Hi Eiver,
You can set capabilities on $pwr_exe/rt_ini with he command
> sudo setcap cap_net_admin,cap_net_broadcast,cap_net_raw,cap_net_bind_service,cap_sys_boot,cap_sys_nice,+eip $pwr_exe/rt_ini
If you are using the same user, I don't understand why permissions should be a problem. You can check the permissions and owner of the ProviewR locks and shared memory in /tmp/pwr*. Your user should have write permissions on these files.
The android app is disclosed and replaced by the HTML5 web interface.
