title: Run app but not from launcher
body: <p>I'm developing an android service application, which reacts on some intents. As you know, intents won't trigger until the app is launched for first time. Because my app is not interactive, I'd like it not to be shown in the launcher (app list). I can do this by removing</p>
  
  <pre><code>&lt;category android:name="android.intent.category.LAUNCHER"/&gt;
  </code></pre>
  
  <p>from the manifest file, but after that, how do I execute the app, as it is not shown anywhere? :|</p>
  
  <p>Thanks.</p>
