[android-developers] Re: Android 2.3: Music content providers for artists, albums and songs

I would suggest these two intents for starting artist and album
activities on an Android device now. They also work for Android 2.3
and 3.0.
They do not look as good as the other activities build by Google but
they work :-).

For artists:
String query = "";
Intent intent = new Intent();
intent.setAction(MediaStore.INTENT_ACTION_MEDIA_SEARCH);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
query = artistName;
intent.putExtra(MediaStore.EXTRA_MEDIA_ARTIST, artistName);
intent.putExtra(MediaStore.EXTRA_MEDIA_FOCUS,
MediaStore.Audio.Albums.ENTRY_CONTENT_TYPE);
intent.putExtra(SearchManager.QUERY, query);
mContext.startActivity(intent);

For albums:
Intent intent;
String query = "";
intent = new Intent();
intent.setAction(MediaStore.INTENT_ACTION_MEDIA_SEARCH);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
query = albumName;
intent.putExtra(MediaStore.EXTRA_MEDIA_ALBUM, albumName);
query = query + " " + artistName;
intent.putExtra(MediaStore.EXTRA_MEDIA_ARTIST, artistName);
intent.putExtra(MediaStore.EXTRA_MEDIA_FOCUS,
MediaStore.Audio.Albums.ENTRY_CONTENT_TYPE);
intent.putExtra(SearchManager.QUERY, query);
mContext.startActivity(intent);
