尝试使用Android中的MultipartEntity上传图像后，我收到以下错误消息：
Error: Problem with [picture] (File upload error 4)
我使用以下代码上传图片：
String url = "http://www.uploadurl.com/api/files.php";
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(url);
MultipartEntity multiEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Temp/" + IMAGE_FILENAME);
ContentBody cBody = new FileBody(file);
StringBody sb1 = new StringBody(getNameFormatted());
StringBody sb2 = new StringBody(getDeviceID());
MultipartEntity multipartContent = new MultipartEntity();
multipartContent.addPart("name", sb1);
multipartContent.addPart("uuid", sb2);
multipartContent.addPart("picture", cBody);
httpPost.setEntity(multipartContent);
HttpResponse response = httpClient.execute(httpPost, localContext);
我不确定我做错了什么，我过去只使用JSON数组作为实体的一部分使用与此非常类似的代码上传图像，而不是单独添加所有这些。我认为它与图像设置到ContentBody的方式有关吗？我真的不确定。
