How to end a launcher completely?
<p>My application works as a launcher. But, I guess I did something wrong by making it a launcher. For instance, the user selects my application as <strong>Default Launcher</strong> (clicks 'Always'). However, when the user exits from the application, it appears again, because it's the default launcher. How can I fix it?</p>

<pre><code>&lt;activity
      android:name="com.comeks.cocuktablet.Main"
      android:label="@string/app_name"
      android:launchMode="singleInstance"
      android:screenOrientation="portrait" &gt;
      &lt;intent-filter&gt;
           &lt;action android:name="android.intent.action.MAIN" /&gt;

           &lt;category android:name="android.intent.category.HOME" /&gt;
           &lt;category android:name="android.intent.category.DEFAULT" /&gt;
           &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
      &lt;/intent-filter&gt;
&lt;/activity&gt;
</code></pre>

<p>The code comes from my manifest. I also want to make <strong>MAIN</strong> activity launcher.</p>

<p><strong>Edit:</strong>
I realized my exact error. I also wrote a code to start my app on boot. The problem is that when I close my device and open it again, I cannot exit from it.</p>
