Question

我正在尝试从Android设备读取文件并将其上传到服务器，我的代码如下：

MultipartUtility multipart = new MultipartUtility(ForSaleConstants.REVIEW_IMAGE_UPLOADER, NetworkManager.CHARACTER_SET);
multipart.addFormField(ForSaleConstants.PHONE, phone);

String uriString = extraFileUri.toString();
Log.e("File_URI", uriString);
uriString = Uri.decode(uriString);
Log.e("File_URI2", uriString);

if (uriString.contains("file://")) {
   uriString = uriString.replace("file://", "");
   File uploadFile = new File(uriString);
   multipart.addFilePart(("image"), uploadFile);
} else if (uriString.contains("content://")) {
   uriString = FileManager.getInstance().getRealPathFromImageUri(context, Uri.parse(uriString));
   File uploadFile = new File(uriString);
   multipart.addFilePart(("image"), uploadFile);
} else {
   try {
      File uploadFile = new File(uriString);
      multipart.addFilePart(("image"), uploadFile);
   } catch (Exception e) {
      e.printStackTrace();
   }
}

我遇到了以下崩溃：
