为什么startForeground的通知错误：java.lang.RuntimeException：在Android 8或更高版本的服务器上将图像上传到服务器时

Question

我想使用截击将图像上传到服务器。图片正确上载，但在安卓8版或更高版本中出现错误。 错误是 错误的startForeground通知：java.lang.RuntimeException：服务通知的无效通道：

    public void uploadMultipart() {
    if(filePath!=null) {
    try {
    String path = getPath(filePath);
    String uploadId = UUID.randomUUID().toString();
    Log.e("DATA",path+"\n\n"+uploadId);
    new MultipartUploadRequest(getContext(), uploadId, Const.UPLOAD_DOC_URL)// HERE ADD PHP URL NAME
    .addFileToUpload(path, "image") //Adding file
    .setNotificationConfig(new UploadNotificationConfig())
    .setMaxRetries(2)
    .startUpload(); //Starting the upload
    } catch (Exception exc) {
        Toast.makeText(getContext(), "Category Added successfully 111", Toast.LENGTH_SHORT).show();
    }
    }
    else
        Toast.makeText(getContext(), "Please select image", Toast.LENGTH_SHORT).show();
