A UI test to change the preference from 4G to 3G or from 3G to 4G
To run it, you have to give a value to the key network-status.
It means,
uiautomator runtest uitests-preference_network.jar -e network-status network-type
network-type must be either 2G, 3G or 4G.
So the valid lines are
uiautomator runtest uitests-preference_network.jar -e network-status 4G
uiautomator runtest uitests-preference_network.jar -e network-status 3G
uiautomator runtest uitests-preference_network.jar -e network-status 2G
