Android FTP 上传下传文件
如果自己没有FTP服务器,可以到www.5944.net上面去申请一个,申请速度很快,申请了既可以用了.
我提供一个我自己申请的:
FTP服务器: 您的FTP用户名： durian 您的FTP密码是： 7389A913676fdf 您的网址为： http://durian 您的FTP地址是： freehost.22u2.cn 服务器IP是： freehost.22u2.cn 到期时间是： 2016/2/12 13:58:07
不过时间太短了,只能够使用一个月.
FTP查看工具:8utfp
这个用来判断上传的文件是否的确在服务器上面了,可以通过它查看.
简单的东西就不多扯淡了,直接上程序:

<3> : 运行结果:
下载到sdcard的
上传到ftp服务器的
即可以了.
注意android工程manifest里面配置权限:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
