .then((bytes) async {
          final Directory output = await getTemporaryDirectory();
          final String screenshotFilePath = '${output.path}/appName.png';
          final File screenshotFile = File(screenshotFilePath);
          await screenshotFile.writeAsBytes(bytes!);
          Share.shareXFiles(
            [XFile(screenshotFilePath)],
            text:
                "Text. My invite link:\n$appLink",
            sharePositionOrigin: () {
              RenderBox? box = context.findRenderObject() as RenderBox?;
              return box!.localToGlobal(Offset.zero) & box.size;
            }(),
          );
        }).catchError((onError) {
          print(onError);
        });
      },
      icon: const Icon(Icons.share_outlined),
    );

  • Wow, thanks for that quick response. You exposed a pretty major oversight on my end. I'm working with a codebase from a previous developer and it looks like they had used the now-discontinued share package, so when I wrote my method it used that instead of share_plus. Corrected the import and used your XFile example, and immediately got it working. Thanks again! – holycamolie Oct 25 '22 at 18:41
