我正在通过AWS java SDK将图像文件上传到S3，但我在上传时收到以下错误，我已经检查了我的凭据和我的存储桶它们没问题
Unable to calculate MD5 hash: /data/user/0/competent.groove.feetport/files/data/user/0/competent.groove.feetport/app_imageDir/IMG_20161122_073058.jpg: open failed: ENOENT (No such file or directory)
我从相机捕捉图像并将图像保存在手机中，这是我的代码

答案 0 :(得分：0)
这与S3无关。
ENOENT (No such file or directory)是本地错误：找不到文件。
仔细查看错误消息中的路径。我在这里包含了路径，并添加了一些换行符以便于阅读。我没有编辑这个，重要的是，我没有多次粘贴它：
/data/user/0
/competent.groove.feetport
/files/data/user/0
/competent.groove.feetport
/app_imageDir/IMG_20161122_073058.jpg
我并不是说 错误，但肯定看起来错了。当然看起来你正试图从你错误构造的路径上传文件，在目录结构中有一些重复......并且没有这样的目录，没有这样的文件。
