Android native music player search intent

In the stock music player in Android 2.1 (at least), the artist, album, and track name of the currently playing track are long clickable, which brings up a context menu "Search for NN with:", with links to different apps.

UPDATE

I've managed to extract the logs from my own device, doing a search for an artist, and selecting Google Listen to complete the action:

I will definitely pursue this myself, but this is quite new to me. I'd appreciate assistance here. Does the above mean that as long as I set up MEDIA_SEARCH intent as an entry point for an activity, it'll show up in the select list?

Alright, MEDIA_SEARCH was the right way to go. For reference:

Adding the intent filter is enough to make the application show up in the select list in the media player:

<action android:name="android.intent.action.MEDIA_SEARCH" />

And then the action can be received as follows:

final Intent queryIntent = getIntent();
final String queryAction = queryIntent.getAction();

if (MediaStore.INTENT_ACTION_MEDIA_SEARCH.equals(queryAction)) {
    String artist = queryIntent.getStringExtra(MediaStore.EXTRA_MEDIA_ARTIST);
    ...
}

• INTENT_ACTION_MEDIA_SEARCH
• EXTRA_MEDIA_ARTIST
