AWS S3上传卡在等待状态

Question

我已经查看了有关此问题的几个问题和答案，但是仍然无法上传到S3存储桶。我已经在应用程序标记中的清单中声明了该服务。每个日志语句都返回正确的信息，但是状态始终为WAITING，并且不会触发任何传输侦听器。我没有收到任何错误，并且S3存储桶仍然为空。我究竟做错了什么？public void uploadStoredItems() {    TransferUtility transferUtility = TransferUtility.builder()            .context(AWSProvider.getInstance().getContext())            .awsConfiguration(AWSProvider.getInstance().getConfiguration())            .s3Client(new AmazonS3Client(AWSProvider.getInstance().getIdentityManager().getCredentialsProvider()))            .build();    try {        for (File csvFile : csvFiles) {            String filename = csvFile.getName(); //.substring(csvFile.getName().lastIndexOf('/') + 1);            Log.d(TAG, "This is the filename for upload: " + filename);            // FileReader reads text files in the default encoding.            String line = null;            FileReader fileReader = new FileReader(csvFile);            // Always wrap FileReader in BufferedReader.            BufferedReader bufferedReader = new BufferedReader(fileReader);            while ((line = bufferedReader.readLine()) != null) {                Log.d(TAG, "Here are the lines: " + line);            }            // Always close files.            bufferedReader.close();            TransferObserver uploadObserver = transferUtility.upload(filename, csvFile);            // Gets id of the transfer.            Log.d(TAG, "This is the bucket: " + uploadObserver.getBucket());            Log.d(TAG, "This is the state: " + uploadObserver.getState());            Log.d(TAG, "This is the id: " + uploadObserver.getId());

事实证明，我必须声明TransferUtility服务以与我调用它的服务正在运行的过程相同的方式运行：

<application

    ...

    <service

      android:name=".MainService"

      android:enabled="true"

      android:process=":main_service"

      android:stopWithTask="false" />

    <service

      android:name="com.amazonaws.mobileconnectors.s3.transferutility.TransferService"

      android:process=":main_service"

      android:enabled="true" />

    ...

</application>
