Tkinter cannot connect to Android display

[jmooremcc]

Running a simple script utilizing tkinter, I get the following error:

/data/user/0/org.qpython.qpy3/files/bin/qpython.sh "/storage/emulated/0/Android/data/org.qpython.qpy3/scripts3/test1.py" && exit
/ $ /data/user/0/org.qpython.qpy3/files/bin/qpython.sh "/stor
age/emulated/0/Android/data/org.qpython.qpy3/scripts3/test1.p
y" && exit
Traceback (most recent call last):
