This is a pretty old post, but I'll throw my solution down in case it's
useful to someone else.
I have a class that handles getting the status of the network connection and
making a Boolean and enum value public to the rest of the app: bool
Connected & ConnectivityState State;
In this class there is a public method GetStatus() that basically sets the
value of Connected and State and raises an event StatusUpdated().
In the Activity I register the receiver and listen for the StatusUpdated
event:
...
RegisterReceiver (new NetworkReceiver (), new IntentFilter
(ConnectivityManager.ConnectivityAction));
AppData.Connectivity.StatusUpdated += NetworkStatusUpdated;
...
private void NetworkStatusUpdated ()
{
if (!AppData.Connectivity.Connected)
{
FindViewById<ImageView>
(Resource.Id.connectivity_image).SetImageResource
(Resource.Drawable.network_off);
FindViewById<TextView> (Resource.Id.connectivity_state).Text = "No
Network Connection";
}
else
{
FindViewById<ImageView>
(Resource.Id.connectivity_image).SetImageResource
(Resource.Drawable.network_on);
//
switch (AppData.Connectivity.State)
{
case ConnectivityState.Roaming:
FindViewById<TextView> (Resource.Id.connectivity_state).Text =
"Roaming";
break;
//
case ConnectivityState.WiFi:
FindViewById<TextView> (Resource.Id.connectivity_state).Text = "WiFi";
break;
//
default:
FindViewById<TextView> (Resource.Id.connectivity_state).Text =
"Connected";
break;
}
}
}
...
The broadcast receiver:
...
[BroadcastReceiver]
public class NetworkReceiver : BroadcastReceiver
{
public override void OnReceive (Context context, Intent intent)
{
AppData.Connectivity.GetStatus ();
}
}
...
Now the intent is received by NetworkReceiver when the network connection is
changed, this triggers the NetworkConnectivity class I created to refresh
the status of the network connection and fire the event StatusUpdated, which
is caught by the Activity and allows it to update it's views.
I've tested this and it works nicely, hope it helps someone else trying to
get their head around the problem.
