如何在Android 中实现scp操作

// 复制文件到主机
scp SourceFile user@host:directory/TargetFile


// 从主机复制文件
scp user@host:directory/SourceFile TargetFile
scp -r user@host:directory/SourceFolder TargetFolder

// 从主机复制文件
scp user@host:directory/SourceFile TargetFile
scp -r user@host:directory/SourceFolder TargetFolder
