title: First installation by Activity: how to destroy that?
body: <p>I have to implement an activity to catch the preferences just after the installation of app.
  This activity must showing only one time, the first time.</p>
  
  <p>In the Manifest I have this:</p>
  
  <pre><code> &lt;activity
          android:name="com.example.android.Setting"
          android:label="@string/settings_name" &gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
  </code></pre>
  
  <p>But I have to destroy that after installation?</p>
