通过 SMB 协议传输文件 android 错误

Question

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无法正常工作。设备具有 ip=192.168.1.2:8181 且用户名=Admin 和密码=[空]。而设备显示完整当我尝试从我的电脑浏览器访问它时的文件。

Answer 1

您应该安装一个日志收集器应用程序来查看您是否产生了任何错误。

This 可能会有所帮助。

之后，您可以在错误日志中找到可能的原因。 如果您无法写入文件，至少应该抛出一个 IOException。

此外，仔细检查您是否没有共享文件夹名称（也就是说，您确实想写入 SMB 设备上未命名的根文件夹）可能会有所帮助，如果是，请删除后面的两个斜杠之一SMB url 中的端口（应在其之间放置共享名称）可能会有所帮助。
