Android 当文件大小大于可恢复上载区块大小时，文档列表API文件上载失败

我正在尝试使用文档列表API让Android应用程序与Google Docs/Drive交互：

我在使用GData可恢复上载协议上载文件时遇到了一些问题，即：

我使用的是512KB的块大小。小于区块大小的文件上载成功，但大于区块大小的文件将在第一个区块完成之前失败。即使我将块大小增加到1MiB或2MiB，这也是正确的。768KiB文件将在块大小为512KiB时失败，但在块大小为1MiB时成功

大于数据块大小的文件确实通过了第一步，即将XML发布到“可恢复创建媒体”链接。然后，我看到用于发送区块的HttpContent实现的writeTo（）方法中抛出了一个SSLException。此异常发生在第一个块的中间，例如：

javax.net.ssl.SSLException: Write error: ssl=0x2a6318: I/O error during system call, Broken pipe
    at org.apache.harmony.xnet.provider.jsse.NativeCrypto.SSL_write(Native Method)
    at org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl$SSLOutputStream.write(OpenSSLSocketImpl.java:713)
    at libcore.net.http.FixedLengthOutputStream.write(FixedLengthOutputStream.java:41)
    at com.google.api.client.http.AbstractInputStreamContent.writeTo(AbstractInputStreamContent.java:89)

请注意，要查看上述内容，我必须在writeTo（）方法中捕获IOExceptions（在记录它们之后重新调用它们）。否则，由于内容被突然切断，我只会看到一个通用的“400错误请求”响应

我试过几种不同的测试设备，例如Galaxy Nexus（VZW/CDMA，4.0.2，股票），Droid4（Moto 2.3.6，股票）DroidX（股票）

上载第一个区块的请求上的标题：

Accept-Encoding: gzip
Authorization: GoogleLogin auth=XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Content-Length: 524288
Content-Range: 0-524287/1635085
Content-Type: image/png
GData-Version: 3.0
User-Agent: XXXXXXXXXXXXXX

谢谢你的建议

更新：添加代码段，这是放置下一个块的位

private boolean putNext() 
throws CancelException, DirectoryException {
    try {
        ByteArrayContent content = new ByteArrayContent(mediaType, buffer, 0, bufferLength);

        HttpRequest request = conn.getHttpRequestFactory().buildPutRequest(new GenericUrl(nextLocation), content);

        HttpHeaders requestHeaders = request.getHeaders();
        requestHeaders.setContentLength(String.valueOf(bufferLength));
        requestHeaders.setContentType(mediaType);

        if (sent != 0 || bufferLength != size) {
            // Only set content range when file will span multiple chunks.
            requestHeaders.setContentRange(sent + "-" + (sent + bufferLength - 1) + "/" + size);
        }

        HttpResponse response = request.execute();

        sent += bufferLength;
        bufferLength = 0;

        HttpHeaders responseHeaders = response.getHeaders();

        int statusCode = response.getStatusCode();
        if (statusCode == GoogleDriveConnection.RESPONSE_308_RESUME_INCOMPLETE) {
            nextLocation = responseHeaders.getLocation();
            return false;
        } else if (statusCode >= 200 && statusCode < 400) {
            Document responseDom = DomUtil.load(response.getContent());
            return true;
        } else {
            Log.w(LOG_TAG, "Google Drive upload error: Invalid response code to upload request: " + statusCode);
            throw DirectoryException.networkErrorHost(null, catalog.getHostName());
        }
    } catch (IOException ex) {
        Log.w(LOG_TAG, "Google Drive write error.", ex);
        throw DirectoryException.networkErrorHost(ex, catalog.getHostName());
    } catch (SAXException ex) {
        throw DirectoryException.networkErrorHost(ex, catalog.getHostName());
    }
}

private boolean putNext（）
抛出CancelException，DirectoryException{
试一试{
ByteArrayContent内容=新的ByteArrayContent（mediaType，buffer，0，bufferLength）；
HttpRequest请求=conn.getHttpRequestFactory（）.buildPutRequest（新的GenericUrl（nextLocation），content）；
HttpHeaders requestHeaders=request.getHeaders（）；
requestHeaders.setContentLength（String.valueOf（bufferLength））；
requestHeaders.setContentType（mediaType）；
如果（已发送！=0 | |缓冲长度！=大小）{
//仅当文件将跨越多个块时设置内容范围。
setContentRange（发送+“-”+（发送+缓冲长度-1）+“/”+大小）；
}
HttpResponse response=request.execute（）；
发送+=缓冲区长度；
缓冲长度=0；
HttpHeaders-responseHeaders=response.getHeaders（）；
int statusCode=response.getStatusCode（）；
如果（statusCode==GoogleDriveConnection.RESPONSE\u 308\u RESUME\u Complete）{
nextLocation=responseHeaders.getLocation（）；
返回false；
}否则如果（状态代码>=200&&statusCode<400）{
documentresponsedom=DomUtil.load（response.getContent（））；
返回true；
}否则{
Log.w（Log_标签，“谷歌硬盘上传错误：上传请求的响应代码无效：“+statusCode”）；
抛出DirectoryException.networkErrorHost（null，catalog.getHostName（））；
}
}捕获（IOEX异常）{
Log.w（Log_标签，“谷歌硬盘写入错误”，ex）；
抛出DirectoryException.networkErrorHost（例如catalog.getHostName（））；
}捕获（SAXEx异常）{
抛出DirectoryException.networkErrorHost（例如catalog.getHostName（））；
}
}

另一个可能很重要的注意事项是：SSLException失败是由Content Range标头的存在触发的。如果我省略它，第一个大于块大小的文件块将毫无例外地成功上载。服务器返回一个201创建的文件，该文件被创建为一个被截断的512KB大小

再次感谢

更新2

我现在有了一个纯Java应用程序来演示这个问题。这是一个包含库的Eclipse项目，但在其他地方使用起来应该很简单。

需要一个身份验证令牌来测试它。它需要三个命令行参数才能运行：

[文件名][内容/类型][AuthToken]

（我目前正在从real app的调试输出中剪切/粘贴AuthToken）

以下是此应用程序的修剪输出：
