How to launch an Android app without "android.intent.category.LAUNCHER"
<p>in AndroidManifest.xml</p>

<pre><code>1    &lt;intent-filter&gt;
2       &lt;action android:name = "android.intent.action.MAIN" /&gt;
3       &lt;category android:name = "android.intent.category.LAUNCHER" /&gt;
4   &lt;/intent-filter&gt;
</code></pre>

<p>If removing line 3, the app will not be in the launcher. The question is: where and how can I launch this app in other way? 
Thanks.</p>
