BroadcastReceiver in android not listening when the app is closed -

i created broadcastreceiver called myreceiver listen volume change event. works fine when app running. but, when close app, stops listening broadcasts.

here's registered broadcast receiver in manifest file.

<receiver android:name=".myreceiver"            android:enabled="true"            android:exported="true">      <intent-filter>            <action android:name="android.media.volume_changed_action" />      </intent-filter>  </receiver>
