使用Facebook Android SDK 3.0上传照片时出现间歇性SSL错误

我正在使用Facebook Android SDK 3.0将照片上传到我的相册.一切正常,但有时第一次上传失败,出现了一些意想不到的SSL错误.

try {
        connection = createConnection(url);

        serializetoUrlConnection(requests, connection);
    } catch (IOException e) {
        // THIS IS WHERE THE ERROR ORIGINATES FROM!
        throw new FacebookException("Could not construct request body", e);
    } catch (JSONException e) {
        throw new FacebookException("Could not construct request body", e);
    }

在Eclipse中悬停e会显示以下信息：

javax.net.ssl.SSLException：写入错误：ssl = 0x4f033008：系统调用期间的I / O错误,管道损坏
javax.net.ssl.SSLException：写入错误：ssl = 0x4f033008：系统调用期间的I / O错误,管道损坏

这是SDK中的错误吗？有没有人遇到过这个？更重要的是,我该如何解决？

解决方法:

我几乎准备好接受我之前(删除)的答案,直到我看到这篇文章：http://vikaskanani.wordpress.com/2011/01/11/android-upload-image-or-file-using-http-post-multi-part/

我决定试一试,它似乎工作！这是我的代码：

for (Bitmap b : bitmaps) {
    // id is just a string
    String response = executeUpload(b, id);

    // do something with the response
}

private String executeUpload(Bitmap b, String id) throws MalformedURLException, IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    b.compress(CompressFormat.PNG, 100, baos);
    byte[] data = baos.toByteArray();

    HttpPost postRequest = new HttpPost("https://graph.facebook.com/me/photos");
    HttpParams params = new BasicHttpParams();
    httpconnectionParams.setConnectionTimeout(params, 3000);
    HttpClient httpClient = new DefaultHttpClient();
    httpClient.setHttpRequestRetryHandler(new DefaultHttpRequestRetryHandler(2, true));

    ByteArrayBody bab = new ByteArrayBody(data, id + ".png");
    multipartentity reqEntity = new multipartentity(HttpMultipartMode.broWSER_COMPATIBLE);
    reqEntity.addPart("access_token", new StringBody(activeFacebookAccesstoken));
    reqEntity.addPart("message", new StringBody(""));
    reqEntity.addPart("picture", bab);
    postRequest.setEntity(reqEntity);
    HttpResponse response = httpClient.execute(postRequest);
    BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
    String s;
    StringBuilder builder = new StringBuilder();
    while ((s = reader.readLine()) != null) {
        builder = builder.append(s);
    }

    return builder.toString();
}

如上面的链接所述,您必须安装最新的HttpClient(位于http://hc.apache.org/downloads.cgi).

另一个需要注意的重要事项是,Facebook支持任一维度的最大图像大小为720像素.在我的代码中,我在进行上传之前将位图缩放到该大小限制内,这极大地提高了性能.
