python - Can not Access Socket Library in Buildozer Android App -

i trying import socket in main.py

but gives me error below in log-cat of android

i/python  (28346):    file "/root/.buildozer/android/app/main.py", line 3, in <module>  i/python  (28346):  socket.error: port/proto not found  i/python  (28346): python android ended.

it works fine in linux when make app using buildozer crash.am missing module in buildozer?

my buildozer.spec below.
