title: My first android application. I tthink onCreate method or the whole class is just not getting called. What could be reason?
body: <p>I have created my first application for android "Hello android". With using Eclipse, ADT and android sdk. First time using all 3. I have below code.    </p>
  
  <pre><code>package helloandroid.test;
  
  import android.app.Activity;
  import android.os.Bundle;
  import android.widget.TextView;
  
  public class TestActivity extends Activity {
      /** Called when the activity is first created. */
      @Override
         public void onCreate(Bundle savedInstanceState) {
             super.onCreate(savedInstanceState);
             TextView tv = new TextView(this);
             tv.setText("Hello, Android");
             setContentView(tv);
         }
  }                         
  </code></pre>
  
  <p>When i run this a blank mobile screen apperas (also 3-4 command prompts opens), that black screen after a while starts looking like typical android mobile screen. Mobile screen works fine but i do not see "Hello, Android" writen any where. What could be the reason. Even i am putting debuggers but control does not come there.</p>
