• Hi Christy,

  Please try the code below. It should work for you.

  var win = Titanium.UI.currentWindow;
  function loadTweets()
  {
      // Empty array "rowData" for our tableview
      var rowData = [];
      // Create our HTTP Client and name it "loader"
      var loader = Titanium.Network.createHTTPClient();
      // Sets the HTTP request method, and the URL to get data from
      loader.open('GET','http://api.twitter.com/1/statuses/user_timeline.json?screen_name=appcelerator');
      // Runs the function when the data is ready for us to process
      loader.onload = function() 
      {
          try
          {
              if( this.status == 200 )
              {
                  var tweets = eval('('+this.responseText+')');
                  for (var i = 0; i < tweets.length; i++)
                  {
                      var row = Titanium.UI.createTableViewRow({height:'auto'});
              var image = Titanium.UI.createImageView({
                  image:tweets[i].user.profile_image_url,
                  top:0,
                  left:0,
                  height:48,
                  width:48
              });
              row.add(image);
              rowData[i] = row;
                  }
              }
          }
          catch(E){
              alert(E);
          }
          // Create the table view and set its data source to "rowData" array
          var tableView = Titanium.UI.createTableView({data:rowData});
          //Add the table view to the window
          win.add(tableView);
      };
      // Send the HTTP request
      loader.send();
  }
  loadTweets();
  

• BirdHouse: Twitter OAuth for Android & iPhone

  Intro: This isn't an answer to fix your code, but perhaps using BirdHouse as a work around can be a solution. Or, you can check your code with it to find possible corrections that need made.

  Cross-Platform Support & Up-to-Date: BirdHouse has been tested on Android with Linux and Mac as well as on iPhone, both using the latest Titanium Mobile SDK (1.6.2). It has been tested by others and is being maintained to fix any issues.

  Go here for the code and go here for the test app.

  About: The script can send tweets, retrieve tweets, authenticate, "deauthenticate", and send custom API calls to Twitter. For sending tweets, a custom UI popup appears. It is designed to work similar to Titanium's Facebook module.

  David Riccitelli's oauth-adapter doesn't work on Android, but some have forked it to work, such as Ketan Majmudar (go here for his code), I have also tried other OAuth scripts without any luck. I haven't been able to get anything to work, so I developed BirdHouse. Let me know if you have any issues or questions, I'd be glad to help.
