Storage Access Framework删除目录返回无效的URI

Question

我尝试使用Storage Access Framework创建和删除目录

public void create() {
    Intent intent = new Intent(Intent.ACTION_CREATE_DOCUMENT);
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    intent.setType(DocumentsContract.Document.MIME_TYPE_DIR);
    intent.putExtra(Intent.EXTRA_TITLE, "folder");
    this.startActivityForResult(intent, 25);
}

public void delete() {
    Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
    this.startActivityForResult(intent, 27);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent resultData ) {
    if (resultCode == Activity.RESULT_OK) {
        if (resultData != null) {
            Uri uri = resultData.getData();
            if (requestCode == 25) {
                final int takeFlags = resultData.getFlags() & (Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
                this.getContentResolver().takePersistableUriPermission(uri, takeFlags);
            } else if (requestCode == 27) {
                deleteFile(uri);
            }
        }
    }
}

private void deleteFile(Uri uri) {
    try {
        DocumentsContract.deleteDocument(this.getContentResolver(), uri);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

我正确创建了目录，但是无法将其删除，出现错误“无效的URI ...”

谢谢
