"Operation not permitted" error - Android Q&A, Help & Troubleshooting

Hey guys
I wrote a script that sends ARP packets using Scapy in Python.
When running that script from a terminal on my rooted phone, it works well. When I try to build an APK (with python buildozer) that would do the same, I'm getting permission errors.
This is the error:
PermissionError: [Errno 1] Operation not permitted

I tried the following things:
=================
1. Setting the following permissions in buildozer.spec file:
android.permissions = INTERNET,ACCESS_NETWORK_STATE,ACCESS_WIFI_STATE, NET_RAW, NET_ADMIN
Click to expand...
Click to collapse
2 Setting SUID during runtime:
subprocess.run(["su"])

Click to collapse
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
3. Setting internet permissions during runtime:
import android
from android.permissions import request_permissions, Permission
request_permissions([Permission.INTERNET])
Click to expand...
Click to collapse
What am I doing wrong? seems that even though I granted the app root permissions, it's still not enough
When running "id" from within the same process, this is the output:
uid=10281(u0_a281) gid=10281(u0_a281) groups=10281(u0_a281),3003(inet),9997(everybody),20281(u0_a281_cache),50281(all_a281),99909997(u999_everybody) context=u:r:untrusted_app_27:s0:c512,c768'
