title: Notepad in android - crashing SimpleCursorAdapter
body: <p>I want create my own Notepad, similar like in tutorial on Android site. When I try to run my application, Eclipse opens new tab - "activitythread.performlaunchactivity(activitythread$activityclientrecord intent) line: 2059" with statement "Source not found. Edit source lookup Path...". There is my code:</p>
  
  <pre><code>package com.notatnik;
  
  import android.annotation.SuppressLint;
  import android.app.ListActivity;
  import android.database.Cursor;
  import android.os.Bundle;
  import android.view.Menu;
  import android.view.View;
  import android.widget.ListView;
  import android.widget.SimpleCursorAdapter;
  import android.widget.TextView;
  
  public class MainActivity extends ListActivity {
  
      private NotesDB mDB;
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
  
          mDB = new NotesDB(this);
          mDB.open();
          fillData();
      }
  
      @Override
      public boolean onCreateOptionsMenu(Menu menu) {
          getMenuInflater().inflate(R.menu.activity_main, menu);
          return true;
      }
  
      public void saveNote(View view) {
          TextView textField = (TextView) findViewById(R.id.editText1);
          String note = textField.getText().toString();
          mDB.createNote(note);
      }
  
      @SuppressLint("NewApi")
      private void fillData() {
          Cursor cursor = mDB.fetchAllNotes();
          startManagingCursor(cursor);
  
          SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.item_list, cursor,
              new String[] {NotesDB.COLUMN_CONTENT}, new int[] {R.id.textView_content}, 0);
          ListView listView = (ListView) findViewById(R.id.list);
          listView.setAdapter(adapter);
      } 
  }

  <p>I've not finished, but I think that this simple code should compile. I found out that the problem is SimpleCursorAdapter in fillData() method, but I don't know what is wrong. I'm begging with programming for Android. Sorry for my bad english...</p>
