When I try running the above piece of code on Android Devices (Samsung and Sony Ericsson) I always get a status as "Connection Available" even when there is no connection.
Use the below code to invoke the test function:
local connection = require("connection")
connection.test(function (isAvailable)
if isAvailable then
print("Connection available!")
else
print("No connection :(")
end
end)
Any help appreciated - Cheers
