Android: what's the meaning of exported receiver's attribute?
<pre><code>   &lt;receiver
        android:name="MyReceiver"
        android:enabled="true"
        android:exported="true"&gt;
        &lt;intent-filter&gt;
            &lt;action android:name="android.net.conn.CONNECTIVITY_CHANGE" /&gt;
            &lt;action android:name="android.intent.action.BOOT_COMPLETED" /&gt;
        &lt;/intent-filter&gt;  
  &lt;/receiver&gt;
</code></pre>

<p>I don't understand if it's needed to be notified.
If it were true any app could call my receiver with those actions? So If I make it false the system can send the actions to my receiver?</p>
