Espresso: Toggle Network State

Issue

I am currently working on an Espresso test suite that covers offline functionality. In order for me to implement these tests, I need to create a method that I can call to toggle on/off network connectivity. So far, I have been able to toggle WiFi, but I have not been able to figure out how to turn off cellular data.

Any information is greatly appreciated.

You can also perform a really jank workaround. Note: I did this mainly for fun, do not promote the actual use of it ;)

#!/bin/bash

### SET Airplane Mode ON ###
adb shell am start -a android.settings.AIRPLANE_MODE_SETTINGS \
&& for i in {1..5}
do 
    adb shell input keyevent 20
done \
&& adb shell input keyevent 23 \
&& adb shell input keyevent 4;

### Run tests ###

### SET Airplane Mode OFF ###
# NOTE: When Airplane Mode is enabled in API 28, "Mobile network" is disabled. Additionally, since Android Setting's Network & internet 
# is still running in the background, you'll have to select the down action two less times. 
adb shell am start -a android.settings.AIRPLANE_MODE_SETTINGS \
&& for i in {1..3}
do 
    adb shell input keyevent 20
done \
&& adb shell input keyevent 23 \
&& adb shell input keyevent 4;
