Android Question How do I detect if 4G is active

[davepamn]

When I turn on 4G and wifi off, I need a way to detect, if a network connection is available.

I need to know the 4G IP address

This seems like an universal need for any synching between the local device database and a server.

Sub Class_Globals
Dim myLan as serversocket
end sub

Sub PingServer as boolean
dim oPhone as phone

if oPhone.IsAirplaneModeOn=True then
bRetVal=false
return(bRetVal)
end if
dim sDeviceIP as string
sDeviceIP=myLan.GetMyWifiIP
if sDeviceIP="127.0.0.1" then
bRetVal=false
return(bRetVal)
end if
if oPhone.GetSettings("wifi_on")<>1 then
bretval=false
return(bRetVal)
end if
if oPhone.GetDataState="DSCONNECTED" then
bRetVal=True
else
bRetVal=false
end if
return(bRetVal)
end sub

can I use
sDeviceIP=myLan.GetMyIP

to determine if I am connected to the network?

Yes
if GetMyIP = "127.0.01" isn't connect, if GetMyIP <> "127.0.0.1" is connect !!

I tested it an getmyip correctly detects 4g

 

[davepamn]

should I use getmyip in all cases and disgard GetMyWifiIP

The best way to know that you are connected to the internet is by sending a request to google with HttpJob.

GetMyWifiIp method is useful when you want to know whether you are connected to a local network (like B4A-Bridge).

 

[davepamn]

Why not create us a simple, Ping API, to test if the server is available to use? The httpjob requires a callback function which is difficult to use when encapsulated in a class and function call from an invoking interface

There's a PING sample posted on the forums.

I read the post and decided it would not work since the call is not synchronous
