title: How setComponentEnabledSetting works?
body: <p>I have enabled service in my AndroidManifest.xml. And I want to disable it from my code:</p>
  
  <pre><code>getPackageManager().setComponentEnabledSetting(
      serviceName, 
      PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
      PackageManager.DONT_KILL_APP);
  </code></pre>
  
  <p>If I disable the service like above, will it be disabled forever? Or not?</p>
