title: Remove one of activitys icon from launcher
body: <p>I write a test app with several icon in launcher,such as icon A,icon B and icon C.</p>
  
  <p>What I do like follow:</p>
  
  <pre><code>PackageManager p = getPackageManager();     
  ComponentName mComponentName = new ComponentName("com.i.test","com.i.test.Aofactivitys");
  p.setComponentEnabledSetting(mComponentName,
              PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
              PackageManager.DONT_KILL_APP);
  </code></pre>
  
  <p>But it will remove all my app icons from launcher.</p>
  
  <p>What should I do can remove only one icon from launcher? At the same time,the icon b &amp; icon c still display in launcher.</p>
