A simple connection checker for Corona SDK

connection.lua

---------------------------------------
-- Test connection to the internet
---------------------------------------
local socket = require("socket")

local connection = {}
local function manual_test(callback, timeout)
	if timeout == nil then timeout = 1000 end
	local connection = assert(socket.tcp())
	connection:settimeout(0)
	local result = connection:connect("www.google.com", 80)
	local t
	t = timer.performWithDelay( 10, function()
		local r, w, e = socket.select(nil, {connection}, 0)
		if w[1] or timeout == 0 then
			connection:close()
			timer.cancel( t )
			callback(timeout > 0)
		end
		timeout = timeout - 10
	end , 0)
end
local isReachable = nil
function connection.test(callback)
    if network.canDetectNetworkStatusChanges then
    	if isReachable == nil then
		    local function networkListener(event)
		        isReachable = event.isReachable
				callback(isReachable)
		    end
		    network.setStatusListener( "www.google.com", networkListener )
		else
			callback(isReachable)
		end
    else
        manual_test(callback)
    end
end
return connection

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
