title: Problem with android jtwitter authorization using OAuthSignpostClient
body: <p>i am currently working on my first android app ever and i have a problem connecting to twitter to post a status from my Android 3.2 emulator. The emulator seems to be able to connect to the internet as I can use the built in browser to connect to the net and i set up the DNS server.</p>
  
  <p>![application][1]</p>
  
  <p>when I click the update button the entire application fails and gives the following error:</p>
  
  <p><strong>Sorry! The application Burnett Street Hustle v1 (process com.burnettstreethustle) has stopped unexpectedly, please try again. </strong></p>
  
  <p>Since the code compiles and runs up until i click the "Update" button im not sure what is wrong since the error message is also unclear.</p>
  
  <p>here is my code:</p>
  
  <pre><code>public class TwitterTab extends Activity implements OnClickListener {
  
          static final String TAG = "TwitterTab";
  
  
          Button buttonUpdate;
          EditText textStatus;
  
  
          public void onClick(View src) {
  
              String JTWITTER_OAUTH_KEY =  "***************************";
              String JTWITTER_OAUTH_SECRET = "*****************************"; // i do have these codes as the app is registered, they have just been blanked out and are not the cause of the problem.
  
              OAuthSignpostClient oauthClient = new OAuthSignpostClient(JTWITTER_OAUTH_KEY,JTWITTER_OAUTH_SECRET, "http://127.0.0.1:1066/Twitter/Callback.aspx");
  
  
  
              oauthClient.authorizeUrl();
              String v = OAuthSignpostClient.askUser("Please enter the verification PIN from Twitter");
              oauthClient.setAuthorizationCode(v);
  
              Object accessToken = oauthClient.getAccessToken();
              Twitter jtwit = new Twitter("burnettstrhustl", oauthClient);
  
            String status = textStatus.getText().toString();
  
            Log.d(TAG, "Clicked on "+ status);
  
            // Toast
            Toast.makeText(this, textStatus.getText(), Toast.LENGTH_LONG).show();
  
            // set twitter status 
            jtwit.setStatus(status);
  
            //reset status string
            textStatus.setText("");
          }
  
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.twitter);
          buttonUpdate = (Button) findViewById(R.id.buttonUpdate);
          textStatus = (EditText) findViewById(R.id.textStatus);
  
          // Add listener
          buttonUpdate.setOnClickListener(this);
  
      }
  </code></pre>
  
  <p>Im also not sure how to use the callback url properly, which url must go in there for the authorization to occur?</p>
  
  <p>Thanks.</p>
  
  <p>UPDATE Stack Trace: </p>
