这是我的上传任务:

请提供帮助。

使用以下命令进行DIR:


“/your\u folder\u name/”

您需要
DropboxAPI
createFolder
方法。请参阅。

创建文件夹时,您可以简单地给出这样的答案!这很简单

 dropbox.putFile("Mynumber2/myregion2/"+"/"+"A"+"/"+"B"+"/"+"ENTRY.db", fileInputStream,file.length(), null, null);

如果您这样做,mynumber2-->myregion2-->A-->B将是您在dropbox上创建的文件夹结构

根据dropbox文档

try {
      // creating folder
      val fo = client.files().createFolderV2(File.separator + folderPath)
     } catch (ex: CreateFolderErrorException) {
            if (ex.errorValue.isPath && ex.errorValue.pathValue.isConflict) {
                // folder already exist
             }
      }
