title: "cannot be resolved or is not a field" -- android -- vogella tutorial
body: <p>i just did this tutorial here: <a href="http://www.vogella.com/articles/AndroidSQLite/article.html#todo" rel="nofollow">http://www.vogella.com/articles/AndroidSQLite/article.html#todo</a></p>
  
  <pre><code>  @Override
    protected void onCreate(Bundle bundle) {
      super.onCreate(bundle);
      setContentView(R.layout.todo_edit);
  </code></pre>
  
  <p>in the last line <strong>Eclipse</strong> underlines the todo_edit and says: 
  todo_edit cannot be resolved or is not a field</p>
  
  <hr>
  
  <p>todo_edit is in my layout folder. </p>
  
  <p>it does not start with a capital letter </p>
  
  <p>i have not imported android.R</p>
  
  <hr>
  
  <p>i dont get where the error might be. ( again: its not even my own code, it was made by professionals )</p>
  
  <p>any ideas ? </p>
