In an attempt to transfer a file from a remote server to an Android device I ran into permission problems.
It turns out that I do not have a write permission at the location of the SD card (/mnt/extSdCard).
I am using SSHDroid as an ssh server on the Android device and vSSH as an ssh client to engage in ssh on the Android device.
Since both sudo and su seem to be absent on the ssh server app (SSHDroid), I am wondering how I can change/get permission to write to the SD card location. Or is root privilege not enough to change write permissions, and is this thus governed solely by the Android OS, so a limitation of the OS?
What I can do is write to the home path of the ssh server (SSHDroid). This path, however, is very cumbersome and can not be reached from the regular Android filebrowser API. This is the reason why I wanted to transfer the file to an accessible path, like the SD card.
Supplement. The Android version is 4.4.2. The kernel version is 3.4.0-1539356#1.
