【问题描述】：
我正在尝试使用 TransferManager.upload(String bucket, String key, File file) 从 Android 应用程序将一个中等大小的文件（大约 10 MB）上传到我的 AWS S3 存储桶。
以下代码间歇性工作：
CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(...);
mTransfer = new TransferManager(credentialsProvider);
mTransfer.upload("bucket", key, file);
大约一半的时间，这很有效。另一半时间，由于SSLException，上传失败。是否预计上传到 S3 会如此不可靠？我应该在客户端代码中处理重试吗？
