    copied!<p>I'm currently working toward a mobile android application. The main thing that this app will have trouble with for load times is a Webservice json string that at this current stage is taking too long to load and sometimes causing the app to force close (stalling for too long).</p> <p>Splash -> MainActivity -> HomeActivity This is how our application starts.</p> <p>First we display a Splash, and behind that we run the MainActivity, which consists of the following code:</p> <pre><code>public class HomeActivity : Activity { NewsObject[] news; protected override void OnCreate (Bundle bundle) { base.OnCreate (bundle); SetContentView (Resource.Layout.Main); var request = HttpWebRequest.Create(string.Format(@"http://rapstation.com/webservice.php")); request.ContentType = "application/json"; request.Method = "GET"; using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) { if (response.StatusCode != HttpStatusCode.OK) Console.Out.WriteLine("Error fetching data. Server returned status code: {0}", response.StatusCode); using (StreamReader reader = new StreamReader(response.GetResponseStream())) { var content = reader.ReadToEnd(); if(string.IsNullOrWhiteSpace(content)) { Console.Out.WriteLine("Response contained empty body..."); Toast toast = Toast.MakeText (this, "No Connection to server, Application will now close", ToastLength.Short); toast.Show (); } else { news = JsonConvert.DeserializeObject&lt;NewsObject[]&gt;(content); } } Console.Out.WriteLine ("Now: \r\n {0}", news[0].title); } var list = FindViewById&lt;ListView&gt; (Resource.Id.list); list.Adapter = new HomeScreenAdapter (this, news); list.ItemClick += OnListItemClick; var Listen = FindViewById&lt;Button&gt; (Resource.Id.btnListen); var Shows = FindViewById&lt;Button&gt; (Resource.Id.btnShows); Listen.Click += (sender, e) =&gt; { var second = new Intent (this, typeof(RadioActivity)); StartActivity (second); }; Shows.Click += (sender, e) =&gt; { var second = new Intent (this, typeof(ShowsActivity)); StartActivity (second); }; } protected void OnListItemClick(object sender, AdapterView.ItemClickEventArgs e) { var listView = sender as ListView; var t = news[e.Position]; var second = new Intent (this, typeof(NewsActivity)); second.PutExtra ("newsTitle", t.title); second.PutExtra ("newsBody", t.body); second.PutExtra ("newsImage", t.image); second.PutExtra ("newsCaption", t.caption); StartActivity (second); Console.WriteLine("Clicked on " + t.title); } } </code></pre> <p>The problem I am running into is the app will stick on the Splash page and the Application output will tell me that I am running too much on the Main thread. </p> <p>What is a way to separate the download request to work in the background?</p>
