Amazon S3 分段上传期间的 javax.net.ssl.SSLException

Question

我正在使用 Simpl3r a simple high level Android API for robust and resumable multipart file uploads using the Amazon S3 service 将媒体文件上传到我的存储桶。

在某些上传时，我收到 SSLException 错误。以下是引发异常的代码：

（根据 Simpl3r 示例，我的类是 IntentService 的子类）

@Override
protected void onHandleIntent(Intent intent) {

    String filePath = intent.getStringExtra(ARG_FILE_PATH);
    final String s3ObjectKey = intent.getStringExtra(ARG_OBJECT_KEY);
    File fileToUpload = new File(filePath);
    String s3BucketName = getString(R.string.s3_bucket);

    final String msg = "Uploading " + s3ObjectKey + "...";

    // create a new uploader for this file
    uploader = new Uploader(this, s3Client, s3BucketName, s3ObjectKey, fileToUpload);

    // listen for progress updates and broadcast/notify them appropriately
    uploader.setProgressListener(new UploadProgressListener() {
        @Override
        public void progressChanged(ProgressEvent progressEvent,
                                    long bytesUploaded, int percentUploaded) {

            Notification notification = buildNotification(msg, percentUploaded);
            nm.notify(NOTIFY_ID_UPLOAD, notification);
            broadcastState(s3ObjectKey, percentUploaded, msg);
        }
    });

    // broadcast/notify that our upload is starting
    Notification notification = buildNotification(msg, 0);
    nm.notify(NOTIFY_ID_UPLOAD, notification);
    broadcastState(s3ObjectKey, 0, msg);

    try {
        String s3Location = uploader.start(); // initiate the upload
        broadcastStateDone(s3ObjectKey, s3Location, "File successfully uploaded to " + s3Location);
    } catch (UploadIterruptedException uie) {
        broadcastStateError(s3ObjectKey, "User interrupted");
    } catch (Exception e) {
        e.printStackTrace();
        broadcastStateError(s3ObjectKey, "Error: " + e.getMessage());
    }
}

这是堆栈跟踪：

我的 Exception 子句没有捕获到异常。这意味着应用卡在永无止境的“上传”状态。

有什么想法吗？

这些上传需要多长时间？可以重置吗？
