killBackgroundProcesses does not work on SETTINGS?
<p>I want to kill the background process of SETTINGS by using killBackgroundProcesses. But it does not work without any errors? I use API(8) level 2.2 and having KILL_BACKGROUND_PROCESSES permission in manifest.</p>

<pre><code>  ActivityManager activityManager = (ActivityManager)getApplicationContext().getSystemService(Context.ACTIVITY_SERVICE); 
  activityManager.killBackgroundProcesses("com.android.settings");
</code></pre>

<p>"com.android.settings" is checked by getPackageName of getRunningTasks in ActivityManager.</p>
