title: android hide app icon programmatically just works in my packagename
body: <p>This code works and hides my application icon:</p>
  
  <pre><code>PackageManager p = getPackageManager();
  ComponentName componentName = new ComponentName("myPackageName", "MyLauncherClass"); 
  p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
  </code></pre>
  
  <p>But I need hide another application icon.</p>
  
  <p>When i replace myPackageName and MyLauncherClass with another application package name and launcher class, app force closed.</p>
  
  <p>This means that i can hide my app icon only?</p>
