无法从Android将视频文件上传到AWS S3存储桶

Question

我正在尝试将文件/图像/视频从android上传到AWS s3存储桶。一些视频已成功上传，但有时当我上传视频时却未上传并引发以下错误：

     com.amazonaws.AmazonClientException: Unable to verify integrity of data upload.  Client 
     calculated content hash didn't match hash calculated by Amazon S3.  You may need to delete 
     the data stored in Amazon S3.

这是我的代码

 private fun getS3Client(
        accessKey: String,
        secretKey: String,
        sessionToken: String
    ): AmazonS3Client? {

        var sS3Client: AmazonS3Client? = null
            try {
                val region: Region = Region.getRegion("us-west-2")
                val credentials =
                    BasicSessionCredentials(accessKey, secretKey, sessionToken)
                val clientConfiguration = ClientConfiguration()
                    .withMaxErrorRetry(3) // 3 retries
                    .withConnectionTimeout(120000) // 120,000 ms
                    .withSocketTimeout(120000) // 120,000 ms

                sS3Client = AmazonS3Client(credentials, region, clientConfiguration)
            } catch (e: JSONException) {
                e.printStackTrace()
            }
        return sS3Client
    }

            val observer: TransferObserver =
                transferUtility.upload(bucket_name, file.name, file,objectMetadata)

提前谢谢！
