Does android:exported="false" restrict system calls/access?
<p>I know that setting android:exported="false" will restrict other applications from using/accessing my application components.<br>
Does setting this attribute will restrict the system as well from using/accessing my components? i doubt.   </p>

<p>for example, i have the following receiver:    </p>

<pre><code>   &lt;receiver
        android:name="ConnectivityManager"
        android:label="NetworkConnection"
        android:exported = "false" &gt;
        &lt;intent-filter&gt;
            &lt;action android:name="android.net.conn.CONNECTIVITY_CHANGE" /&gt;
        &lt;/intent-filter&gt;
    &lt;/receiver&gt;
</code></pre>

<p>The receiver is still receiving broadcasts from the system once the connection state changes (on/of).   </p>

<p>Does this mean that the system calls/access can never be stopped? Please illustrate.</p>
