GetNetworkType Issue

[joedarock]

My app queries GetNetworkType from the Phone library. However, if I switch to the 3G network from the WiFi network while the app is running, GetNetworkType still indicates "WiFi". Is this a bug, or do I have to do something else before I can read GetNetworkType?

After looking at my code again, I see that there is no "WiFi" result string; I translated the result string from "EVDO_A" to "WiFi" in code. Regardless, it doesn't seem to change when I switch networks.

GetNetworkType simply calls the native TelephonyManager and returns the value. There is nothing special that you should do when calling it, and I don't see any bugs in the code.

You should check PhoneEvents and handle the ConnectivityChanged event.

Thanks Erel,

What I'm looking for is something that will tell me what network is in use at the time of app activation (WiFi or mobile), and also will tell me if the network in use changes while the app is running. Does any one method tell me both, or do I need to invoke a couple of methods?

You need to use PhoneEvents ConnectivityChanged. It will be raised the first time you initialize the PhoneEvents objects and then whenever their is a change.

Hi Erel!

I just want to know, if this is the right behavior.
In the log you can see that I´m checking the "NetworkType" and the "DataState" every two seconds.

When I turn the WiFi on, the "ConnectivityChanged"-event informs about the new type and state.

After that there is no informaion about the WiFi, when I check the "NetworkType" and the "DataState" again.

Is that the right behavior?

Thanks for your help!

[Erel]

GetNetworkType returns the type of the cellular network. So it seems to be the right behavior.

OK. I understand!

Is it possible to get the state of the WiFi?
Is it possible with the ABWifi-library?

 

[Erel]

You can probably get more information with ABWifi library. However the ConnectivityChanged event will always be raised when you start your application. So it can also be used to monitor the WIFI state.
