Probably more important to explain what problem you are actually trying to solve.

I did in my post
"I'm working on an Android app that we only want to allow to run if the user has VPN'd into the network."

The app generates a daily barcode for logging into an instrument we have. We only want internal users to run the app.

If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.

Just to clarify, this is for Android devices connected to your internal network via VPN, and not WiFi?

Are you using a VPN app on the Android device?

Could the barcode that the Android device is generating be uploaded to a secure web site? I'm not trying to change your mind, rather just trying to see if there are any other ways to skin that cat.

That's correct

Not an option

Would you be able to detect if the VPN app itself was up & running? I don't use VPN for anything so I don't know if they're considered "up & running" if no one is logged in to it. In other words, you may get a false positive.

Would you be able to create a web site (it doesn't need to do anything other than exist) that is only available from your internal network (i.e., from inside your firewall)?

Yes, that I could do

In your Android code, try to connect to that site's IP address. If the site truly is not visible to the outside world, and your app can connect to it while using VPN, then you're one step closer to a solution.

Good idea. I'll give that a try.

Thanks

Internal users are any users that are on your company network. Whether they come in via VPN or direct they are seen as the same at the network level. The only suggestion I can find about this is comparing the IP address before and after connection; but it sounds as if that is unlikely to be possible in your case.

This may be one of those issues where the OSI model comes in to play. Depending on which layer your VPN is operating under, you may not be able to acquire such information.

What exactly are you trying to keep from happening?

I have an ExpandableListView is using an adapter that inherits from the BaseExpandableListAdapter base class. On the childview I have a button, in this case with an id of HelloWorld.

When I click on the HelloWorld button and the Click event is fired, the Click event is also fired for other HelloWorld buttons not on this childview, the Toast is displaying more than one group when I expect only one to be displayed.

What I am expecting is for only one Click event to be fired and that event to be associated with the button I click on the childview the button is on.
So there is obviously something I am not understanding here.

I have spent an hour googling but cannot find anything that points to what I am getting wrong.
Any pointers or help much appreciated

public override View GetChildView(int groupPosition, int childPosition, bool isLastChild, View convertView, ViewGroup parent)
 {
     if (convertView == null)
     {
         convertView = _context.LayoutInflater.Inflate(Resource.Layout.ListItemCustomLayout, null);
     }

     var button = (Button)convertView.FindViewById(Resource.Id.HelloWorld);
     button.SetFocusable(ViewFocusability.NotFocusable);

     button.Click += (sender, e) =>
     {
         var groupName = ((Models.Timer)(((JavaObjectWrapper<Models.Timer>)GetChild(groupPosition, childPosition)).Obj)).GroupName;
         Toast.MakeText(_context, groupName, ToastLength.Long).Show();
     };

     return convertView;
 }

I found some RoundCube apps on Google Play Store.

If anyone has personal experience (good or bad are equally valuable) with any such app on your own Android, please share it with me.

Thank you

This, and your other question below, would be more appropriate in the Lounge. They have nothing to do with programming.

Just found some cPanel apps on google play store.

Ratings go from two stars up to four stars.

Four stars costs five bucks, I think.

Anybody got this on their Android ?

With what? All you've shown is code (which has not been tagged correctly so makes it appear pieces are missing), but have said nothing about what is happening, what is supposed to happen, any exceptions that are being thrown, whether you've used the debugger and what it showed, etc.

To borrow a phrase, help us to help you.

I looked at logcat and it seems to be an issue with the listview.setadapter on row 49 but I cant figure out why? I have looked on here for an answer but I just can't make it work. If you guys could help me that would be awesome.

**You may not need these but if you do here they are**
