无法使用API​​

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，说它无法找到该文件，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，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的旧版本中修复的，人们已经确认它是，但那是不久前我正在使用最新版本{{1} }。

我用来上传的代码如下：

1.13.0

有谁知道这里出了什么问题以及我怎么能让这个工作？
