In imagepicker.android.ts we have:

            // DownloadsProvider
            else if (UriHelper.isDownloadsDocument(uri)) {
                id = DocumentsContract.getDocumentId(uri);
                // Since Oreo the downloads id may be a raw string,
                // containing the file path:
                if (id.indexOf("raw:") !== -1) {
                    return id.substring(4, id.length);
                }
                contentUri = android.content.ContentUris.withAppendedId(
                    android.net.Uri.parse("content://downloads/public_downloads"), long(id));

                return UriHelper.getDataColumn(contentUri, null, null);
            }

that we can maybe replace with:

            else if (UriHelper.isDownloadsDocument(uri)) {
                return UriHelper.getDataColumn(uri, null, null);
            }

But a bigger problem awaits:

    private static getDataColumn(uri: android.net.Uri, selection, selectionArgs) {
        let cursor = null;
        let columns = [android.provider.MediaStore.MediaColumns.DATA];
        let filePath;

        try {
            cursor = this.getContentResolver().query(uri, columns, selection, selectionArgs, null);
            if (cursor != null && cursor.moveToFirst()) {
                let column_index = cursor.getColumnIndexOrThrow(columns[0]);
                filePath = cursor.getString(column_index);
     ......
     ......

On Android 7, the columns for the rows of cursor are:
_id, _data, _size, _display_name, mime_type, title, date_added, date_modified.............

On Android 8.1 (I have a Go edition) the _data and a lot of the other columns are not there anymore.

So in the query it is looking for _data, but it does not exist.

I guess the only way to fix this is to copy the contents to a stream and save it in a cache directory or something.

I added this debug code to determine the columns returned:

for(var i=0; i<cursor.getColumnCount();i++)
{
    console.log(`Column Name: ${cursor.getColumnName(i)}`);
}

I'm also having this issue. What workaround would you suggest for now?

[leoncc]

I did a ugly one. I replaced ..../node_modules/nativescript-imagepicker/imagespicker.android.js with the file in the zip below. As you know with the next tns plugin add... it will be gone.

imagepicker.android.js.zip

Thanks @leoncc! I replaced the contents of the file, but I'm still getting the error. Is there some other npm command I need to run to register the changes? If not, I'll just hold out for the next release.

[leoncc]

Try deleting the platforms folder (the one of your project not in node_modules) and then do tns run android again.

I also run into the same issue as described. The temporary fix posted in the file by @stevenspiel is working for me but it would by nice to have a more permanent solution in the repo.

I'm having the same problem the plugin will be updated with this solution above?

[Jarrich]

Same issue here!
