title: CheckBox.setChecked() is not working
body: <p>So, this is simply not working.</p>
  
  <pre><code>CheckBox chck_bluetooth = (CheckBox) findViewById(R.id.chck_bluetooth);
  if (mProperties.getProperty("bluetooth") == "true") {
      chck_bluetooth.setChecked(true);
      Log.i("Properties", "bluetooth = " + mProperties.getProperty("bluetooth"));
  } else {
      chck_bluetooth.setChecked(false);
      Log.i("Properties", "bluetooth = " + mProperties.getProperty("bluetooth"));
  }
  </code></pre>
  
  <p>Well, the log told me that bluetooth were set to "true", so I guess there must be a problem with the checkbox.</p>
