我正试图将图像文件上传到服务器，当我在Emulator上尝试时，这一切都很正常，但从设备上传时，会出现内部服务器错误。
我正在执行的步骤是：
1] 从相机中捕获图像并将其存储在外部存储器中
2] 在imageview上显示文件
3] 单击按钮，将文件从外部存储上传到服务器
当点击上传按钮时，我已经写了代码。
Category=(String) category.getSelectedItem();
Bitmap sendbitmap = rotateBitmapImage(BitmapFactory.decodeFile(mCurrentPhotoPath));
ByteArrayOutputStream stream = new ByteArrayOutputStream();
sendbitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
//compress to which format you want.
byte [] byte_arr = stream.toByteArray();
String image_str = Base64.encodeBytes(byte_arr);
final ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("image",image_str));
nameValuePairs.add(new BasicNameValuePair("userid",Integer.toString(userid)));
nameValuePairs.add(new BasicNameValuePair("State",State));
nameValuePairs.add(new BasicNameValuePair("rc",rc));

为什么会发生这种情况？在模拟器上它工作得很好，但在设备上它给出了问题。它卡在进度条上，2-3分钟后显示Toast消息为内部服务器错误
实际上问题是使用base64编码来传输高质量图像。我正试图上传来自相机的原始图像。我用MultipartEntity替换了base64编码传输。
