通过SMB协议进行文件传输android错误

我想将文件从我的应用程序传输到无线samba设备。我编写了以下代码，但不起作用。设备的ip=192.168.1.2:8181，用户名=Admin，密码=[empty]。当我尝试从pc浏览器访问该设备时，该设备会显示完整的文件

您应该安装一个日志收集器应用程序，以查明是否生成了任何错误

可能会有帮助

之后，您可以在错误日志中找到可能的原因。 如果无法写入该文件，则至少应引发IOException

---

此外，仔细检查您是否没有共享文件夹名称（即，您确实希望写入SMB设备上未命名的根文件夹）也会很有帮助，如果是这样，请从SMB url中删除端口后的两个斜杠之一（共享名称应放在这两个斜杠之间）可能会有帮助。

您面对的确切症状是什么而不是“不工作”？在我检查设备时，设备上的文件内容未更新以前有人有过相同的问题吗
