Android Question Check correct internet connection

[omidaghakhani1368]

Hi.
I found some code for check internet connection in forum
But you consume i connect to wireless but internet is disable or not connected
In this state,again return true
it is wrong because i cannot send data
how can i detect internet state correctly?

Hello,
HotShoe's MLWifi has a method to detect if you are connected (WiFi or mobile)

also i think you can check whether your device has ip address or not
because each device which is connected to internet has a ip addrees

I currently use the "official" Google recommended way to check an internet connection as explained here: http://developer.android.com/training/monitoring-device-state/connectivity-monitoring.html

The B4A implementation using Reflection library is here:

Sub CheckConnection As Boolean
    Dim r As Reflector
   
    r.Target = r.GetContext
    r.Target = r.RunMethod2("getSystemService", "connectivity", "java.lang.String")
    r.Target = r.RunMethod("getActiveNetworkInfo")
   
    If r.Target <> Null Then
        Return r.RunMethod("isConnectedOrConnecting")
    End If
   
    Return False
End Sub

is this works when wifi is on but there is not any connection?

Yes. It just checks if the device has any internet connection.
