    public class MainActivity : Activity
    {
        HubConnection chatConnection;
        IHubProxy SignalRChatHub;


        public event EventHandler<string> OnMessageReceived;

        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);
            SetContentView(Resource.Layout.Main);

           
            chatConnection = new HubConnection("http://www.mynotyfy.somee.com/");
            SignalRChatHub = chatConnection.CreateHubProxy("ChatHub");


            SignalRChatHub.On("broadcastMessage", (string name, string message) =>
            {
                if (OnMessageReceived != null)
                    OnMessageReceived(this, string.Format("{0}: {1}", name, message));
            });

            var input = FindViewById<EditText>(Resource.Id.ChatInput);

            var adapter = new ArrayAdapter<string>(this, Android.Resource.Layout.SimpleListItem1, new List<string>());

            JoinChat();

            Button button = FindViewById<Button>(Resource.Id.ChatButton);

Then please feel free to do so. The eclipse system will generate a standard framework for your app and you just need to fill in the specifics of your code.

hey all. I am new in android programming. i tried to fill a listview with the datas that i pull from a Xml. I did almost everything and it works fine for now. But the images(320 X 230) in Listview can be seen in some devices(Samsung Galaxy Note 2 but imitation one) and in some devices cant be seen(Samsung Galaxy Note 3, HTC One M7, Samsung Galaxy S4) Can it be because of resolution problems or any other reason ?

Are you using Eclipse or Android Studio? Both have a Master/Detail Flow option when creating a new project. Try that to see what it puts together for you.

Hi All;

Please help as I am going nuts.

Whenever I start a new application I always run it 'naked' just to confirm that everything is ok. From this afternoon all applications I create are coming up with the error as in the logcat dump below. As far as I can see the activity_main.xml file is correct and there is only this one form in the project.

All old applications run ok without hiccups.

Any help appreciated.

Eric

In your RelativeLayout section try substituting "match_parent" with "wrap_content"

"There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult." - C.A.R. Hoare
