Searching for music files with mediastore

Question

I have been researching this for hours now. I've looked at android javadoc - MediaStore and I just don't get it. I've looked for examples. Nothing.

I want to search the music library for a string. I have the main idea in my mind (get music library DB, search it like you would a sqlite DB) but I literally have no idea how to do it.

I have also found the URI for external SD media files - MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,

but I don't really know what to do with this.

Some starting points would be nice..

Thank you.

Answer 1

The MediaStore more or less is an sqlite DB. There are many ways to query it. By album, by artist, by playlist, by song, and so on. This will return a Cursor of all songs, for example.

Cursor cursor = getContentResolver().query(
    MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, 
    null, 
    null, 
    null, 
    MediaStore.Audio.Media.TITLE + " ASC");

You can then get specific columns from it like so:

while (cursor.moveToNext()) {
    String title = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.TITLE));
    // Whatever else you need
}
