打开失败:ENOENT(没有此类文件或目录)错误

Question

我试图通过使用亚马逊S3安卓库来上传使用相机拍照的照片时遇到问题.

保存图片

File _photoFile = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM),   (cal.getTimeInMillis() + ".jpg"));

            try {
                if (_photoFile.exists() == false) {
                    _photoFile.getParentFile().mkdirs();
                    _photoFile.createNewFile();
                }

            } catch (IOException e) {
                // Log.e(TAG, "Could not create file.", e);
            }
            // Log.i(TAG, path);

            filePath = Uri.fromFile(_photoFile);
            Intent cameraIntent = new Intent(
                    android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, filePath);
            startActivityForResult(cameraIntent, 1);

要使用filePath上传图片:

try {
            s3Client.createBucket(Constants.getPictureBucket());

            // Content type is determined by file extension.
            PutObjectRequest por = new PutObjectRequest(
                    Constants.getPictureBucket(), Constants.PICTURE_NAME,
                    new java.io.File(filePath));
            s3Client.putObject(por);
        } catch (Exception exception) {

            result.setErrorMessage(exception.getMessage());
        }

我一直在收到错误 Unable to calclualte MD5 hash:/file:/storage/sdcard0/DCIM/13161272646580.jpg open failed:ENOENT (No such file or directory)

但是当我浏览我的SD卡的目录时,我可以在那里找到图片(图片已经创建),并且我已经创建了相关的权限.

我真的不记得我做了什么。但这是我使用的有效代码。希望可以帮助到大家！

AmazonS3Client s3Client = new AmazonS3Client(new BasicAWSCredentials("XXX", "XXX"));
String time = "" + System.currentTimeMillis();
PutObjectRequest por = new PutObjectRequest("fraternity", xyz_url_xyz + "/avatar" + time + ".jpg", new java.io.File(params[0]));
por.setCannedAcl(CannedAccessControlList.PublicRead);
s3Client.putObject(por);
ResponseHeaderOverrides override = new ResponseHeaderOverrides();
override.setContentType("image/jpeg");
GeneratePresignedUrlRequest urlRequest = new GeneratePresignedUrlRequest("xyz_url_xyz/avatar.jpg");
urlRequest.setExpiration(new Date(System.currentTimeMillis() + 3600000));  
urlRequest.setResponseHeaders( override );
s3Client.generatePresignedUrl(urlRequest);
