我想使用驱动器api将大文件(> 10Mb)上传到Google云端硬盘。它适用于较小的文件(当有良好的wifi时),使用直接上传:

Drive.Files.Insert insert = driveService.files().insert(fileMetadata, mediaContent);
MediaHttpUploader uploader = insert.getMediaHttpUploader();
uploader.setChunkSize(UPLOAD_CHUNK_SIZE);
uploader.setDirectUploadEnabled(true);
insert.execute();

现在,假设我们正在上传更大的文件。我们希望跟踪连接,因此我们使用MediaHttpUploader方法提供的可恢复上传...

uploader.setDirectUploadEnabled(false);
uploader.setProgressListener(new MediaHttpUploaderProgressListener() {
    @Override
    public void progressChanged(MediaHttpUploader mediaHttpUploader) throws IOException {
        switch (mediaHttpUploader.getUploadState()) {
            case INITIATION_STARTED:     break;
            case INITIATION_COMPLETE:  break;
            case MEDIA_IN_PROGRESS:   break;
            case MEDIA_COMPLETE:        break;
        }
    }
});

确定。但是没有 MEDIA_FAILED 的状态,我是否正确?如果上传未达到 MEDIA_COMPLETE ,我该怎么办?

另外,我找不到恢复上传的方法。所以,即使100Mb的上传量达到90%并且失败了,我所能做的就是重新开始它?
