title: how to hide app's icon correctly?
body: <p>similar questions have been asked earlier, but the requirement was to hide the app's icon from drawer completely, by removing these two lines-</p>
  
  <pre><code>  &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
  
              &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
       &lt;/intent-filter&gt;
  </code></pre>
  
  <p>However, my case is a bit complicated. i want to hide my app in the drawer and launch it from other apps. if i remove those two lines, i wont be able to launch my app. for example launching a module from xposed framework</p>
