无法使用API 将图像上传到Twitter

Question

我正在尝试使用他们的API将图像上传到Twitter，但它始终无法抛出错误，说它无法找到文件，即使它肯定存在，因为我使用相同的路径将其上传到其他网络并且它在我的预览框中正确显示。

com.twitter.sdk.android.core.TwitterApiException: /-1/1/content:/media/external/images/media/100883/ORIGINAL/NONE/1159437588: open failed: ENOENT (No such file or directory)

一些谷歌搜索显示这个错误本来是在Android的Twitter SDK的旧版本中修复，并且人们已经确认它是，但那是一段时间之前，我使用的是最新版本1.13.0。

我用来上传的代码如下：

//img = Uri passed from calling method
File photo = new File(img.getPath());
TypedFile typedFile = new TypedFile("application/octet-stream", photo);
TwitterApiClient twitterApiClient = TwitterCore.getInstance().getApiClient(twitSession);
MediaService  mediaService = twitterApiClient.getMediaService();
final StatusesService statusesService = twitterApiClient.getStatusesService();

mediaService.upload(typedFile, null, null, new Callback<Media>() {
    @Override
    public void success(final Result<Media> result) {
        statusesService.update(input, null, null, null, null,
        null, null, null, result.data.mediaIdString, new Callback<Tweet>() {
                    @Override
                    public void success(Result<Tweet> result) {
                        Log.d("Twitter image callback", "Successfully posted image and text to Twitter!");
                    }

                    @Override
                    public void failure(TwitterException e) {
                        if (result != null) {
                            Log.e("Twitter image callback", "Result is - " + result.toString());
                        }
                        Log.d("Twitter image callback", "Failed to post image and text to Twitter!");
                    }
                });
    }

    @Override
    public void failure(TwitterException e) {
        Log.d("Twitter image callback", "Failed to upload image to Twitter!");
        e.printStackTrace();
    }
});

有谁知道这里出了什么问题，我怎么能让这个工作？
