title: getFilesDir() returning null
body: <p>GetFilesDir() is returning null, which is completely bizarre. What's worse, is my code is...painfully simple:</p>
  
  <pre><code>public class main extends Activity {
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
  
      File f = this.getFilesDir();
      f.getAbsolutePath();
  
      tempClicked((ToggleButton)findViewById(R.id.tempToggle));
  }
  </code></pre>
  
  <p>This will crash on f.getAbsolutePath(). It's currently running in the emulator emulating a 2.3.3 system at 1024x600. </p>
  
  <p>Google returns nothing on this...so why on earth is this happening? And how do I fix it?!</p>
  
  <p>Thanks a lot!</p>
  
  <p><strong>EDIT:: SOLVED!</strong></p>
  
  <p>Well, somewhat...</p>
  
  <p>I think it turned out to be an emulator error. I changed the skin of the emulator to WXVGA, and that then allowed it to write the files correctly. And when I then changed the resolution back to 1024x600 it kept working correctly.</p>
  
  <p>So, if anyone has a similar error, I suggest you play around with the emulator until you find a way past the bug.</p>
